4.1

Safety Rules Before starting work, familiarise yourself with all the controls and instruments and their functions, as it will be too late once you have set off.

An adequate safe distance must be maintained from the cutting tools while working!

Safe operation of the mower unit is only possible through appropriate use of the cutting blades according to directions.

Check the mower unit every time for damaged, missing and worn cutting blades and replace cutting blades if necessary!

Only replace missing and damaged mower blades in sets as specified by the manufacturer to prevent danger resulting from imbalance!

Check the parts fastening the blades on every change of the cutting blades according to regulations specified by the manufacturer and replace if necessary!

It is particularly important to check how far the blade retaining pin has been grooved on its internal radius by the blade. Replace the blade holder with a new one with an unused blade retaining pin latest after achieving a groove depth of 3 mm, i.e. if the internal radius is reduced by 3 mm.

Similarly, check the riveting of the blade pin in the blade holder and the wear on the blade holder outer edge. If necessary, replace all the blade holders on the mower discs with new blade holders.

The safety guards must be checked regularly and worn or damaged safety guards must be replaced!

Protective equipment on the mower unit, for example canvases and hoods, protect against flying stones and the like as well as from access to dangerous areas.

For this reason they must be placed in safety position before starting work!

Squashing and shearing points arise while the mower unit is being swivelled from the transport position into the working position and vice versa. For this reason, do not stand between the tractor and mower. The swing process must be undertaken with the mower in horizontal position.

The glide discs must be on the ground before putting into operation and while working!

Stones and similar objects can be flung about even when the mower unit is being used correctly. Therefore, nobody should remain in the danger zone.

If you have encountered an obstacle, stop the mower unit immediately and check for damage!

Wear close-fitting clothing when working on the front attachment. Do not wear loose clothing!

Keep the machine clean to prevent fire!

Before starting and before putting it into operation, check the area around the machine (children!). Ensure that you have an adequate view!

Passengers must not be carried on the machine while working or during transport!

Always connect the machine correctly to the tractor and connect and secure the machine to the prescribed couplings!

Always place the jack in the appropriate position when hitching and unhitching the machine – stability!

Use special care when hitching the machine to the tractor and when unhitching the machine!

Make sure that balance weights are correctly fixed at the provided points!

Observe the permissible transport dimensions!

Observe the maximum permissible axle loads and total weights!

Check and mount transport equipment – such as lights, warning devices, and if required protecting devices and guards!

Operating devices (ropes, chains, linkages etc.) of remotely controlled mechanisms must be positioned in such a way that they do not trigger unintentional operation in any transport or operating position!

For road travel, prepare the machine and lock any moving parts as prescribed by the manufacturer!

Never leave the operator's platform when driving!

Always adapt your ground speed to the ground conditions! Avoid making sharp turns when driving up or down slopes or when driving across the slope!

The operating, steering and braking behaviour will be affected by the trailed machine! Therefore ensure adequate steering and braking power!

When making turns, always take into consideration the width and/or inertia of the machine!

Use the mower unit only when all the guards are fitted and in the protection position!

Special care is required when working near roads and buildings!

Ensure all persons stand clear of the operating area and of the area of danger!

The working tools of the cutter bar continue to run even after switching off the drive. Do not stay close to them until they have stopped.

Do not stand in the rotation area or swing area of the mower unit.

Safety Rules Check for pinch and shear points on parts that are operated with external force, for instance by hydraulics!

Always disengage the PTO shaft, stop the engine and remove the main switch key before attaching or detaching the universal drive shaft!

Secure the mower unit before leaving the tractor!

Lower mounted attachments fully to the ground!

Switch off the engine and remove the ignition key.

An overload or free running coupling is to be attached on the device side when using universal drive shafts with overload or free running couplings which are not covered by the protective equipment on the tractor!

Never let anyone stand between the tractor and the machine without securing the vehicle against rolling away by putting on the parking brake and/or through the use of wheel chocks!

ATTACHED MACHINES Before attaching the machines or detaching the machines from the 3-point linkage, move the control lever to a position in which unintentional raising or lowering is not possible!

