4.1

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

Check the mower unit every time it will be used 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 at every change of cutting blades according to regulations specified by the manufacturer and replace if necessary!

It is most of all important to check the degree to which the blade holding bolt has been worn down on its inner radius by the blade. It must be replaced by a new unused blade holding bolt at the latest when a groove depth of 3 mm has been reached, that is a reduction of the inner radius by 3 mm.

The riveting on the blade bolt in the knife holder as well as the wear on the knife holder on the outer edge are to be checked. All knife holders on the cutting disc, knife must be replaced by new knife holders if necessary.

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.

This is why one should not step between the tractor and the mower unit. The swivelling process must take place with the mower unit in a horizontal condition.

The glide discs must be in contact with the ground before putting into operation and while working!

Stones and similar objects can be thrown out even when the mower unit is being used correctly. Therefore, no-one should be in the danger zone.

Special care is required when working near roads and buildings!

The working tools cab run on after switching off the drive. Do not approach them until they have stopped.

If an obstacle is run over, stop the mower unit immediately and check for damage!

4.2

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 implement 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 implement!

Only operate the machine when all guards are fitted and in the correct position!

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

Keep clear of the swivelling range of the operating machine.

Watch for pinch and shear points on parts that are operated, for instance by hydraulics!

BA DISCO 3450 / 3050 / 3050 C / 2650 / 2650 C - 293 857.5

Safety Instructions Before leaving the tractor, ensure that the machine cannot roll away! Lower any mounted implements fully to the ground! Switch off the engine and remove the ignition key.

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

ATTACHED MACHINES

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!

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

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

Before attaching the machines to 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!

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!

When attaching mounted machines to the 3-point linkage, the linkage categories of tractor and machine must correspond or the necessary modifications must be performed!

Always ensure that no-one is in the danger zone of the machine before switching on the p.t.o. shaft!

A risk of injury due to crushing or shearing exists in the vicinity 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 wen the machine is in the transport position!

During road transport with the machine raised, the control lever must be locked to prevent unintentional lowering of the machine!

MACHINES AS TRAILORS Secure the machine to prevent it from rolling away!

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

When hitching the machine at 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 disengage the PTO shaft, stop the engine and remove the main switch key before attaching or detaching the universal drive shaft!

When universal drive shafts with overload or freewheeling clutches are used which are not protected by the tractor's guard, the overload or freewheeling clutches have to be installed next to the machine.

293 857.5 - BA DISCO 3450 / 3050 / 3050 C / 2650 / 2650 C

Never engage the PTO shaft while the engine is stopped!

When operating the PTO shaft no-one must ever 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!

Danger: rotating masses run on after the PTO has been disengaged! 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 with a switched off p.t.o. shaft, switched off engine and the ignition key removed!

Whenever 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 the protective guard must be pushed on to the PTO stub shaft!

In case of damage, the defective parts must immediately be repaired before working with the machine!

HYDRAULIC SYSTEM The hydraulic system is under high pressure!

When attaching hydraulic cylinders and motors, take note if the prescribed connection of the hydraulic hoses!

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!

4.3

Safety Instructions When making hydraulic function connections between the tractor and machine, the female couplings and pins must be marked so that false operation is impossible! Mixing the coupling reserves the functions (e.g. raise/lower) – Safety hazard!

Always disconnect the power supply before working on the electrical system!

Guards and protecting devices that are subjects to wear must be checked at regular intervals and replaced in good time!

Check hydraulic lines at regular intervals, and replace them in the case of damage or ageing!

Replaced hydraulic lines must correspond to the technical requirements of the equipment manufacturer!

Note!

On the DISCO 3450 the safety frame (5) can be swung upwards on the right hand side if necessary. This reduces the transport height.

5 (Fig. 11)

11

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

In the majority of applications the cutting height can be achieved by setting the tilt angle (Z) to about 2 - 4°.

(Fig. 12)

12

7.4

BA DISCO 3450 / 3050 / 3050 C / 2650 / 2650 C - 293 857.5

Operation Achieve this by lengthening or shortening the upper link until the desired cutting height has been achieved.

(Fig. 13)

Attention!

A smaller cutting height produces greater wear on the cutting discs and blades.

13 Danger!

Reduce the tilt angle (Z) of the machine on uneven ground. This produces a greater cutting height and reduces any danger of propelling foreign objects forwards.

Collision protection 3 4

If the tractor drives up to an obstacle the overload protection feature (1) triggers and the mower head can swing away to the rear.

2

If you collide with an obstacle turn the PTO off immediately and turn the tractor engine off. Check the cutterbar for damage.

1

14

The mower unit must be raised to bring it back into its working position and the security system against driving off will engage again after short jerky resetting of the tractor.

It may be necessary to readjust the rubber spring (2) if the security system against driving off is triggered often.

Release the lock nut (3) and rotate the nut (4) through one revolution and re-tighten the lock nut (3).

Note!

One rotation of the nut (4) already gives the largest effect. It is therefore best to check the function of the collision protection before re-tensioning!

Before using the machine for the first time, check the function of the collision protection.

Two spanners (SW 24) will be required for re-tensioning, and so these should be taken along.

Operation Mowing

Attention!

Keep the terrain to mow free of foreign matter.

Danger!

Before operation and after driving into an obstacle check the mower unit for damaged, missing or worn mower blades and check the mower blade fasteners.

Check that the mower blades are correctly seated.

•

Lower the mower unit to the working position.

During work, the hydraulic control lever for the tractor hydraulic connection must be in the Float (free gear) position.

15

•

Before entering the field to be mowed, turn on the tractor PTO shaft and slowly accelerate to the maximum permitted PTO shaft speed . 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 in reverse with the mower unit. Raise the mower unit when reversing.

Do not mow on rocky ground!

Operation

Danger!

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

Remove the ear protection when driving on the road.

Danger!

To remove blockages or to remove foreign bodies switch the PTO off, stop the tractor engine and only leave the tractor cab when the mower drum has come to a complete standstill.

If the angle (W) of the mower head exceeds 20° upwards or downwards after long use it is recommended to reduce the amount of oil in the mower head by 0.25 litres in order to prevent overheating .

(Fig. 20, 21) The mower heads should also raided to a horizontal position every 15 minutes every few minutes.

Danger!

After extended operation, the mower cutter bar can reach temperatures up to around 80° C.

20

Do not touch the bar with your hand - danger of burning!.

Difficult operating conditions Take special care when working under difficult operating conditions or on uneven ground. To prevent foreign bodies from being hurled around, observe the following points: •

Increase the cutting height by lengthening the upper link. The cutterbar should be inclined slightly forwards up to maximum horizontal.

•

Reduce ground speed.

•

Check that the mower blades can rotate around the cutter retaining bolt.

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! â&#x20AC;&#x201C; Mow from the inside outwards.

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. 22)
