Checking and adjusting the cutting
deck's ground pressure
In order to achieve the best mowing result the cutting deck
should follow the ground without touching it too heavily.
Pressure is adjusted using a screw and spring on each side
of the Rider.
1 Check the air pressure in the tyres, 200 kPa/ 2 bar/ 30 PSI
at the front and 160 kPa/ 1.6 bar/ 24 PSI at the rear.
2 Place the Rider on a flat surface.
3 Lower the cutting deck to the mowing position.
4 Place a set of bathroom scales under the cutting deck's
frame (on the front edge) so that the cutting deck rests on
the scales. If necessary a block can be placed between
the frame and the scales so that the anti-scalp rollers do
not support any weight.
5 Adjust the cutting deck's ground pressure by screwing the
adjuster screws, which are located behind the front
wheels on both sides, in or out. The ground pressure
should be between 12 and 15 kg (26.5-33 lbs) and the
springs tensioned equally.
Checking the parallelism of the
cutting deck
Check the cutting deck's parallelism as follows:
1 Check the air pressure in the tyres
2 Place the Rider on a flat surface.
3 Lower the cutting deck to the mowing position. The cutting
height must be at lowest position, position 1.
4 Measure the distance between the ground and the front
and back edges of the unit's cover. The cutting deck
should have a slight slant, with the rear edge 2-4 mm (1/
8") higher than the front edge.

MAINTENANCE
Adjusting the parallelism of the
cutting deck
1 Remove the front cover and the right-hand wing cover,
see "Dismantling the Rider covers" on page 23.
2 Loosen the nuts on the parallel strut.
3 Screw out (extend) the strut to raise the rear edge of the
cover.
Screw in (shorten) the strut to lower the rear edge of the
cover.
4 Tighten the nuts after adjustment.
5 The parallelism of the cutting deck should be checked
again after the adjustment has been made.
6 Attach the front cover and the right-hand wing cover.

The cutting deck's service position

In order to provide good accessibility for cleaning, repair and
servicing, the cutting deck can be set in the service position.
The service position means that the cutting deck is raised and
locked in the vertical position.

Placing in the service position

1 Place the machine so it is flat. Engage the parking brake.
2 Make sure the cutting deck is in the raised position.
