Adjusting The Mower Deck To Adjust
Mower Blade Height And Pitch
(Figure 15)
NOTICE: 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.
NOTICE: 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.
