mproving harvest field efficiency should be the first consideration before looking to purchase a second harvester. Without a chaser bin, it isn’t uncommon for a harvester to spend up to 35% of its time in the paddock unloading – or travelling back to the field or mother bin. According to South East Wheat Producers Association (SEPWA) research, post maturity yield loss can be around 0.5% per day. This, combined with the risk of loss or damage to the crop due to weather conditions which can see downgrading costs of around 40%, puts some urgency into harvest. But with the capital costs of a new harvester getting up to half a million dollars, investing some time into optimising the logistics of harvest with existing equipment should be the first port of call. For an investment between $50,000 and $110,000 in a chaser bin, farmers can improve harvest field efficiency significantly, reclaiming the 35% of harvester unloading and transit time. This ensures the most expensive machine in the paddock, the harvester, is working to capacity as often as possible But with more than 40 manufacturers or importers of chaser bins in Australia, ranging in price significantly, determining which make and model best suited to your operation can be difficult. And while seeing a chaser bin on a stand at a field day is a good start, it doesn’t really give an indication of potential flaws, components susceptible to damage or how the machine will fare after a couple of seasons being pulled around the paddock in the fury of harvest.

Agricultural Survey we asked members to identify problem components on their chaser bins so we could pay them particular attention. Both cross and unloading augers proved troublesome amongst members and difficulty of clean-out was identified as the major gripe (see Figure 1). But members also told us roll-tarps, chains and sprockets failed at some stage. The average size of a chaser bin owned by members was around 20 tonnes (wheat), with most looking to upgrade to 25-30t to match increasing truck and harvester scale. The most common brand owned by members was Finch, with GrainKing and Vennings also well represented. Home-made © Kondinin Group – Reproduction in whole or part is not permitted without permission.

chaser bins were also common in the survey but typically were less than 15t. Kondinin Group engineers determined the best way to see how chaser bins perform was to hit the road, visiting farmers owning 2530t chaser bins with at least one season under their belt. This allowed us to look for any signs of stress, design flaws and inspect build and finish quality. Armed with an ultrasonic thickness gauge to accurately determine material thickness, we visited every state to methodically inspect and measure-up machines, speaking to owners about any issues they had encountered and photographing components.

hat is important in a chaser bin may differ slightly between farmers but some things should be common in determining which machine will service you best. • CAPACITY: While most chaser bins are quoted in tonnage capacity, comparing capacity should be done volumetrically, or at the very least by comparing tonnage capacity of the same product, for example wheat which can be converted to volume by multiplying by 0.77t/m3 • WELDMENTS: Weld quality is essential to prevent cracking under the stresses of operation. Under-cutting, inclusions and porosity in welds should be avoided, as they can become stress concentration points at which cracks can initiate. • FINISH: A quality paint finish will prevent corrosion and provide a smooth surface to assist keeping the bin clean. Resale is undoubtedly improved with a quality coat of paint which has been applied to metal having been appropriately prepared to minimise flaking, chipping, fading or oxidisation. • OUT-LOAD AUGER: In a case of mine is bigger than yours, out-load augers have swollen to over 600mm (24-inch) diameter with unload rates quoted as high as 15t per minute. While the benefit is that truck drivers can get loaded and on the road quicker, overloading or big spills can be a risk with a tonne of grain rocketing out every four seconds. Hydraulic out-load auger direction flaps can assist in directing grain more evenly across a truck and are available for some, but not all chaser bins • CROSS AUGER: Differences in the cross-auger operation are the most common variance in design and can be a cause of problems in operation. Two manufacturers have modified designs to eradicate the cross auger completely, but this also raises the centre of gravity. Cross augers often have a centre bearing or bush which should be easily greased or replaced. Look for augers which have been computer balanced, as this will reduce vibration and prolong the working life of bearings and auger flights. • CROSS-AUGER GATES AND INDICATORS: Cross-auger gate operation allows grain to flow into the

42

Research Report April 2014 No. 51

cross auger, transporting it to the front of the bin where the out-load auger elevates it out of the bin. With PTO driven crossaugers, it is essential to get both augers running prior to opening the gates to prevent cross-auger clutch slip or outload auger jamming. Hydraulically driven cross augers eliminate the need for gates. • RIMS: According to manufacturers’, damage to rims and wheel studs is most regularly caused by loose wheel nuts. Wheel nuts should be checked regularly and tightened to the manufacturers recommended torque. Some manufacturers supply wheel nut indicators to assist in detecting moving nuts. These indicators are also temperature sensitive and will indicate when axle bearings are overheating. • TYRES: Tyres should be adequately load rated and in good condition. Consider width and footprint load to prevent compaction. A Chevron pattern is most common although this aggressive pattern can limit turning ability. While more costly, some manufacturers offer options to improve turning, particularly for operators in irrigated properties • AXLES: The majority of 25-30 tonne bins will have, or be available in a tandem axle configuration. Steerable axles are becoming more common to improve turning circle and walking beam configurations are popular for maintaining ground contact in rough country. Front and rear-wheeled machines typically use a front-steer axle sitting on a turntable, but this may limit suspension options for rough ground operation. • DECALS: Clear and concise decals in English are essential with maintenance interval and safety warnings a basic requirement. Grease point locations are more likely to get regular attention if they are marked with suggested lubrication intervals. • SERVICING AND GREASE POINTS: It goes without saying machine longevity is improved with regular servicing. Grease points should be easy to access and use. Some chaser bins had centralised grease banks making the job easier while the Balzer unit had an auto-lube system fitted. One bearing which is particularly difficult to access is the top outload auger bearing. Ensure this can be accessed and greased. © Kondinin Group – Reproduction in whole or part is not permitted without permission. Freecall 1800 677 761

• BIN WALL THICKNESS: We measured bin wall thickness at the base and side of the bin. While wear will be negated with thicker, or higher-quality steel, the definitive measure of robustness isn’t just down to material thickness (design plays an important role). But thickness does indicate the construction value and gives an indication of rigidity. Almost all the chaser bins measured up featured bin walls constructed using straight mild-steel. • CHASSIS CONSTRUCTION: Chassis design varied enormously but Parallel Flange Channel (PFC) and Rectangular Hollow Section (RHS) were the most common chassis construction materials. Look for a solid chassis with additional material where it is needed on joins, transitions and bends and particularly if the walking beam axles use the chassis as a bump-stop. A-frames should be well strengthened where they join on to the main frame at the front of the bin, as this is a common area for stress cracks. • HYDRAULIC AND PTO CONNECTIONS: It isn’t hard to provide storage and protection for hydraulic connectors and hoses but only about half of the chaser bins we looked at had this provision. Keeping hydraulic connectors off the ground is essential for keeping hydraulic fluid clean. Ensure hydraulic hoses will not be damaged by high-cut stubble and do not impede on the operation of clean-out doors or jack-stands. PTO options for 540 and 1000RPM offer the flexibility to be used with a wide range of tractors. Look for quality and easily replaceable PTO clutches and shafts. • HITCH AND TONGUE: Hitch configurations varied considerably with front and rear wheel configurations. Swivel tongues are essential for operators in irrigated country or with heavy undulation to prevent damage. Look for a heavy or braced underside on the hitch for additional strength. Consider the tractor drawbar load if the chaser bin is a single axle unit. If a smaller FWA tractor will be used to pull the chaser bin, a tandem axle unit will be better suited. Ideally a 150hp+ FWA or 4WD articulated machine is a better option for chaser bins above 25t capacity. • JACK STAND: Jack stands should be solid enough to hold the bin with a full load. They should be easily stowed and easy to raise and lower. Quality geared truck jacks were fitted to the Barber Engineering chaser making raising and lowering simple. www.farmingahead.com.au

IN I N G • LADDER ACCESS: A debate about ladders on chaser bins is in play with some manufacturers, including Davimac, refusing to fit an access ladders as standard, but rather providing a side-wall access door for final clean-out, cameras and large windows for out-loading. These manufacturers cite OH&S implications if an operator was to enter the bin and get injured or killed. Realistically, we think ladders are a must-have and should be wide enough for operators to observe and enter the bin when safe. The absence of a ladder will probably only see operators find more extreme options for entry. • INTERNAL LADDERS AND GROUND ACCESS DOORS: While they do pose the risk of grain hanging and impeding clean-out, an internal ladder or steps are essential with the reality

that operators will inevitably have to enter the bin at some stage for servicing. Alternatively, a ground access door can make clean out simple. • WHEEL CENTRES AND EXTENDER BELTS: For the controlled traffic farming (CTF) operator, wheel centres can be optioned at 3m for most Australian-built machines. To overcome CTF harvester auger reach limitations, belted

extenders pull grain into the bin from outside the bin walls but the additional cost is up to $35,000. • TRANSPORT WIDTH: If transporting on-road, check bin operating widths meet state or local government transport limits. Note overall widths can vary according to tyre selection. • CAMERAS AND LIGHTS: These should be standard features in our opinion. Cameras at the top of the unload auger must have wide-angle lenses but can make loading a truck very simple. Lighting should also be standard – indicators, brakelights and rotating beacons are must-haves for roading and a quality sealed light with a wide-flood pattern on the out-load auger should be standard.

