Adjusting The Mower Deck To Adjust

Mower Blade Height And Pitch

(Figure 11)

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.
