3. Wheel drive
Warning!
Secure the tractor against rolling away!
It causes crushing injuries.
Never reach into the crushing danger zone if parts can still move there.
The wheel drive is driven by a V-belt. These are very robust and only need to be exchanged if
they are defective. The repair should be carried by an authorised
workshop. Each V-belt
should be inspected after ½ hour and adjusted if necessary.
Tensioning the V-belt
Please note that new V-belts must first be run in and therefore is it necessary to adjust them fol-
lowing a short period of use.
To tension the V-belt:
•
Switch off the engine – place the engine switch in the ‘ON’ position, remove the ignition
key (if there is one) or pull off the spark plug cap.
•
Secure the tractor against rolling away.
•
Measure the length of the relaxed tension spring on the Bowden cable of the wheel drive.
•
Now depress the tensioning lever and measure the length of the stretched tension spring -
(see fig. 20).
•
The difference in length between the relaxed and the stretched tension spring should be 5 - 8
mm.
•
If this is not the case, you must change this distance with the help of the adjusting screw.
•
Loosen the lock nut of the appropriate adjusting screw and turn it until the length of the ten-
sion spring is correct. The lock nut must be tightened again afterwards.
The correct tension can be adjusted on the wheel drive tensioning lever. If the V-belt slips or no
longer grips, the tension can be adjusted using the adjusting screw. You must unscrew the adjust-
ing screw until the wheel drive works properly again.
