CUTTING HEIGHT _________________________________________________________
Cutting height for decks can be adjusted from 1 to 5-1/2
in. (25-125 mm) in 1/2 in. (13 mm) increments. 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.
1.
Park the mower on a flat, level surface. Raise the
decks until the caster wheels are raised off the
ground enough so caster wheels can be removed
from deck. Place blocks under decks so they are
supported on all sides.
To remove inside front caster from side decks, raise
the decks to their full upright position and lock in the
transport position.
2.
Figure 4E shows the height adjustment decal for the
casters.
Column 1 - Height of cut
Column 2 - Mount Location
Column 3 - Arrangement of spacers
Adjust spacers in quantity listed. Store extra spacers
on top of spindle. If necessary, reposition wheel
mount in holes indicated for height of cut.
IMPORTANT:
Do not reposition the thin thrust
washers (1/16 in.) and leveling washers (1/8 in.) on
the spindle. These washers should remain in the
same position and quantity they were originally
installed. They need only be repositioned if needed
to level new casters or decks, Section 4.2
3.
To adjust rear gauge wheels on front deck, refer to
Figure 4F. Raise front deck approximately 12 in. and
support underneath with blocks. Lower deck so it is
completely resting on blocks
4.
Remove pin from rear gauge wheel yoke and
reposition in bracket for desired height of cut. When
setting cutting height at 5-1/2 in., gauge wheel must
be repositioned in arm. Follow wheel mounting
instructions on decal, Figure 4F.

Tire pressure
Check air pressure in caster tires, while tires are cool.
Maintain air pressure between 20-25 psi (138-173 kPa)
to improve accuracy of cutting height.
Note
:
It is important to keep inflation pressures on all
caster and gauge tires equal, within the range specified,
to ensure an accurate, level cut.
WARNING
To prevent serious injury, lower deck until it is
resting completely on the supports. This will
prevent it from accidentally lowering while making
adjustments. Disengage all drives, engage
parking brake, stop engine, and remove ignition
key.
