The Forward Pitch Of The Mower Blades
(Figure 11):
• 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 12):
• 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.
Adjusting The Mower Deck To Adjust Mower Blade
Height And Pitch (Figure 13):
NOTE: Adjusting the mower deck will adjust he height and
pitch of the mower blades.
1. Adjust the trunnions first and re-take the three
measurements required to level and adjust the pitch of
the mower deck. These measurements are:
a. The distance from the mower blades to the ground.
b. The forward pitch of the mower blades.
c. The pitch of the mower blades from side-to-side.
2. Repeat step 1 as needed until all three measurements
are within the tolerances specified.
REPLACING MOWER BLADE
Remove (Figure 14)
1. Block mower blades to prevent rotation.
2. Remove mounting hardware and mower blades from
mower deck.
Install (Figure 14)
1. Install mower blades on mower deck with mounting
hardware.
