6.3.7 MOWING DECK - INSPECTION AND BALANCING
To achieve the best mowing results the mowing deck must be set at the correct mowing height and both sides of the deck must be
level.
Before carrying the adjustment:
► Place the mower on an optimally even surface, inflate all the tyres to the prescribed pressure (80 - 140 kPa, ± 10 kPa
difference between the individual tyres) and secure the entire mower against movement (e.g. using a suitable wedge, etc.).
► Move the mowing deck elevation adjustment lever to position 1.
The mowing deck is equipped with plastic covers which prevent hand access to moving parts and to the mower drive
parts of the mower.
The covers can be very quickly and easily removed using the quick coupling pins on the sides of the covers. Slide
a screwdriver into the pin groove and turn it anticlockwise. Then take the cover off the mower.
► Distance A is the front edge of the mowing deck in the travel direction and it must be 30-34 mm above the ground.
Check it on both sides of the mowing deck. If the height is different, loosen the lock nuts (2) on the respective draw
rod (1) and adjust the height by the turning nuts (3). After setting the correct height, do not forget to tighten the lock
nuts (2).
6.3.7a
► Distance B is the rear edge of the mowing deck in the travel direction and it should be 28-30 mm above the ground,
i.e. the rear edge must be at least 5 mm higher than the front edge. If the height is different, adjust it by loosening
nuts (4), setting the edge to the correct height and tightening the nuts with a torque of 55 – 65 Nm.
If you are not certain about this procedure, have it performed by a service centre.
6.3.8 MOWING DECK - CHECKING AND ADJUSTING THE V-BELT
Because of the demands placed on it, the tension of the mowing deck drive belt (1) declines over time and it is
necessary to tension this belt. The belt is tensioned using bolts and a spring.
► Set the mowing deck to position 1.
6.3.8a
► Using a suitable wrench, turn nut (2) so that spring (3) is tensioned to a value of 150±1 mm.

6.3.10 MOWING DECK - REMOVING IT FROM THE MACHINE
► Set the mowing deck to the highest position by moving the elevation adjustment lever to position 7.
► Using an appropriate wrench, turn nut (1) so that the tension on the spring (2) is completely released. Then remove
6.3.10a
the belt (1) from the belt pulley of the electromagnetic engine transmission.
► Slide the spring pins (4) from both the rear mowing deck suspension shaft pins (5). Screw out the nut (6) from the
front shaft pin and pull out the shaft pin (7). Using pliers, slide out both pins (5). For the the mowing deck mulching
6.3.10b
option, first remove the part of the mulching flap lever that extends above the floor of the mower.
► Slowly pull out the mowing deck to one side of the mower.
6.3.10c
6.3.11 MAINTENANCE OF STEERING
Regularly check that there is not excessive looseness between the cogged steering segment and the steering wheel
pinion. If higher looseness is identified, it is necessary to limit it. Procedure for limiting (adjusting) looseness:
► Lift the hood.
► Loosen two nuts M12 (1) on the bolt of the eccentric.
6.3.11
► Place a suitable wrench on to the hexagon of the eccentric (2) and turn it until looseness is limited to a minimum.
► Tighten both nuts M12 (1) using a torque of 35 - 45 Nm.
Neglecting this maintenance may result in damage to steering components.