• CLEAN-OUT: Cleanout problems occur where flat areas, struts, bracing and bolt heads protrude into the bin. Look for a smooth internal finish with no flat sections which grain will sit on. Cleanout doors or slides should be easy to operate and locked leaving little or no area beneath the cross auger for grain to sit. This is particularly important for the front and rear of the bin. Out-load augers should have a simple to access door at the bottom to remove the last handful of grain that will sit there. • ROLL-TARPS AND BREATHERS: While the roll-tarp should always be removed prior to out-loading, it is occasionally forgotten and a simple breather valve will prevent damage to the tarp or the tarp frame. A roll tarp that

operated and stows securely is essential. Locking mechanisms vary so be sure the tarp handle will be secure even over rough RR terrain.

A chaser bin can help ensure the harvester is operating at maximum field efficiency and costs a fraction of what a new harvester will cost.

Step 1. Harvest efficiency loss: In-crop work rate (40t/hr) X time out of crop to unload (5mins) Harvester bin capacity (9.5t X 0.6) = Percentage harvest time lost due to unloading time (35%) Step 2. Value of potential loss:

Chaser bin economics

C

alculating the financial return on a chaser bin is difficult because savings are unknown until a disaster strikes and the crop is

damaged. But if viewed in the same way as insurance, a chaser bin enables more grain to be harvested, removing the risk of weather damage to the extra portion of your crop. The cost of owning and operating a chaser bin can be compared to the value of the extra grain that can be harvested each hour because the harvester doesn’t need to stop to empty the grain bin.

that grain after it is weather damaged (40 per cent), the potential loss is therefore $1123/hour. Of course, there are events that will damage the crop completely such as hail, or fire making the reduction in value of that grain 100 per cent. In this case the loss would be $2800 for each hour spent harvesting due to the inefficiency from stopping to empty. But typically weather-damaged grain is downgraded in value by about 40 per cent. Therefore, running a chaser bin would enable an extra $1123 worth of grain to be harvested during each hour of harvester operation.

THE CALCULATION EXPLAINED

STEP 3

A theoretical example shows the calculation is simple using the core influencing factors and assuming potentially damaging weather.

STEP 1

Consider a harvester with a work rate of 40 tonnes per hour, a grain bin that can hold 9.5t and the harvester spends five minutes out of the crop each time the bin needs to be emptied. This means the harvester is spending 35 per cent of the time out of the crop.

STEP 2

In this example, the true harvester work rate is therefore reduced by 35 per cent because it is only in the crop for 65 per cent of the time. Multiplied by the value of the grain being harvested ($200/t) and the percentage reduction in value of

46

Research Report  April 2014  No. 51

The cost of running the chaser bin is simply the tractor running costs plus the chaser bin running costs plus the cost of a driver to operate it. In this example, the tractor running costs are estimated at $60 per hour which includes fuel, depreciation and a repairs and maintenance allowance. The cost of the chaser bin has been simplified to just the depreciation rate per hour. (Calculated by the purchase price, minus the salvage value and divided by its total working life). The hourly cost of running a chaser bin in this example is therefore $41 for depreciation, which doesn’t include interest. The total combined cost of running the tractor and a chaser bin in this example is $126 per hour. © Kondinin Group – Reproduction in whole or part is not permitted without permission. Freecall 1800 677 761

Work rate (40t/hr) X harvest time lost (35%) X grain value ($200/t) X reduction in grain value after weather damage (40%) = Potential loss ($1123/hr) Step 3. Chaser bin cost: Tractor running cost ($60/hr) + chaser bin cost ($41/hr) + driver cost ($25/hr) = Cost to run a chaser bin ($126/hr) Additional workings: Fuel (20L/hr @ $1.50/L = $30) + depreciation ($20) + repairs and maintenance ($10) = Tractor running cost ($60/hr) New value ($85,000) – salvage value ($30,000) Working life (10yrs) X total hours used per year (133)* = Chaser bin cost ($41/hr) *Total hours used (2000ha/15ha/hr ie 2.7t/ha@40t/hr)

Step 4. Percentage cost of securing extra grain (such as insurance for extra grain harvested): Cost to run chaser bin ($126/hr) X 100 Potential loss ($1123/hr) = Percentage cost of extra grain harvested (11.3%)

STEP 4

The cost of running the chaser bin at $126 per hour compared to the value of the potential loss at $1123 per hour is equal to 11.3 per cent. This means it is costing 11.3 per cent to ensure the extra $1123 worth of grain that is harvested each hour. www.farmingahead.com.au

When considering the cost of running a chaser bin as effective insurance, the likelihood of a weather event damaging the crop needs to be considered. Taking into account the recent wet harvest in the \eastern states, it is easy to imagine that the chance of weather damage is high. But you need to remember the long-term pattern — how often in the past 10 years has grain been downgraded due to weather damage?

www.farmingahead.com.au

ADDITIONAL CONSIDERATIONS

There are several other key factors to consider before purchasing a chaser bin: • Cash flow for the capital outlay and interest. • Purchasing a second-hand chaser bin may be an affordable alternative. • Consider the option of hiring a chaser bin, with or without tractor and driver. • Availability of labour (not just the cost). • Availability of a spare tractor at harvest. • Likelihood of crop loss due to weather damage and the likely percentage of damage.

© Kondinin Group – Reproduction in whole or part is not permitted without permission. Freecall 1800 677 761

• Crop insurance costs, what it covers and when it takes effect. • Paddock size and harvesting direction. • Size of chaser bin suitable to the operation balanced with the need for field bins and mother bins. • Other limiting efficiency factors such as trucks being able to keep up with the harvester work rate. • Yield loss on grain harvested after the ideal time.

YIELD LOSS

Research carried out by South East Premium Wheat Growers Association (SEPWA) in Esperance, Western Australia, shows a cereal crop can lose 0.18–0.75 per cent of yield for every day it stands in the field post-maturity. Unlike the potential loss from weather damage, which is variable, yield decrease on over-ripe crops is a known value (within the variations of the research done). Assuming a yield of 2.7t/ha at maturity, a grain value of $200/t and a yield loss of 0.5 per cent for every day grain is not harvested post-maturity, the loss would be $2.7/ha/day (see Figure 1). The yield loss of over-mature crops is not considered in this RR calculation.

e don’t assume this is an exhaustive list of chaser bin Manufacturers. Some manufacturers such as Hyden, Western Australia-based Bedford Harbour Engineering reportedly build a quality chaser bin with a hydraulic cross auger in capacities from 25-40t which carries a three-year warranty. After leaving countless messages, we didn’t hear back from them, but feel free to try on (08) 9880 5838. Other manufacturers such as SA-based Smale Farm Equipment are working on new designs. Smale Farm Equipment is taking a close look at the way it designs its chaser bins and the new prototype was on display recently at the Wimmera Machinery Field Days in Horsham, Victoria. The “Multi-Bin” is still a work in progress, but the basic design which features a stainless steel bin and no cross auger looks simple and functional. The stainless steel bin has a 25,000-litre capacity, or about 20 tonnes, and has the option to be boosted to 32,000L via hungry board style extensions.

Clean as a whistle: The interior of the Smale Multi-Bin is free from spars, struts and other internal structures as the grain feeds by gravity to the unloading auger.

