Adjusting The Mower Deck To Adjust Mower

Blade Height And Pitch (Figure 8):

If the mower blade height and pitch cannot be adjusted

to the measurements indicates, it will be necessary to

adjust the position of the mower deck.

NOTE: There are two ways to adjust the position of the

mower deck:

• By adjusting the trunnions that attach the mower

deck to the deck lift arm.

• By adjusting the bolt position on the mower deck

along with adjusting the trunnions.

1. Adjust the trunnions (1) 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. If the measurements cannot be met by adjusting

the trunnions:

A. Move the bolt(s) (2) up or down in the slot in the

deck link (3).

B. Adjust the trunnion(s) (1) as needed.

C. Retake the three measurements required to level

and adjust the pitch of the mower deck.

3. Repeat steps 1 and 2 as needed until all three

measurements are within the tolerances specified.

the unit to face a wall for safety.

5. Disconnect wireform link (3) that connects the

steering handle to the transmission.

6. Remove the steering rod (2).

7. Start engine.

If the rear wheels do not rotate, go to step 12.

If the wheels rotate, adjust neutral at the

transmission; go to step 8.
