6.3.7 MOWING DECK - CHECKING THE DRIVE PULLEY OF THE DECK
Before every use of the machine, check the
fastening bolt of the pulley. The bolt should
be pulled tight with a torque of 80 Nm.
The pulley is accessible after lowering the
mowing deck to the lowest position.
6.3.8 CHECKING AND ADJUSTING THE DRIVE BELT
When working on various parts of the machine's drive always turn off the engine and take
the key out of the ignition.
Regularly check the wear and tension of V-belts and
the tensioning mechanism.
The drive V-belts (travel and mowing) are automatically
tensioned by a spring and a pulley. Before starting
work or at least after every 50 hours of operation
check the wear on the V-belts and the working order
of the tensioning mechanism.
Adjust the position of the drive belt tensioning pulley
using adjusting nuts.
Distance A = 60±2 mm.
Distance B = 78 mm (set the mowing deck elevation
adjustment lever to the second last position)
When attaching a new belt pay special attention when working with the machine because
the belt is not yet sufficiently run-in.
6.3.9 REPLACING BELTS
Replacing drive belts is a relatively demanding operation, which needs to performed by an authorised
service centre.
6.3.10 ADJUSTING THE TRAVEL DIRECTION LEVER
If the travel direction lever returns to the "N" position on its own, it is necessary to adjust it. Have this
task performed at a specialised service centre.
6.3.11 REPLACING WHEELS
Before replacing one of the wheels, park the tractor on a horizontal and rigid surface, turn off the
engine and remove the key from the ignition. Secure the machine against movement. Do not replace
the wheel if the machine is not sufficiently secured in the elevated position!
