9 ADJUSTMENTS
9.3 HEIGHT OF CUT
Cutting height for decks can be adjusted from 25-
115mm. Actual cutting height may vary somewhat
from the heights given depending on turf conditions
and other factors.
Note: When cutting undulating areas, lower cutting
heights may cause scalping. Adjust height
accordingly to prevent turf damage.
To Change the Height of Cut
1. Park the tractor on a flat, level surface. Fully
lower cutting unit. Place blocks under deck so
it is supported on all sides.
2. Refer to the chart provided for desired cutting
height.
3. Caster Mount - The caster wheel mounting
brackets may be attached to deck mounting
plates at two different points. Select either
position 1 or 2 for the two height of cut ranges.
4. Caster spacers - Spacers may be moved from
below to above the pivot spindle to make
relatively small changes in the height of cut.
a) Remove cotter pin and ring from the top of the
caster yoke shaft, and remove the yoke and
wheel completely from pivot spindle mounting.
b) Select the spacers needed and place on the
caster yoke shaft.
c) Reinsert the caster yoke shaft into the pivot
spindle mounting.
d) Place the remaining spacers on the caster yoke
shaft above pivot spindle mounting. Replace
the cotter pin and ring.
5. Fit pin to plate H to give the required height of
cut.
For best performance it is recommended not to cut of
more than 1/3 of the grasses length in one cut. This is
particularly important when using a mulching deck.
Adjust forward speed in consideration of the grass
conditions, the performance lamp is a guide to
optimise cutting performance.