The top of the bin is square and thanks to quite steep walls, the inside is completely “clean”, free from struts and spars, with the grain feeding by gravity to a central point at the bottom of the bin where it is fed into a 408mm diameter unloading auger. Designer Jeff Smale said he hopes to incorporate other changes in the future, including a removable divider, so the bin can be used a grouper, and even the possibility of the “chaser” being used as a spreader. “We are obviously focused on the chaser bin functionality at the moment but will look at other options as well,” Smale said. The unloading auger is 408mm in diameter and plans are already under way to reposition it from the side of the bin to the front, so it folds across the front of the bin, a little more like conventional chaser bin design.

will also keep the overall width to 4500mm. Grain flow is controlled via hydraulics which actuates a standard sliding steel plate design at the bottom of the bin. With the grain feeding unassisted to the lower central point of the bin, the load on the drawbar is four tonnes when the bin is fully loaded. The wheels are set back towards the rear of the bin and Smale has retained its popular detachable axles to help keep maintenance to a minimum. There is no ladder or access to the bin but with no cross auger and literally nothing inside the bin, there is no real need to be in there. Smale hopes to be able to retail the bin for less than $66,000 including GST, which does not include the fire fighting unit. More details: www.smale.com.au

riginating from the town of Kondinin, our own birthplace, the Middle East Engineering (MEE) chaser bin seemed in great condition after five or six seasons. The solid construction and overall sound design obviously contributed to a lack of cracks or other visual damage. The rugged chassis is constructed of heavy wall 250mm PFC, with 250mm RHS used on the A-frame with a bracing strap added underneath the A-frame, with plenty of gussets in all the right places. The heavy-duty walking-beam axle with rear-wheel steer was a standout feature of the Chase MEE bin. The four 650/65-30.5 tyres are mounted on BPW hubs, and the stub axles are welded into a large box section to form the walking beam. There was no evidence of tyres contacting the bin as with many other walking-beam bins. The bin itself is well made and constructed from 3mm plate on the sides with 5mm plate used on the floor. External stiffening ribs are added along the angled section of the bin, with most of the internal bracing forming the roll tarp support at the top of the bin. Few hang points were evident inside

the bin, with cleanout rating as one of the owner’s favourite features. This was no doubt helped by the wideopening bottom doors which run the full length of the bin. Unloading is taken care of by a 400mm diameter auger, which was connected by roller chain from a PTO-driven gearbox coupled to the cross auger. Both the unloading and cross augers were solidly constructed with 5mm thick flights. A large hinging cover allows access to the gearbox and chain drive, which is open to the elements underneath. Hydraulically operated gates were used to shut off the cross auger, and a small indicator arrow is easily visible on the front of the bin. Two windows were fitted for checking the level of grain in the bin. For a machine with several seasons under its belt, the owner only found the need to add video cameras to the auger and bin, plus a rubber spout on the unloading auger. He was more than satisfied with the unloading speed, and had no suggestions for design improvements. MEE offered several options, such as a fire fighting unit and seed and fertiliser divisions RR in the bin. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

Grain King 25t

A

product of WA firm Trufab, the Grain King chaser bin was a wellpresented unit. The 25-tonne bin examined by Kondinin Group engineers had just completed its first season, carting more than 10,000t, and was decked out in custom Claas colours to match the tractors on the farm. The unit featured full hydraulic drive to both the unloading and cross auger, allowing the owner the flexibility to use a non-PTO tractor to operate the bin if required. Separate motors were connected to the individual augers, negating the need for gates inside the bin. According to the owner, the 450mm diameter unloading auger is capable of emptying the bin in about five minutes. Both augers feature 5mm thick flights, and there was a slide at the base of the vertical auger for cleanout. The owner had also added an LED light to the top of the auger to help with unloading when dark. The single, unsprung axle was fitted with 800/65-32 tyres and brakes, and optional stubble mats for tyre protection. The chassis was made from 250mm PFC with 14mm wall thickness, providing plenty of strength. Bracing had been added at points of stress concentration such as where the A-frame joined the chassis rails.

Research Report April 2014 No. 51

The bin was constructed from 2mm plate, with slightly thicker 3mm used on the floor, and was fitted with two windows at the front. It had a high side on the left to increase capacity. External RHS ribs and folds in the bin sides along with pipe and flat bar braces inside the bin added to the rigidity of the structure without creating undue grain trap points. Wheel tubs intruded into the floor of the bin, but they don’t affect cleanout, which was well regarded by the owner. A series of doors are situated in between the stiffening ribs underneath, and are secured by several rods which were retained by spring tension in hooks on the bin floor. While the design provided good access for cleaning, it took a lot longer to open and close the doors due to the number of securing rods. A front-mounted ladder allows the owner to climb up and inspect the bin contents, but no internal ladder was provided for access into the bin itself. At least a platform could be provided at the top of the ladder to stand on instead of a rung. All service points were well labelled with servicing intervals, and the chain drive to the unloading auger was protected inside a guard RR with a hinged door. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

Both augers are hydraulically driven, eliminating the need for gates inside the bin.

LIKES

• Braked axle • Hydraulic drive to both augers • Good to clean out

DISLIKES

• No internal ladder • Multiple bin cleanout doors • Untidy hydraulic hoses lack stowage

COMMENT:

The simple, neat layout of the Grain King is only let down by a mass of hydraulic hoses needing a home. The bin seems well built and finished, but it is hard to tell after one season’s use.

Coolamon Steelworks 30t

H

ailing from Coolamon, NSW, CSW offers four chaser bins in sizes of 18, 24, 30 and 50 tonnes. The quality of construction, heavy gauge of material and attention to detail put the 30t bin reviewed by Kondinin Group engineers at the pinnacle of chaser bin construction. The curved bin sides were built from 3mm plate, while the floor was a heavier 6mm gauge. The unloading auger flight is 5mm thick (6mm at delivery and pickup sections) and the barrel was rolled from 8mm steel. There were very few welded seams in the bin, with the curved profile adding to the stiffness of the structure. Similarly, the inside of the bin was uncluttered and had no real grain trap points. The unit doesn’t have a chassis in the normal sense; with a kind of ‘unit frame’ construction where the strength has been built into the base of the bin. The A-frame was built from 8mm 100x200RHS and heavily gusseted to the bin. The walking-beam axle was also heavily

constructed with the rear axle steerable and 30.5L-32 tyres were fitted. A couple of grease banks would have been nice to prevent crawling underneath with the grease gun. Both augers were PTO driven from the tractor, with a double roller chain transmitting power to the unloading auger gearbox. It only took the removal of two bolts to change between 540 and 10000rpm PTO speeds. The manufacturer claimed the 500mm diameter auger was capable of delivering 10 to 12 tonnes per minute, and a 400mm auger was available as an option (6 to 7t/m). A hydraulic directional spout was also fitted to the top of the auger. Cleaning the bin looked straightforward, with two levers opening full length doors along the bottom of the bin, and a slide door providing access to the base of the unloading auger (although somewhat impeded by the A-frame rail). Hydraulic gates shut off flow to the cross auger, and there were good visible gate indicators up front. The walking beam axle was heavily constructed and had a steering rear axle. Note the sprung rod which was used to open the bottom doors for cleaning.

The rear mounted ladder was easy to access from the ground, but the roll tarp handle did impede the bottom steps a little. Two windows at the front indicate the grain level in the tank at a glance. Optional equipment includes lighting, cameras, weigh RR scales and 3m wheel centres.

LIKES

• Construction quality and finish • Walking beam with steering rear axle • Easy changeover between 540/100rpm PTO • Good cleanout

DISLIKES

• Expensive unit • Tarp handle impedes ladder • Lack of grease banks

COMMENT:

The CSW Crop Hauler is beautifully designed and built and would be an asset to anyone willing to part with additional dollars for a premium chaser bin. Expect high resale values.

f size does matter, then the Balzer is a winner, sporting a massive 600mm unloading auger that dominated the entire chaser bin. Originating from Minnesota in the US, the Balzer range is distributed by DOM Distribution based in Dalby, Queensland. The range included dual and tri-axle configurations, as well as a bin featuring two separate steerable rubber tracked bogies (similar layout to a Case Quadtrac), allowing a high degree of floatation. The massive PTO-driven unloading auger features 8mm thick flighting, 6mm thick barrel and a hydraulically operated directional spout. A swivelling spout was also available as an option. Feeding the unloading auger was an impressive sized 500mm diameter cross auger, which was PTO driven but engaged separately using a hydraulically-actuated disc clutch. Hydraulic gates inside the bin cut off the grain to the cross-auger, but the owner of the model inspected by Kondinin Group engineers has had issues with grain bypassing the closed gates, leading to difficulties starting the cross auger which required care to engage. The heavy chassis was constructed from www.farmingahead.com.au

