Check the tyre pressures (60 kPa).
Place a set of bathroom scales under the mower
deck's frame (front edge) so that the deck rests on
the scales.
Adjust the mowing deck's ground pressure with the
adjuster nuts placed behind the front wheels on
both sides of the ride-on mower. The ground

Adjusting FR 13
Check the tyre pressures (60 kPa).
Place the ride-on mower on an even surface and
measure the distance between the ground and the
edge of the deck, at the front and rear of the cover.
The cutting unit should slope forwards slightly so
that the rear edge is 2-4 mm higher than the front
edge.
• Remove the front cover and the right-hand
fender.
• Vertical adjustment of the mowing deck is made
with the adjuster nuts on the back edge of the lift-
strut.
• Raise the mowing deck at the front edge by
shortening the lift-strut.
Lower the mowing deck at the front edge by
lengthening the lift-strut.
• Tighten the nuts against each other after the
adjustment.
• On completion of the adjustment, the deck's
parallelism should be re-checked.
• Fit the right-hand fender and the front cover.
