Checking And Adjusting The Cutting Unit's Ground Pressure; Cutting Height - Husqvarna Rider Pro 18 AWD Operator's Manual

Checking and Adjusting the Cutting
Unit's Ground Pressure
In order to achieve the best mowing result the
cutting unit should follow the ground without
touching it too heavily. The pressure is adjusted
using a screw on each side of the Rider.
1. Check the air pressure in the tyres 60 kPa /
0.6 bar / 9 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 (on the front edge) so that
the unit 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 unit'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 lb).
IMPORTANT INFORMATION
When changing the cutting unit, you must
readjust the parallelism and cutting height.

Cutting Height

1. Place the Rider on a flat surface.
2. Loosen the nut on the height adjustment strut.
3. Measure the distance between the ground and
cutting unit's edge at the front of the cover. The
cutting unit should have a slight slant, with the
rear edge 2-4 mm (1/8") higher than the front
edge.
The distance between the front edge and the
ground should be:
• 40 mm for Combi 94 and Combi 103
• 35 mm for Combi 112.
4. Tighten the nut.
5. Check that the parallelism has not changed. If
so, the parallelism must be readjusted.
6. Check and if necessary adjust the cutting unit's
ground pressure.
7. Fit the front cover.