COMMENT: 250mm PFC, which had been enclosed on the open side, forming a box section and further increasing strength. The A-frame was made from12mm thick 150X200RHS with an 8mm wall thickness. The walking-beam axle was heavily constructed and featured rear-wheel steering. The entire unit was of bolt-together construction of 3mm plate sections, but did not feature as many seams in the bin as other ‘flat-pack’ style chaser bins. All in all, the bin seemed well made, and no structural issues were apparent on the three-year-old unit. The design was let down by the difficulties in cleaning out the bin, as only a single, small cleanout door was fitted to the bin floor. The owner cut another door into the bin pictured, but said cleanout was still too difficult. It could do with an additional window or two to supplement the single front and rear portal. Other issues were caused by the 4.7m-wide transport width, which required two pilot vehicles if towed by truck, or a single pilot if towed by a tractor on the road. The Balzer was well set up for maintenance, and featured colour-coded grease banks, and an auto-lube system to ensure the chains RR don’t run dry. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

eaturing single auger unloading and a bolt-together construction, the 31-tonne J&M chaser bin was one of the more individual machines examined by Kondinin Group engineers. The bin was shaped like an inverted pyramid, with the single unloading auger running vertically up one corner, without the need for a cross auger. This substantially reduced the complexity of the unit, but did raise the centre of gravity. Originating from Ft Recovery, Ohio in the US, the entire construction of the unit is bolttogether so it can fit into a standard shipping container. Models sold in the US are fully welded. And the multitude of bolt threads extending into the bin does create some trap points for grain, according to the owner. Despite this, cleanout was reasonably well regarded by the owner, needing only 100 litres of water to wash it out. A single slide door opened at the base of the bin, revealing the bottom of the auger, and allowing everything to flow out was aided by the conical bin shape. This door was also useful for clearing blockages. Two front and one rear window are fitted, as well as an access ladder at the front. The 450mm unloading auger is PTO

driven (1000rpm) and heavily constructed, with a 4mm barrel and 5mm flight thickness. The manufacturer claimed an unloading speed of 11t/min, but the owner rarely ran it flat out. An internal slide door was used to control grain flow into the auger, and was operated by a long thin hydraulic ram inside the bin. A hydraulic directional spout was fitted to the end of the auger, which also extended lengthwise using a second hydraulic ram. The J&M bin sits on a single, unsprung axle fitted with 900/60 R32 tyres. The main chassis rails were made from 150x200RHS, and the A-frame reduced down to a 100x200 section. All members are 11mm thick and the bin itself was made from bolted sections of 2.5mm plate, with heavier 3.5mm sections towards the base. Five load cells are fitted to the bin and hitch. The owner replaced the fibre slip clutch on the PTO with a mechanical overload style clutch to reduce the fire risk associated with heat from the slipping friction clutch. The complicated fold geometry of the auger has led to some cracking around the hinge, and there was flexing evident between the bin and the A-frame, possibly exacerbated RR by the bolt-together construction. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

akers Hill, Western Australia, manufacturer Neil Norrish has been building chaser bins for several years, and the simple, robust design was certainly a hit with the owner of the model examined by Kondinin Group engineers. Sure some of the welds are a little less tidy than those on other manufacturer’s bins. But if you looked past some of the paint dribbles, spatter and grind marks, there was a solid and capable chaser bin at a very reasonable price. The owner was also pleased with the after sales backup from Norrish Service Group when repairs were needed. The 430mm (17”) unloading auger was PTO driven and fitted with a slip clutch, with a hydraulic drive auger available as an option. Drive from the right angle gearbox to the base of the auger used a double roller chain, which ran in a removable guard which could be filled with grease. Auger barrel and flighting is 3mm thick.

The cross auger was driven by a hydraulic motor through a single roller chain, and negated the need for any gates over the auger inside the bin. The bin was constructed almost entirely of 3mm plate, and was well gusseted and braced externally. The chassis and A-frame were heavily constructed of 8mm thick 100x200RHS, and RHS struts and angle were used to form a ladder section on the main rails, further increasing rigidity and supporting the bin. A series of wide cleanout doors opened between supporting struts underneath the bin, with half the doors opened using a front lever and the other half with a rear mounted lever. The levers required a bit of muscle to operate as they were sprung against their catches to provide closing pressure on the doors. A small slide door opened at the base of the unloading auger for cleaning out. The rungs on the rear-mounted ladder were quite far apart, and the first rung was a long way from the ground. Internal steps are

fitted to allow access to the inside of the bin. The walking beam axle was well constructed but does not feature rear wheel steering. The 24.5-32 tyres were carried on Titan hubs and stub axles, and engineers were pleased to see grease banks fitted to make servicing the axle more convenient. There was some evidence of the tyres making contact on the bin support struts at RR full deflection of the walking beam.

LIKES

• Grease nipple banks for walking axle • Flag holders, LED lights and rotating beacon fitted • Simple, uncomplicated design • Hydraulic flap on auger spout

DISLIKES

onstructed by Minyip fabricator Adam McKenzie, the Tuff chaser bin impressed with its quality construction, smart blue 2-pac paint, and range of features fitted as standard. A 200L hydraulically-driven fire fighter unit (400L optional), lights, flags, roll tarp, oversize sign and flashing beacon are all included in the purchase price. Even the hydraulic directional flap on the end of the unloading auger was included. The PTO-driven 500mm (20”) unloading auger featured a braced 3mm barrel, with substantial gussets on the hinge points. Flighting was 5mm thick, with a 10mm

section fitted at the base. A large slide door at the bottom of the auger allowed excellent cleanout access. The cross auger was 350mm (14”) diameter and made up of three different pitches across the length of the 5mm thick flight. Both slip and overrun clutches were fitted to the drive, with the overrun clutch eliminating any shock load from the sudden stop of the PTO drive train on modern tractors with PTO brakes. The bin was well constructed with a 5mm thick floor, 3mm walls and 6mm lower sections on the front and rear walls. Substantial ribs and bracing inside the

bin keeps everything in shape, and the curved profile of the bin walls add additional stiffness. The internal gate opens vertically, with an excellent indicator fitted to the front wall of the bin. The two windows on the front wall were large and give a good view on bin contents. Cleaning the bin is well catered for with a single wide, long slide that was removed from the rear, and Tee handles are fitted so a spanner is not required. Both internal and external ladders are fitted, and access from the ground is easy thanks to a fold down section. The tarp handle tucks in behind the ladder instead of running across it.

he Chinese-sourced Hornet chaser bin examined by Kondinin Group engineers was certainly no lightweight in the construction

stakes. Assembled in Perth, it seemed it was made entirely of 6mm plate steel. The unit featured bolt-together construction, but most components were large, eliminating many of the bolted joins common to other containerised chaser bins. For example there was only one full length seam in each bin wall, which was made from rolled 6mm plate. The gauge of steel used, combined with the rolled profile created impressive strength and eliminated the need for any structural bracing inside or outside the bin, save for the struts at the top. The full-length chassis was made from a combination of 250mm PFC and plate steel, further increasing rigidity, while the 8mm thick 150x250RHS A-frame was joined to the chassis with plenty of bracing and gussets to prevent stress cracks. Massive front and rear cross-members running under the bin linked both chassis rails together. Both augers were PTO driven and linked by a double roller chain and a hefty looking gearbox. The bottom chain guard would keep out the chaff, but good luck reattaching

it as the four over-centre catches are pretty hard to operate for one operator. The 480m (19”) unloading auger barrel is rolled out of 6mm plate, so no additional strengthening braces were required. Engineers loved the flexible grease lines to the top bearings of both auger sections, allowing easy greasing from the ground. Flow of grain to the cross auger was controlled by the vertically-operating gate, actuated by two hydraulic rams inside the bin. A large pointer outside the bin indicated the gate position, but someone needed to attach an “open” or “closed” sticker. While there were several bolts intruding into the bin, the curved walls and lack of struts or grain trap points should make cleanout simple. Four large doors under the bin open to allow reasonable cleanout access, and were retained with sturdy over-centre catches. The unloading auger featured two access doors, one above the other, for cleanout or unblocking duties. The twin axle walking beam was truly massive and should not give trouble, provided grease points were attended to underneath.

riginating from Balaklava, South Australia, the smart-looking chaser bins produced by Goldney Welding appeared to be built to a high standard. The tandem-axle, 30-tonne bin was well made and solidly constructed, with a braced chassis of custom bent, 8mm plate formed into an angle section with a deep vertical section. The A-frame was from 10mm thick 250PFC, which was attached to the chassis with plenty of strengthening. While the bin floor and sides were made from 2.5mm plate, they were reasonably well braced underneath and internally with stiffening ribs and struts. The gate over the cross auger was operated by a single ram in the centre of the bin. Ladders were fitted to both the front and the rear of the bin, with a fold-down section on the rear ladder making climbing on board a little easier. An internal ladder is provided at the rear for access inside the bin. Great vision of the bin contents was provided by two long windows at the front, which ran almost the full height of the bin, and were complemented by a single rear window. The gate indicator at the front was a simple pointer and easy to see from the tractor cab. www.farmingahead.com.au

