3.14 CUTTING HEIGHT__________________________________________________________________________
Level the front mower before setting the cutting height for the first
time. Do not remove the cutting units from the mower to change
cutting height.
Cutting height for decks can be adjusted from 1 to 5-1/2 in. (25-140
mm) in 1/2 in. (13 mm) increments. Actual cutting height may vary
somewhat from the heights given depending on turf conditions, tire
variances and other factors.
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.
2. Figure 3M shows the height adjustment decal for the casters.

3. Adjust spacers in quantity listed. Store extra spacers on top of
spindle. Always leave one thin spacer above and below caster
arm.
4. For cutting heights 3 in. (76 mm) and below, caster arms should
be assembled to upper set of holes (A). For cutting heights
above 3 in. (76 mm), caster arms should be assembled to lower
set of holes (B).

NOTICE
When cutting undulating areas, lower cutting heights may cause
scalping. Adjust height accordingly to prevent turf damage.
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.
!
NOTICE
After setting cutting height, fully lower cutting units onto a flat,
hard surface, stop engine, and measure the distance from the
blade tips to the ground. If the distance is different from the
desired cutting height, make adjustments as necessary. Cut in a
small test area and make any final adjustments for desired turf
appearance.
