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 25).
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 12):
• In the lowest cutting position should be
1-1/2-in. + 1/4 in. (1.3 cm + 0.64 cm).
• In the highest cutting position should be
be 4-1/2-in. + 1/4 in. (5.1 cm + 0.64 cm).
The Forward Pitch Of The Mower
Blades (Figure 13):
• Should be 0.0 in. (0.0 mm) to 1/4 in.
(6.35 mm) pitched forward.
NOTE: This measurement must be taken
when the mower blades ends are facing
forward.
The Pitch Of The Mower Blades From
Side-To-Side (Figure 14):
• 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 blades ends are
perpendicular (at a right angle) to the frame
of the unit.