Cleanout under the cross auger was accomplished using a pull-out slide from the rear. No centre bearing was fitted on the 300mm (12”) cross auger. The unloading auger was well built with a solid hinge point, and was 450mm (18”) in diameter, but a 500mm (20”) option was available. The barrel was 2.5mm thick, and a generous sized cleanout door is fitted to the base. The flighting on both augers is 5mm thick, and double flights are fitted at the ends of the top and bottom sections of the unloading auger. On the model examined by Kondinin Group engineers, the PTO shaft had been replaced by an optional hydraulic drive unit, which simply bolts into place over the input shaft to allow use with a non-PTO tractor at an optional cost of $3850. While the drive chain was well guarded, the bearing grease nipples were extended to the edge to allow more convenient servicing. Other service points were well labelled, including a single grease nipple on each side which was connected to the walking-beam axle grease points. Engineers liked the convenience, but thought separate nipples would have been better, as the grease may find its way only to RR the bearing with least resistance. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

he Finch chaser bin impressed Kondinin Group engineers in almost all aspects of construction and finish. It also proved popular with the owner of the year-old bin, who had four or five at any one time, trading them regularly every five years. The 30-tonne unit looked the part with curved bin sides, profile-cut stiffening ribs and quality 2-pac paint finish. Just as impressive, but harder to see, was the substantial use of RHS bracing inside the bin, 8mm thick 100x200 RHS A-frame with a stiffening strap welded underneath, and 10mm thick plate used on the bin floor. The owner has experienced no real problems with any of the Finch bins he has owned. And Kondinin engineers could find no evidence of cracking or other damage, and were impressed by the overall presentation

of the unit, with hydraulic hoses routed neatly through the chassis, and excellent paint and weld finish. Both the cross-auger and unloading augers are PTO driven, with 380mm (6t per minute) or 480mm (10t/m) auger options. Hydraulic drive is also available as an option, but only on the 380mm auger size. The unloading auger is solidly built, with a massive stiffening rib running full length. Two full-length gates operate off a single hydraulic ram inside the bin. Gate indicators are easily visible, and two front and rear windows fitted. The ladder is easy to access from the ground, and an internal ladder is fitted. Two hinged doors with adjustable overcentre catches open underneath the bin for cleanout, and a slide door caters for the unloading auger. The owner rates bin cleanout as a standout feature, and it is not hard to see why with the smooth bin sides

providing no grain trap points. The walking beam axle is fitted with four 750/60-30.5 tyres and Titan axles. Wear plates fitted to the sides of the chassis rails limit sideways movement of the walking beam, with the owner replacing them every two years due to use over contour banks. Grease banks on either side mean less time on your back under the bin, and service intervals are well labelled. Finch offer a range of options for the bin, including custom paint colour, hydraulic auger spouts and extensions, and even a RR 400L Honda/Davey fire fighter unit.

he most striking aspect of the Moonta Engineering unit was the large galvanised bin sitting atop twin axles fitted with truck

tyres. The design of the Moonta unit was one of the more unorthodox of the chaser bins evaluated, but the owner was generally happy with its performance over the past two seasons since its purchase. The massive chassis and A-frame were constructed from universal column with a web thickness of 16mm. Needless to say it won’t break in a hurry. The dual axles were separately sprung, both on springs and air bags, and safety cables were attached. Eight 11R 22.5 tyres are fitted, but bomber tyres are available as an option. A rear tow hitch is fitted. The bin was constructed of 2.5mm galvanised sheet, which was folded in several areas to increase its stiffness. RHS braces support the base of the bin, and internal braces and struts add extra strength to the overall structure. However, there were cracks in the corners of the bin, which may have been prevented with some form of corner bracing. There were porous welds in a few areas on some www.farmingahead.com.au

of the seam welds, always an issue when welding galvanised metal. The PTO-driven, 425mm (17”) unloading auger seemed well constructed, with a 2.8mm thick barrel and tapered flighting (5mm thick in centre, 2.5mm at outer edge). A large, hydraulically-controlled directional spout was fitted to the top of the auger. The small cleanout door at the auger’s base was not easy to access as it was placed hard up against the chassis. The cross auger was hydraulically driven, so gates inside the bin were not required. Due to the layout of the auger drive, no chains were used so maintenance was simple and limited to greasing a few bearings and the PTO shaft, and checking the gearbox oil level. The front-mounted bin ladder provided excellent access to the top bearing on the unloading auger. There was no internal ladder, but a bin door provided internal access from the ground. The owner was happy with the ease of cleaning out the bin, with the doors in the base allowing reasonable access, although the entire unit sat very close to the ground. And some of the internal braces in the bin RR did seem to trap grain. © Kondinin Group – Reproduction in whole or part is not permitted without permission. Freecall 1800 677 761

mported into Australia by Vennings, the Argentinean built Cestari chaser bin differs from the norm with a cart-style axle layout. The entire weight of the unit is carried on the fixed rear axle and the steerable front axle with no downward load on the tractor drawbar. As a result, the single pull yoke fitted to the bin is lightweight and easy to handle. For a bolt-together machine, the Cestari bin was solidly built and well finished, and looked fresh for a unit which had already done three seasons. Paint finish was excellent, and numerous decals highlighted service points or safety issues. The front steering axle used an Ackermanstyle arrangement with a tie rod connecting the steering arms on both stub axles to the drawbar yoke. The axle itself pivots in the middle, but the degree of vertical articulation seemed small. Radius arms were fitted to stabilise the pivoting axle, and 30.5 x 32 tyres are fitted on all corners. While cart-style bins can be a little harder to reverse due to the double articulation (drawbar hitch and front steering axle), the owner had few complaints, and rated the wheel arrangement as one of the best features. © Kondinin Group – Reproduction in whole or part is not permitted without permission. Freecall 1800 677 761

Although the bin was a bolt-together the seams were arranged so few bolt heads protruded into the bin. All sections were constructed from 3mm plate, and well supported at the base with external angular ribs, and ribs and struts inside the bin. There were a few leakage points in the bin the owner had to seal with silicone. The ladder-style chassis was made from 8mm thick 100x x200RHS. Both the cross auger and unloading auger were PTO driven, with chain drive and gearbox at the front of the machine. The solid 450mm (18”) unloading auger has a 3mm barrel, and a tapered auger flight with maximum thickness of 5mm. The 400mm (16”) cross auger feeds into the unloading auger, and a large side-mounted inspection hatch opens for unblocking duties. The cleanout slide door at the base of the unloading auger is large and offers excellent access. The hinged bin cleanout doors are all operated from one handle at the rear, but the openings in the bin are a little on the small side. There were a few grain trap points in the bin, so a blow-out would be needed for a proper clean. The sample door/bag chute in RR the bin wall was a handy touch. www.farmingahead.com.au

ailing from Deniliquin in NSW, Jason O’Connor Fabrications manufactures a range of chaser bins in sizes from 15 to 36 tonnes in single and double-axle configurations. The 30t unit inspected by Kondinin Group had completed its first season, hauling almost 10,000t. The double-axle unit presented well, with quality paint finish and attention to detail. The walking-beam had a steerable rear axle, and titan hubs and 30.5L-32 tyres are fitted. The chassis rails are built up from folded 7mm plate to form a deep angle section which taper towards the rear of the unit. The result is a strong frame, which provides plenty of clearance for the axle, or

for the operator to access the base of the bin. The A-frame consists of welded universal beam with a top plate thickness of 9mm and a web thickness of 6mm. The bin itself is well supported by the chassis, and the floor is strengthened with RHS ribs. More ribs are welded inside the bin, and cross-braces and RHS struts add to the strength of the structure. All bin walls are 2.6mm. The top braces sit flush with the top of the bin, and some grain tends to run along the RHS and out the side of the bin. But there appear to be no trap points inside the bin. Gates over the cross auger are operated with a single hydraulic ram in the centre of the bin and there are large indicators on the front wall. Two bin windows are fitted up front and a single at the rear, but they could be a little larger. The fixed ladder at the rear is easy to climb, although a fold down section or flexible lower step would make climbing on a little easier. An internal ladder is fitted. The unloading auger is 250mm (20”) diameter with a hefty 6mm thick barrel and flight. A hydraulic directional spout is fitted. The slide door at the base is large, but the lip at the bottom catches grain when cleaning out the auger. The cross auger is 350mm (14”) diameter with 6mm thick flights, and has a centre bearing which is greased through the long cleanout slide which opens from the rear. Both augers are PTO driven, and the chain drive is protected by a quality guard, which must be unbolted to grease the chain and RR front bearings every 10 hours. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

