Checking Carrier Frame Front–to–Rear
Pitch
The carrier frame must have a pitch of a 1/4 in. (6 mm)
over the length of 24 inches (6.1 cm) on the carrier frame.
1. Measure out 24 inches on the carrier frame (Fig. 50).
2. Measure carrier frame height at location A (Fig. 50).
3. Measure carrier frame height at location B (Fig. 50).
4. The height at location A must be a 1/4–3/8 in.
(6 mm – 10 mm) lower than location B (Fig. 50).
5. If the carrier frame is not correct, move caster spacers
to make it a 1/4–3/8 in. (6 mm – 10 mm) pitch
(Fig. 50). Move spacers from top or bottom to make
the correct pitch.
6. The tire pressure may also be adjusted slightly to make
a 1/4–3/8 in. (6 mm – 10 mm) pitch.

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. 51).
4. Measure carrier frame height at location B (Fig. 51).
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. 52). Measure at
C and D locations (Fig. 52) from a level surface to the
cutting edge of the blade tips (Fig. 53).
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.
