Adjusting the Mower Deck Front-to-
Rear Pitch
Changing the front-to-rear pitch is done by adjusting the
front height-of-cut posts.
1. To raise the front of the deck, loosen the jam nut
on the lower end of the deck hanger pin assembly.
Rotate the front pin clockwise (Fig. 1387).
2. To lower the front of the deck, loosen the jam nut
on the lower end of the deck hanger pin assembly.
Rotate the front pin counter-clockwise (Fig. 000).
3. Position the mower blades in the front-to-rear ori-
entation. Measure at the AA and BB locations (Fig.
1385 and Fig. 1386) from a level surface to the
cutting edge of the blade tips.
4. Check the side-to-side leveling of the cutting unit.
Refer to Checking the Mower Deck Side-to-Side
Height.
5. Tighten the jam nuts (Fig. 1387).
1. Adjust the rear tire pressure to 12-14 psi (83-97kPa).
2. Position the mower blades in the side-to-side orien-
tation. Measure at the C and D locations from a level
surface to the cutting edge of the blade tips (Fig.
1388 and for 36” mower decks use Fig. 1389).
3. The difference between the measurements at the C
and D locations should be no more than 1/4” (6mm).
4. If the side-to-side pitch is not correct, proceed to
Adjusting the Mower Deck Side-to-Side Height.
