Checking Carrier Frame Side–to–Side
1. Stop the engine, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Adjust the tire pressure in all tires to specifications on
page 28.
3. Measure carrier frame height at location “A” (Fig. 48).
4. Measure carrier frame height at location “B” (Fig. 48).
5. If the carrier frame height is not the same move
spacers from top or bottom of caster wheel, to make it
level. The tire pressure may also be adjusted slightly to
make it level.

Checking the Deck
Front-to-Rear Pitch
1. Check the tire pressure on both deck and traction unit.
2. Position one blade front-to-rear (Fig. 49). Measure at
“C” and “D” locations (Fig. 49) from a level surface to
the cutting edge of the blade tips (Fig. 50).
3. The mower blade should be 1/4 in. (6 mm) lower in
front “C” than in the rear “D”. Rotate blades and
repeat for other blades. If it is not correct, proceed to
Changing the Deck Front–to–Rear Pitch.

Changing the Deck
Front-to-Rear Pitch
Changing the front–to–rear pitch is done by adjusting the
front height–of–cut posts.
Changing the Deck Front–to–Rear Pitch
by Adjusting Front Height–of–Cut Posts
1. To change the front-to-rear pitch, the front
height–of–cut posts can be adjusted (Fig. 51).
2. To raise the front of the deck, loosen jam nut and
rotate the front pin clockwise (Fig. 51).
3. To lower the front of the deck, loosen jam nut and
rotate the front pin counter clockwise (Fig. 51).
