The Forward Pitch Of The Mower
Blades
(Figure 9)
• 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 point forward.
The Pitch Of The Mower Blades From
Side-To-Side
(Figure 10)
• 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 point left and
right.
Adjusting The Mower Deck To Adjust
Mower Blade Height And Pitch
(Figure 11)
NOTE: Adjusting the mower deck will adjust
the 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 12)
1. Block mower blades to prevent rotation.
2. Remove mounting hardware and mower
blades from spindles.
Install
(Figure 12)
1. Install mower blades on spindles with
mounting hardware.
2. Torque 5/8-inch nut to 92 to 130 lbf-ft
(125 to 176 N•m).