When attaching mounted machines to the 3-point linkage, the linkage categories of tractor and machine must match, otherwise make necessary modifications!

There is risk of injury due to crushing or shearing in the area of the 3-point linkage!

Do not stand between tractor and machine when operating the remote control unit for the 3-point linkage!

Always ensure that there is adequate sideways locking of the tractor three point rod when the machine is in transport position!

When driving on the road, with lifted mower unit, the operating lever must be secured against falling down.

ATTACHED DEVICES Secure the devices from rolling away.

Observe maximum permissible load capacity of couplings and swinging drawbar or hitch facility!

When hitching the machine to the drawbar, ensure that there is sufficient movement at the hitch point!

PTO OPERATION Only use universal drive shafts specified by the manufacturer!

Always ensure that the guards for the universal drive shaft and PTO stub shaft are installed and in a good condition! Ensure that the guards properly cover the universal drive shafts, both, in the transport and in the working position!

Always ensure that the universal drive shaft is correctly installed and securely fastened!

Secure universal drive shaft gear against rotating by hanging the chains.

Before engaging the PTO shaft, ensure that the selected speed and the direction of rotation of the tractor's PTO shaft matches the permissible speed and the direction of rotation of the drive assembly of the machine!

Always ensure that nobody is in the danger zone of the machine before switching on the p.t.o.shaft!

Never engage the PTO shaft when the engine has stopped!

When operating the PTO shaft nobody must stand in the vicinity of the rotating PTO stub shaft or universal drive shaft!

Always disengage the PTO shaft when the turn angle is extreme or when the PTO drive shaft is not used!

Attention, after the PTO has been disengage, flywheel mass continues to run! Do not step too close to the machine during this time! You are only allowed to work on the machine when everything has stopped moving.

Cleaning, lubricating or adjustment of the p.t.o. shaft driven machine or universal drive shaft is only permitted when the p.t.o. shaft and engine are switched and the ignition key is removed!

When the universal drive shaft is not connected to the tractor, it must be kept on the storage yoke or suspended with a chain!

After uncoupling the universal drive shaft, push the protective guard on to the PTO stub shaft!

In the event of damage, this must be rectified immediately, before commencing work with the mower unit.

HYDRAULIC SYSTEM The hydraulic system is under high pressure!

When attaching hydraulic cylinders and motors, ensure the stipulated connection of the hydraulic hoses!

0293 491.8 - ZBA/BA DISCO 3050 FC Plus / 3050 FC / 3050 F Plus / 3050 F / 3000 FC

4.3

Safety Rules When connecting the hydraulic hoses to the tractor hydraulics, it is important to ensure that the hydraulics are depressurised both on the tractor side and the machine side!

For hydraulic function connections between the tractor and the machine, the coupling sleeves and plugs should be marked to avoid incorrect operation! Interchanging connections causes reversed functions (e.g. raise/lower) – Safety hazard!

Check hydraulic lines at regular intervals, and replace them in case of damage or ageing! Replaced hydraulic lines must correspond to the technical requirements of the equipment manufacturer!

Checking for leaks is hazardous. Use suitable aids to check for leaks!

Fluid escaping under high pressure (hydraulic oil) can penetrate the skin and cause serious injuries. If any fluid penetrates the skin, consult a doctor immediately!

– Risk of infections!

Before performing any work on the hydraulic system, lower the machine, release the pressure from the hydraulic system and stop the engine!

Prior to Operation Matching the universal drive shaft Before using the mower unit for the first time, the hitching and universal drive shaft must be adjusted to the tractor.

CAUTION! The maximum universal drive shaft inclination and quiet running of the mower unit can only be achieved by correct hitching.

8

It may be necessary to match the universal drive shaft because of the varying PTO shaft positions of the different tractor types.

Pull the universal shaft apart and push the universal drive shaft halves onto the drive shaft of the machine and the other half onto the tractor PTO shaft using the long protective funnel.

