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.
