CUTTING HEIGHT _________________________________________________________

Cutting height for decks can be adjusted from 1 to 4 in.
(25-100 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 tractor 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 prevent serious injury, lower deck until it is
resting completely on the supports. This will
prevent it from accidentally lowering while making
adjustments. Disengage
parking brake, stop engine and remove ignition
key.
2. Figure 3G shows the height adjustment decal for
the casters.

3. To adjust rear gauge wheels on front deck refer to
Figure 3H. Raise wing decks approximately 12" and
support underneath with blocks. Lower deck so it is
completely resting on blocks
4. Remove pin from rear gauge wheel yoke and

Gauge Wheel Adjustment for Wing Decks
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.
