Checking The Cutting Unit's Parallelism; Adjusting The Parallelism Of The Cutting Unit - Husqvarna Rider Pro 15 Operator's Manual

Checking the cutting unit's parallelism

Check the parallelism of the cutting unit as follows:
1. Place the machine on a level surface.
2. 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 higher than the
front edge.
Adjusting the parallelism of the cutting
unit
1. Remove the front hood and right-hand fender,
as described on page 19.
2. Undo the nuts on the lift strut.
3. Unscrew the strut (anticlockwise) to lower the
rear edge of the hood.
Screw the strut in (clockwise) to raise the rear
edge of the hood.
4. Tighten the nuts after adjustment.
5. On completion of the adjustment the unit's
parallelism should be re-checked.
6. Fit the right-hand fender and the front hood.
Adjusting the cutting height
1. Loosen the nut on the height adjustment strut.
2. Adjust so that the distance between the stop for
lowest height setting and the protective frame is
5 mm.
3. Tighten the nut.
4. Recheck that the parallelism has not changed. If
so, the parallelism must be readjusted.
5. Check and if necessary adjust the cutting unit's
ground pressure, see "Checking and adjusting
of the cutting unit's ground pressure".
6. Fit the nose cover.
IMPORTANT INFORMATION
The parallelism and height must be
adjusted again when changing the cutting
unit.
