LEVELLING AND ADJUSTING
PITCH OF MOWER DECK
NOTE: Adjust on a level surface, with the
tires inflated to the correct air pressure (see
SPECIFICATIONS on page 30).
There are three measurements required to
level and adjust the pitch of the mower deck.
1. The distance from the mower blades to
the ground.
2. The forward pitch of the mower blades.
3. The pitch of the mower blades from
side-to-side.
The Distance From The Mower
Blades To The Ground (Figure 13):
In the lowest cutting position should be
1-1/2 in. + 1/4 in. (3.8 cm +0.64 cm).
In the highest cutting position should be
4-1/2 in. + 1/4 in. (11.4 cm + 0.64 cm).

The Forward Pitch Of The Mower
Blades (Figure 14):

NOTE: This measurement must be taken
when the mower blades ends are facing
forward.

The Pitch Of The Mower Blades From

Should be within 1/4 in. (6.35 mm) as
measured on each side of the mower
deck.
NOTE: This measurement must be taken
when the mower blade ends are
perpendicular (at a right angle) to the frame
of the unit.