AFM El Grillo 25t

istributed by Australian Farm Machinery, the El Grillo chaser bin originates from Argentina, and features twin axles in a cart arrangement, similar to the Cestari unit. With three seasons under its belt, the El Grillo bin inspected by Kondinin Group had a few battle scars, with stress cracks around the base of the unloading auger and rust in a few places. But the list of standard features included in the purchase price, such as weigh scales, toolbox, lights and water tank, was impressive. The bin holds 25t and is of bolted construction with longitudinal seams and end plates with lips which wrap around the corners. Plate thickness for the bin and floor is 2.5mm. The bottom section was well braced with box-section struts, and there were several large stiffening ribs and braces inside the bin. Unfortunately the bin seams trap grain, as well as the bag/sample chute. The bin was cleaned through a long pullout slide, which seems wide enough for the job. Grain flow to the cross auger was controlled with two gates which rise open when pulled forward by a hydraulic ram at the front of the bin. The gate indicator was not great, but you can also see the ram

adengi Engineering at Moree, NSW, has been in the business of building chaser bins since 2007 and the unit examined by Kondinin Group had been used for a season with no apparent issues. Engineers were impressed by the overall tidiness of the Badengi bin, with neatly gathered hydraulic hoses, good welds and a decent paint job. The 27t chaser bin sits on a walking beam axle with rear wheel steering and 30.5L-32 tyres. The axle is well built and fitted with FAD hubs, and large cut-outs in the chassis rails allowed plenty of axle movement. No grease banks were fitted, but the bin had

plenty of room to crawl underneath with a grease gun. The bin itself was fabricated from plate steel with 1.5mm sides and 3.2mm floor plates, with 5mm gusset plates helping support the bin floor. Plate ribs were used to help support the bin on the outside, but engineers were unable to inspect the inside of the bin as it was full of grain. The chassis and A-frame were fabricated from lengths of 100x200RHS with a wall thickness of 8mm, and a 16mm thick strap has been welded under the A-frame rails for additional stiffness. Gusset plates are used to provide additional strength at the join between the A-frame and chassis where stress cracks are likely to occur. Cleanout is accomplished by removal of a long slide underneath the bin. The Badengi unit was the only bin inspected that was equipped with an additional chickpea screen which could be installed in place of the slide door. Access to the bin via ladder was good, with a fold-down section at the base. The 480mm (19”) unloading auger featured a heavy stiffening rib, as well as substantial reinforcing around the hinge point. The barrel was 3.2mm thick and the flighting was measured at 6mm, and the manufacturer claims it will unload at 12.5t/ min. A huge slide door at the base of the auger should provide plenty of access for cleaning. The vertical auger gearbox is linked to the PTO driveshaft using roller chain, but the guard must be unbolted for greasing. Grain flow to the cross-auger was cut off using hydraulic gates, and the two gate RR indicators were large and easy to see. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

icking this Ombu ATA26 up secondhand, Swan Hill farmer Darren Hender has completed a harvest and found the 26t capacity unit to perform reliably. The only modification made was increasing the drive cog size on the PTOdriven 510mm (20”) unloading auger to slow it down. Accommodated in a 3.2mm walled barrel, the unloading auger discharges grain at just under 6t per minute with the reduced gearing via 6mm thick flighting. A 465mm (18”) cross auger also has 6mm flight and has a centre greaseable bearing. The Ombu sits on cart-layout wheels with a fixed rear axle and an Ackerman style steering front axle. Thanks to a relatively high mounting position of the bin, the auger transition

chamber clean-out door is simple to access. Internal gates adjust flow to the cross auger but gate position indicators are missing. Instead, operators have to watch for the external ram position which is difficult to see. Bin floor and lower wall thickness is 2.8mm with the upper vertical wall section reducing to 2.1mm. Chassis construction is 8mm thick fabricated 200x90 rectangular section construction with C-section folded steel bin braces rising up to form a ladder truss. Five angular bin braces rise up to the raked walls from each side of the chassis to support the bin. Rear ladder access is excellent and the roll tarp functions effectively but stows behind the ladder, which can be awkward. Bin cleanout is adequate via multiple doors each requiring to be opened using the

hile talking to the owner of this Walsh and Ford 25-tonne bin, Kondinin Group engineers were able to get a good picture of its reliability, as after six seasons, any failures on a chaser bin that will occur probably already have. The unit was showing its age, with several cracks which had been welded and re-welded over the years. The bin sides were made from 2.3mm steel plate, while the floor was actually a thinner 1.5mm. Plenty of 40mm RHS bracing is used to support the bin, with a ladder-truss arrangement extending up from the chassis, and ribs extending to the top of the bin on the outside. There are no internal supports, except for the top struts extending from one side to the other. The chassis and A-frame were comprised of 6mm thick 100 x 200 RHS, with an extra section added to increase the strength of the join between the rails and A-frame. Bin cleanout was effective thanks to the steep walls and lack of trap points. A slide in at the base of the bin allows grain to flow out from underneath the cross auger. The slide door fitted to the unloading auger is tiny and positioned hard up against the A-frame, making it very difficult to use. Engineers liked the large front bin window, and the rear ladder with its hinge-down section. The bin also had a walkway along

the top in the middle of the bin, a feature not seen on other units. Grain flow to the cross auger is controlled with vertically opening gates, with large indicator arrows on the front bin wall. The owner has had trouble with grain getting past the gate at the front of the bin when it was shut, leading to difficult engagement of the cross auger. Both augers are PTO driven, and the chain drive is well guarded, although easy to access for greasing. The unloading auger barrel was made from 2.6mm plate. Standard fitment is a 380mm (15”) unloading auger with a 6mm thick flight, but a 480mm diameter auger is available as an option. The standard cross auger fitted is 225mm (9”), with a 300mm (12”) option. The owner has had issues with sections of auger flight coming loose and jamming the auger, and maintains there were inadequate welds between the flight and the centre tube. He also felt the slip clutch was inadequate, and had to be tightened completely to get sufficient drive. The walking-beam axle appears almost over-engineered it is so massive. A good feature is the vertical thrust blocks which transfer sideways forces to the chassis when turning, instead of imposing a bending stress through the beam. There are a multitude of grease nipples underneath, so some grease banks wouldn’t RR go astray. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

f Kondinin Group engineers needed a benchmark, the Barber engineering 32t chaser bin would be a contender. On first glance at the over-engineered build, a substantial price premium would be expected. But coming in at just over $90,000, those in the market for a quality bin should shortlist this unit along with other betterknown brands. A 510mm (20”) outload auger with measured 5.3mm flight, sits in a 2.6mm thick barrel and has a standard directional spout.

In addition to the rear and internal ladder, a ground access bin entry door is fitted. www.farmingahead.com.au

Cross auger flighting was measured as 4.5mm and is 305mm (12”) in diameter. Hydraulic gates feeding the cross auger are actuated by a centrally located single hydraulic ram. Large indicators on the front of the bin designate door position. Bin floors are constructed using 6mm thick plate steel. Wall thickness is 2.6mm throughout and features curved angle changes adding to bin rigidity. The lower rear section of the bin is punctuated by an access door opening into the bin for clean-out access. The bin can also be accessed via the large rear ladder and internal ladder. Other notable bin features include two comparatively large front and rear sight windows. A heavy duty slide can be removed for cleanout but requires two people to re-install. Owner Matthew Russ reports reliable service after 20,000 tonnes, a very thorough clean-out with blow-out rarely required. No issues were reported with the roll-tarp. Chassis construction is robust and utilises two 5.5mm wall 100mm SHS sections to form a 600mm ladder truss along the length of the bin with a 5.7mm plate skin bracing externally. A bump-stop pad prevents chassis damage in case of extreme rear axle articulation. Drawbar fabrication and transition is heavier still with 5.5mm wall 200x100 RHS section sandwiched between 15mm reinforcing plate on the bottom and 8.4mm © Kondinin Group – Reproduction in whole or part is not permitted without permission.

