6.3.7 Mowing deck – checking and adjusting the height
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 machine on an optimally even surface, inflate all the tyres to the prescribed pressure
(80 -150 Kpa, ± 10 Kpa difference between the individual tyres) and secure the entire machine
against movement (e.g. using a suitable wedge, etc.).
} Move the mowing deck elevation adjustment lever to the lowest position.
When checking and adjusting, proceed as follows:
For mowing decks with a mowing coverage of 92 cm and 110 cm:-
} Check the difference between the height of the front edge A and the height of the rear
edge B. The measured difference must be in the range 5-10 mm and must be the
same on both sides of the front edge.
} If the height difference is different, loosen the lock nuts (1) on both sides of the machine
and adjust the height by turning nut (2). Do not forget to tighten the lock nuts (1).
Only for riding mowers with a mowing coverage of 110 cm and 132 cm:
} Check the height of the rear edge B. Place an appropriate support (3) under the front
edge of the deck and measure the height B. The difference between height A and height
B must be in the range of 3-6 mm
} If the measure B is different, adjust its height by loosening bolts (4) on both sides of
the deck and set the deck to the correct height. Tighten the bolts (4)
6.3.8 Mowing deck – adjusting the control force of the mowing deck elevation lever
In the event that more force is required to lift the mowing deck than usual, it is possible
to adjust the control force of the elevation lever (1). Proceed as follows:
} Turn nut (2) to set spring (3) to the length:
- 280 mm for the mowing deck with a mowing coverage of 92 mm (GC 92)
- 300 mm for the mowing deck with a mowing coverage of 110 mm (GC 110 and
GC 132)
It is necessary to set the spring on both sides of the machine!
6.3.9 Mowing deck - checking the drive belt pulley of the deck
The mowing deck drive belt pulley and belt are protected under a plastic cover. For the
purpose of cleaning, inspection and adjustment, this cover can be removed by unscrewing
6.3.9a the five screws on its sides.
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.
6.3.9b
The belt pulley is accessible after lowering the mowing deck to the lowest position.
6.3.10 Mowing deck - checking and adjusting the blade drive belts
When working on various parts of the machine's drive always turn off the engine and
take the key out of the ignition.
Í Machine GC 92 (mowing deck with a mowing coverage of 92 cm):
The drive for the mowing deck blades is provided by the belt pulley (2) via an
electromagnetic transmission (1) and belt pulley (3). Because of the demands placed on
it, the tension belt declines over time and it is necessary to re-tension it.
} Move the mowing deck elevation adjustment lever to the lowest position.
} Tension belt (2) using the tensioning draw bar with nut (4) so that the spring has
a length of 80 mm.