Swing the machine into the working position. Hold the universal drive shaft halves next to each other and check the length with the machine in the lifted out and lowered positions.

(Fig. 8)

Observe the maximum permissible shaft length (LB).

Try to ensure maximum possible overlapping of profile tubes. The universal drive shaft must only be pulled apart when operating by half the size of the sliding profile cover (PU) when in a compacted condition (LZ).

In the shortest operating length, the universal drive shaft halves must not collide against each other. A minimum clearance (a) = approx. 40 mm must still be available.

Cut the male and the female guard tubes uniformly.

Operation Setting the cutting height ATTENTION! If the cutting height is too low, it will cause excessive wear of the mowing disc and the blades.

Z The cutting height can be adjusted by changing the tilt angle (Z) (Fig. 3) of the mower head.

68500F

3

High cut: For this, the latch (1) (Fig. 1) needs to be engaged.

The head can no longer tilt downwards so that a greater cut height is achieved. The upper link is to be shortened until the desired cut height is achieved (Fig. 4).

Low cut: For this, the latch (1) (Fig. 2) needs to be disengaged.

The springs (2) (Fig. 2) should be tightened more. The upper link is to be lengthened until the desired height of cut is achieved (Fig. 4).

4 Reducing the cut height below the prescribed height (40 mm) is not possible. In most cases, the prescribed cut height can be used to mow. The latch must then be disengaged.

With extremely uneven ground conditions, the latch should be engaged and the angle of inclination (Z) of the machine should be reduced. This produces a greater cutting height and reduces any danger of propelling foreign objects forwards.

Operation Mowing DANGER! The ground to be mowed is to be kept free from foreign objects.

• Change over the front power lifter to single-action (just lifting, not pressing down). The mower unit lowers under its own weight. The mower unit must not be additionally loaded by the front power lifter.

NOTE! When using tractors with front axle suspension, the optimum ground matching of the mower unit can no longer be guaranteed. This applies particularly when the ground is uneven.

• If necessary, deactivate the front axle suspension to achieve the set weight relief.

If the front axle suspension cannot be deactivated: • Set the weight relief weaker – see Weight relief, page 6.11 and • Reduce the traverse speed when mowing.

• Lower the mower unit to the ground.

• When working, the hydraulic control lever for the front power lifter must be set to Floating Position (freewheel).

• Swing down the safety guards on both sides.

• Before entering the field to be mowed, turn on the tractor PTO shaft and slowly accelerate to the maximum permitted PTO shaft speed (– see Specifications, page 5.1). The whistling noise of the cutting discs at high speed is completely normal and is generally muffled during actual mowing.

• Move into the forage.

• Always operate using the hand throttle while mowing to avoid fluctuations in the rotational speed.

• The driving and crawling speed are to be set according to the respective operating condition (condition of the ground, density, height and nature of the forage).

• Reduce ground speed when working in dense or flattened forage and when mowing around a curve.

• It is not possible to mow backwards with the mower unit. Raise the mower unit when reversing.

Operation • Do not mow on rocky ground!

DANGER! When mowing with a tractor without a cab, or with open cab windows and doors, wear ear protection.

Remove the ear muffs when driving on the road.

ATTENTION! When mowing with the front mower unit, the suction sieves and coolers of the tractor engine can become very contaminated.

The tractor engine and the hydraulic unit can overheat and be damaged.

– The suction sieves and coolers of the tractor should be cleaned several times per day!

DANGER! To rectify blockages or to remove foreign bodies, switch off the PTO shaft drive, switch off the tractor engine and only when the mower discs have come to a complete standstill, leave the tractor.

Recommendations for environmental protection A simple change in the way we normally mow can help to reduce the loss of wild animals.

At the same time, the quality of the mowed crop is increased.

ENVIRONMENT! If we mow from the outside inwards, wild animals have hardly any chance of escape!

– Mow from the inside outwards.

Operation Drive to the middle of the lot and mow from the inside outwards.

The centre can be mowed if there is enough room to turn.

Wild animals thus have the chance of escaping outwards.

(Fig. 13)