Tyres are standard 30.5/32. The jack-stand is truck-style 2-speed and is the heaviest of all bins inspected. The owner moved hydraulic hoses to run over the jack-stand to draw-bar attachment to avoid RR damage over irrigation banks. No. 51 April 2014 Research Report

Vennings 30t

ankin Springs farmer Nick Eckerman estimated he had put 30,000 tonnes of grain through his 30t Vennings chaser bin. Despite the light build quality of the bin itself, it is showing no signs of wear. The only issues encountered have been a wayward swinging unload auger after a cotter pin went astray and the stub axles have been refitted under warranty after cracking out around the axle welds retaining the stubs. Unloading auger is 460mm (18”) diameter with a 4.8mm measured flight thickness. Barrel thickness is 1.8mm, the lightest of any chaser bin we looked at. Cross auger and unloading auger are both PTO driven delivering unload rates of 7t per minute The bin is fabricated with sheets of 1.3mm folded, galvanised sheet metal. Putting a good weld on mild steel sheets this thickness is tricky enough, so it isn’t surprising that some of the seam welds between galvanised sheets on the bin are untidy. Light bin build aside, where the Vennings bin looks scrappy is in the attention to detail of small components like bin sight windows which were not cut straight and had a rough finish.

Research Report  April 2014  No. 51

Bin rigidity comes through two folded ribs running around the vertical wall section of the bin walls and nine folded sheet metal wall braces on each side of the bin. Externally, bracing on the 45-degree bin floor is in the form of square-edge flat bar which extends over the chassis where it is welded to a profile-cut chassis mount plate. In contrast to the bin, the main chassis is heavily constructed using robust 380 x 100mm parallel flange channel (PFC) to which the A-frame to the hitch is welded. The drawbar is constructed using 250x90mm PFC. The chassis sits on a 150mm square section axle with 8.7mm wall thickness. Numerous tyre options are available on Titan stubs. The unit inspected was running on 30.5x32 18-ply tyres. Since warranty work was carried out on the stub axle fitment, the owner reports reliable operation. Cleanout is via a full-length slide and despite the gap being the narrowest of any bin we inspected, no cleanout problems were reported by the owner. Who also suggested improvements included a stronger drawbar tongue and RR tighter transport width for roading. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

• Standard directional unloading auger spout • Hitch tongue easily adjusted to appropriate height • Most service points easily accessed

DISLIKES

• Light build quality with some untidy and non-penetrating welds • Bin windows poorly executed • Very narrow clean-out slide and small, hidden access plate on the unload auger cleanout.

COMMENT:

While the Vennings bin has provided the owner of the inspected bin with good service, a couple of significant repairs reflect the lighter build quality approach taken with the unit. But at around $65,000 including GST for a 30t tandem axle chaser bin, it is one to consider for the budget conscious.

Dunstan 26t

F

abricated in a large facility at Kerang in northern Victoria, Dunstan chaser bins have been around for more than 50 years. The Dunstan design incorporates an 1150mm deep fabricated chassis section tapering to 600mm to accommodate walking beam tandem axles. Forward of the axles, a 200mm x 130mm wide universal beam continues the chassis line to a sturdy hitch mounted to the truncated A-frame drawbar. Angles and transitions are supported with reinforcing plates and gussets. Boasting a 510mm (20-inch) unloading auger is capable of shifting 12t per minute with a barrel wall thickness measured at 2.7mm and flight thickness at 7.6mm. Augers were driven via PTO, the unload auger utilising a 130hp rated gearbox while the cross-auger was driven via a double chain. The unloading auger access for cleanout was very good via a large sliding access door secured with an over-centre lock. Access for clean-out was not impeded by the draw-bar at all. Cross auger flow was controlled by a single ram in the centre of the bin actuating flow doors with adequate external indicators on the front of the bin. Front and rear bin wall sections feature two well-positioned sight-windows and are tabbed and folded on the edges for welding to the 2.6mm bin walls giving the design www.farmingahead.com.au

both structural strength and resistance to cracking. The walking beam axles are solidly built with square section steel. Titan hubs are refitted with SKF bearings replacing the stock Chinese components and are lubricated via hub centre grease nipples. Walking beam pivot pins incorporate machined paths rifled along the pivot length for even lubrication. Tension indicators on the wheel nuts are fitted as standard. The only criticism of the design was found on an irrigated farm where admittedly the bin had seen a couple of years of very hard service. It was evident that in situations where sharp undulations, for example, when manoeuvring over irrigation tailings channels or contour banks, walking beam articulation could see the rear axles impact the chassis. In the example seen, damage to the chassis had resulted, buckling the lower flange and spine of the chassis section out to the point where tyres rubbed. This could all be easily solved with the addition of some heavy bump-stop plates or gussets on the lower chassis section above the rear axles. Rear access via the ladder could be improved with a fold-down bottom section but the roll tarp functions well and can be securely fastened. Cleanout is via a large full-length slide with locking fasteners and an ample RR handle. © Kondinin Group – Reproduction in whole or part is not permitted without permission. Freecall 1800 677 761

DISLIKES

COMMENT:

Build quality and finish is of a high standard. Inclusions are impressive with adjustable axle, unloading auger direction spout, roll-tarp, and lighting included in the list price of just over $70,000 including GST. Overall, we reckon this represents good value for a single axle model.

PRICE:

$70,400 including GST MANUFACTURER CONTACT DETAILS: Davimac 53 Wellington St, In the absence of a rear ladder, the only way to enter the Davimac chaser bin is via the side-wall door, meaning that it can only be done when the bin is nearly empty.

A hydraulically driven cross auger means no internal gates are needed to control flow. Internally the bin is clean with steep sides and no cross-bracing allowing excellent cleanout.

uilt in Molong southern NSW, the Davimac range of chaser bins are unique in that all models have a hydraulic drive 405mm (16”) cross-auger with flighting thickness measured at 5.5mm. Notably, the cross auger does not have a centre bearing. The use of a hydraulically drive means flow control gates are not needed. A single lever operates drop-down doors along the length of the bin. The 510mm (20”) PTO driven unloading auger is housed in a 2.7mm thick barrel and features a 6.4mm auger flight. This combination delivers unload rates of around 7-tonnes per minute according to the owner. A directional spout is standard. The bin is well constructed and finished and has two triangular wheel wells fabricated

into it. Two sight windows in the front of the bin indicate fill level but there are none at the rear. The main chassis is a constructed 520mm deep C-section channel with four 150mm wide manufactured channel sections rising up from the chassis to support the bin walls. Bin walls were measured at 2.5mm sheet construction making them on the lighter side by comparison but the steep wall angle and heavy bracing make up for the variance. The bin sits on a heavy duty axle with 2.6-3m adjustable track width using a mechanical ratchet suited to controlled traffic operators and regular roaders. The bin is also repositionable forward and aft. A quality roll-tarp is fitted and simple to

operate and stow, but no bin-breather was fitted in-case the decal is missed and the roll tarp is forgotten prior to unloading. An operator manual was mounted to the machine in a weather-proof canister. The only modification the owner will make after a season of use is to add a rear ladder. The omission of one as standard is OH&S gone too-far with operators likely to go to more risk to see inside the bin than if a ladder was fitted. Service points are all easily accessed including the top unload auger bearing which can be reached from ground level. The unit inspected was fitted with 900/60R32 tyres but 800/60R32 size is standard. Quality welding is evident and RR paint finish is excellent. www.farmingahead.com.au

or a bolt-together chaser-bin, the Elmers is relatively-heavily built with large cross and unloading augers. According to Dave Fagan from Cowrabased Geronimo Farm Equipment, they can squeeze three of these into a shipping container when broken down. Its 460mm (18”) cross auger and 510mm (20”) unload augers are 1000rpm, 20-spline PTO driven via 4-rib v-belt and gearbox respectfully. Hydraulic drive is optional at a $5500 premium. Internal gates are actuated by a single hydraulic ram, indicated externally with a large indicator arm. Flight thicknesses were measured to vary from 4.5mm to 6.1mm for the cross auger while the unloading auger varied from 5.6mm to 8.5mm. Unload auger barrel measured 4.5mm in thickness. The cross auger does not have a centre bearing. Bolted bin sections graduated in gauge from 4.5mm at the floor level up to 3.2mm up the batter with the remaining batter and vertical section measuring 2.3mm. Sections are bolted through join plates with the corners meeting to bolt into an angle section. Internally ribs brace at these sectional joins. A 100x200mm rectangular section drawbar with 8.5mm wall thickness is pinned to the lower chassis section of the same sectional profile. Gusseting on the side, top and bottom of the drawbar transition is rounded for stress minimisation. A cut-and-folded ladder upper truss chassis section extends along the length of the chassis and is bolted to the bin. Standard tyres are 900/60R32. The chassis is bolted to a square axle section guested on the lower side and is offset to lower the bin centre of gravity. Around the back, the roll-tarp is simple to use and the handle easy to stow. Ladder access is good with a drop-down lower © Kondinin Group – Reproduction in whole or part is not permitted without permission. Freecall 1800 677 761

ladder section. Full-length cleanout doors are opened using a large spanner, which was missing on the unit inspected. We would rather see a permanently fixed handle for this reason. Lighting on the auger, at the rear and inside the bin is standard. Load cells are RR optional.

