The Forward Pitch Of The Mower
Blades
(Figure 13)
• Front tip of blades should be 0 –
0.635 cm (0 – 1/4") lower than the rear
of the blades.
NOTE: This measurement must be taken
when the mower blade ends point forward.
The Pitch Of The Mower Blades From
Side To Side
(Figure 14)
• Should be within 0 – 0.635 cm
(0 – 1/4") 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 15)
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.
Adjust Trunnions:
1. Using an adjustable or open ended
wrench tighten or loosen the lock nut on
top.
NOTE: To avoid over-adjustment note which
nuts have been adjusted and the amount
each has been loosened or tightened.
2. Using the same tool, tighten the bottom
hex nut to raise the deck OR loosen the
bottom hex nut to lower the deck.
3. Tighten the lock nut on top to secure the
link in the desired location.
4. Repeat step 1 as needed until all three
measurements (a, b, and c) are within
the tolerances specified.
