Checking Carrier Frame Front–to–Rear
Pitch
The carrier frame must have a pitch of a 1/4 inch (6 mm)
over the length of 24 inches (61 cm) on the carrier frame
(Fig. 56).
1. Measure out 24 inches (61cm) on the carrier frame
(Fig. 56).
2. Measure carrier frame height at location A (Fig. 56).
3. Measure carrier frame height at location B (Fig. 56).
4. The height at location A must be a 1/4–3/8 inch
(6 mm –10 mm) lower than location B (Fig. 56).
5. If the carrier frame is not correct, move caster spacers
to make it a 1/4–3/8 inch (6 –10 mm) pitch (Fig. 56).
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 inch (6 mm) pitch.

Checking Carrier Frame Side–to–Side
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Adjust the tire pressure in all tires to specifications on
page 32.
4. Measure carrier frame height at location A (Fig. 57).
5. Measure carrier frame height at location B (Fig. 57).
6. 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. 58). Measure at C
and D locations (Fig. 58) from a level surface to the
cutting edge of the blade tips (Fig. 59).
3. The mower blade should be 1/4 inch (6 mm) lower in
front at C than in the rear at D. Rotate blades and
repeat for other blades. If it is not correct, proceed to
Changing the Deck Front–to–Rear Pitch.