LIKES

• Large front and rear bin windows • Heavy gauge axle and bin wall construction • Simple service access with grease banks to bearing access.

DISLIKES

• Jack stand placement males operation difficult • Bolted construction will required checking and re-tightening • Internal bolt protrusions will make cleanout more difficult

COMMENT:

Despite the bolt together construction, the Elmers unit is well fabricated with heavy duty augers and bin fabrication. Exchange rate fluctuations in mind, we think Geronimo need to sharpen their pencils when comparing pricing to comparable capacity single axle models.

hile we could only get our hands on an 18t Parkes Steel Products chaser bin, the 25-tonne model is identical but for an additional 1200mm in bin length. 305mm (12-inch) cross and 430mm (17-inch) unload augers are PTO driven through a Bondioli Pavesi 170hp rated gearbox. Flighting thickness was measured at 6mm for both augers with the cross auger pitch varying front to rear to provide even unloading. Unload auger barrel measured 2.8mm thick. Claimed unload rates of just over 6-tonnes per minute are on the lower side of the competition. Hydraulic drive is optional but a directional spout is standard.

excellent bin clean-out. Top and bottom doors on the unload auger chamber also provide ample access for cleanout although the lower slide door is hard to access behind the drawbar. Bin wall thickness was measured to be 2.8mm at the bottom and middle with the upper section thinning back to 2.1mm but featuring a curve profile for additional stiffness. A central folded rib in the middle of the raked section of the bin also gives rigidity but internally may see a small amount of grain left on the horizontal section of the fold. Externally, profile-cut sheet sections rise up the bin walls for added strength. Main chassis is a ladder truss constructed using heavy 8.5mm wall 200x75mm RHS with the A-frame draw-bar fabricated using the same section. All transitions are gusseted with rounded profiles to minimise stress concentrations. Internally, flow gates are controlled by a single centre ram. From a service perspective, centre bearing grease nipples on the 30t rated Titan hubs are easy to service, but chain-drives and bearings off the bottom of the gearbox and at the top of the unloading auger and are trickier to get to. The centre bearing for the cross auger could do with a grease line for easier access. The bin sits on a heavy 9mm wall, 250mm square section axle offset to lower the overall bin height. 30.5L-32 tyres are standard. Bin weld quality is excellent with good penetration all-round and finish of the twopack paint is worth shelling out for the additional cost. Up front, the gate indicator is easy to read but keepers for hydraulics would be a simple RR and worthy addition. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

COMMENT:

At under $70,000 including GST, the Parkes Steel Products 25t chaser bin represents good value for money in the single axle category. Other bins in this category are sporting larger outload augers but without getting into mine-is-biggerthan-yours territory, the Parkes steel products 25t is capable and well built.

he 2011 model Akron we inspected had done three years of service with Gerogery, NSW based importer and contractor Neil Philips. The Akron is also available from South Australian based Vennings, making it the third make that they sell. The Akron, like the Ombu and Cestari, is a cart-style chaser bin with a fixed rear axle and an Ackerman style steering front axle utilising a towing yoke. The unit inspected had a 32,000-litre capacity; in wheat terms, this equates to about 25t, but newer models extend the bin slightly to accommodate 28t. Cross and unloading augers are PTO driven. The 510mm (20”) unload auger is encased in a 2.7mm thick barrel and has a multiple sectioned auger flighting ranging between 3.5mm closest to the shaft to 4.5mm on the outer flight. There is no direction spout on the unload auger nor is one optionally available. The cross auger is a 405mm (16”) diameter, has a centre bearing and also uses multiple thickness flight gauge ranging between 2.8mm to 4.1mm. The auger transition chamber has an access slide for cleanout although this had evidently required a hammer to encourage opening on a number of occasions. The operator had added reinforcing plate and brackets to the inside of the bin where the unload auger attached and hinged. Internally the bin had four wall spars on each side with cross bracing between them and an internal ladder. A 50mm wide lip where the top bin section was bolted to the raked wall section carried some residual grain dust, but otherwise cleanout looked to be good. Bin gauge ranges from 6mm at the base to 4.5mm on the upper floor with walls measuring 3.2mm in the lower section and www.farmingahead.com.au

2.4mm for the upper walls. Around the back a good quality folding ladder is fitted with road indicator and beacon kits fitted as standard but there is no rear window. An optionally fitted roll tarp provides ample service and a rear-hitch is fitted. Internal gates to control grain flow are actuated by an external ram but no gate indicator is fitted and the ram is difficult to see from the tractor cab. Weld quality was good and finish is in a polyurethane paint. Bottom cleanout doors are opened using a large, easy to use handle to reveal numerous oval shaped slots for residual grain clean-out. Diamond-tread tyres fitted on the model inspected were 30.5/LR32 but standard is 24.5LR/32. Maintenance was relatively simple with all grease points easily accessed with the exception of the top unload auger RR bearing.

The cart style wheel layout with Ackerman front wheel steering. Gate indication is an obvious omission.

LIKES

• Generally good build quality • In good shape for a bin that has carried 50,000 tonnes of grain. • Cleanout doors are easy to operate

DISLIKES

• Some components could be strengthened for example auger attachment to bin. • No gate indicators are fitted • No rear bin window is fitted

COMMENT:

The Akron is worth considering if in the market for a cart-style bin. Only minor tweaks are required to make it better.

eavily built, the walking beam tandem axle Lusty 31t chaser bin by Swan Hill based Pumpa Engineering impressed the Kondinin Group researchers and with a few minor modifications to the design and build would give good service at harvest. Unable to track down a recent owner within reach, we settled for a look over a newly finished unit at the factory. The front end is neatly built and finished thanks to wrapped hydraulic hoses and hanging racks. Build quality is heavy with the 510mm (20”) unloading auger sporting a 5.7mm thick flight and housed in a 6mm thick barrel. Flight thickness was measured to be slightly

Research Report April 2014 No. 51

heavier on the 305mm (12”) cross-auger at 6mm. Both augers are PTO driven. An angled 255mm deep universal beam stretches back from the adjustable hitch to the chassis where a couple of slightly undercut welds were spotted on the join. Most other welds checked were of a good standard. The main chassis continues the same profile universal beam on each side for the length of the bin and is gusseted above the axle fixing plate. As with the Dunstan design, the addition of a couple of gussets or a bump stop on the chassis above the rear axle may prevent damage in sharply undulating country. Two rectangular section lengths of steel are stitch welded together to form the walking beam. But it would be good to see a full weld or a single heavy section used to prevent potential corrosion along the unwelded gaps. The bin base is 4.7mm thick while the wall thickness for the rest of the bin was measured at 2.5mm thick. Structurally, five sets of bracing cross the bin internally but most are flat section steel and would not cause grain residues to hang. A rear-steer axle is optionally available at an additional cost of $4330. Hubs are made by Titan and are centre greaseable. Tyres are 30.5L/32 as standard. Other service points for the walking beam pivot are easy to access under the bin but PTO bearings require guarding to be unbolted first. The top of the unloading auger does not have a grease point. The roll-tarp works well although the telescopic handle was a bit sticky to extend. Bin cleanout is via a full-length, comparatively wide slide. Auger transition chamber cleanout has a large slide door, but RR is partially obstructed by the drawbar. © Kondinin Group – Reproduction in whole or part is not permitted without permission.

While most welds were good, there were a few in high stress areas that could have been a bit better. Paint finish however was very good.

LIKES

• Paint finish was excellent • Overall heavily built • Very neat hydraulic lines and stowage

DISLIKES

• Rear access ladder needs a drop-down section • A couple of untidy welds • PTO bearing service requires guard unbolting
