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).
•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 51.
6.Fit the front cover.
IMPORTANT INFORMATION
When changing the cutting unit, you must readjust the parallelism and cutting height.
Parallelism
1.Loosen the two nuts on the strut.
2.Measure the distance between the ground and the front and back edges of the unit’s cover.
3.Place a spanner over the bevel in the middle of the strut and tighten so that the cutting unit’s rear edge is
4.Check the measurement.
5.Then tighten the two nuts on the strut.
