Checking and adjustment of the cutting
unit’s ground pressure
To achieve the best cutting results the cutting unit
should follow the underlying surface without pres-
sing too hard against it.
The pressure is adjusted with a screw on each side
of the machine.
1. Check the air pressure in the tyres 60 kPa
(0.6 kp/cm
2
/8.5 PSI).
2. Place the Rider on a flat surface.
3. Put the lifting lever in the mowing position.
4. Place a set of bathroom scales under the cutting
unit’s frame (front edge) so that it rests on the
scales. If necessary a block can be placed
between the frame and scales so that the
support wheels do not bear any weight.
5. Adjust the unit’s ground pressure by screwing in
or out the adjusting screws located behind the
front wheels on both sides.
The ground pressure should be between
12 and 15 kg (26.5-33 lb).
Checking the cutting unit’s parallelism
Check the parallelism of the cutting unit as follows:
1. Check the air pressure in the tyres 60 kPa
(0.6 kp/cm
2
/8.5 PSI).
2. Place the machine on a level surface.
3. Put the lifting lever in the mowing position.
4. Measure the distance between the ground and
the front and rear edges of the cutting unit hood.
The cutting unit should slope forwards slightly so
that the rear edge is 2-4 mm (1/8") higher than
the front edge.
