Adjusting the Cutting Height, Parallelism
and Ground Pressure
When a new cutting unit is attached, you need to adjust
the cutting height, parallelism and ground pressure.
Adjustment must be made in the stated order.
Starting position:
• Check the air pressure in the tyres 60 kPa / 0.6 bar /
9 PSI.
• The cutting unit shall be lowered onto a flat surface.
• The height adjustment lever shall be set to the
lowest cutting height.
Cutting Height
1. Loosen the nut on the height adjustment strut.
2. Measure the distance between the ground and the
front edges of the cover.
The distance between front edge and the ground
must be 35 mm.
3. Tighten the nut.
4. Check and align the parallelism if necessary.
5. Check and adjust the cutting unit's ground
pressure if necessary according to "Ground
pressure" on page 49.
