Unscrew two nuts and washer from the drive belt tensioning mechanism on the mowing
deck. This will release the spring and the belt. Remove the belt from the pulley wheels.
Set the correct distances A, B and C by adjusting the bolts in the front and rear part of the
mowing deck.
When adjusting distance C it is recommended to place something under both sides of the
mowing deck cover, use underlays of the same size (e.g. wooden boards, etc.) and use them
to level the deck so that the distance from the ground is the same on both the left and right
hand side.
After setting the correct distances of the mowing deck, pull tight all loose nuts and bolts using a torque
of 55 - 65 Nm. After putting on the mowing deck drive belt and the tensioning mechanism, tighten the
nuts so that the length of the tensioning spring is 85 ± 1 mm. Then reattach the mowing mechanism
cover.
If you are not certain about this procedure, have it performed by a service centre.
6.3.8 MOWING DECK - CHECKING AND ADJUSTING THE BELT
Because of the demands placed on it, the tension of mowing deck belt drive declines over time and it is
necessary to tension it. The belt is tensioned using a tensioning mechanism with a spring and is correctly
tensioned at the moment when 4 kPa of force is applied at the mid-distance between the pulley wheels,
and the belt bends out by approximately 0.5 cm.
To measure force you can use a standard mechanical dynamometer available in stores selling
such products.
Release the safety pins on the mowing deck cover on the right side by sliding a screwdriver
into the groove of the pin and turning it anticlockwise. Take the cover off the machine.
Tighten the tensioning bolt nut so that the length of the tensioning spring is 85 ± 1 mm.
Reattach the mowing mechanism cover.
6.3.9 MOWING MECHANISM - REMOVAL
Set the mowing mechanism to the lowest position by setting the adjustment lever to position 1.
Take off the mowing deck cover (
Slightly raise the grass removal tube (1) and slide it off the two pins welded to the frame
of the mowing mechanism. Then either slide the tube 10 cm to the rear (2) and secure it,
or completely remove it from the machine through the rear plate.
Unscrew two nuts and washer from the drive belt tensioning mechanism on the mowing
deck. This will release the spring and the belt. Remove the belt from the pulley wheels.
Turn the pulley wheel assembly so that you get access to the bolts on the rear side of the
mowing deck. Unscrew the bolts.
It is not necessary to remove the bolts on the front side of the mowing deck, it is enough
to unhook the deck from the holding bracket.
Slowly pull the mowing deck out of the machine.
