5. Measure engine deck height at location B
(Figure 52).
6. If the height at location A and B are not the
same, change tire pressure slightly to make
them the same.
Checking the Carrier Frame
Front-to-Rear Pitch
The carrier frame must have a pitch between 1/8
inch (3 mm) to 3/8 inch (9 mm) over the length of
24 inches (61 cm) on the carrier frame (Figure 53).
1. Measure out 24 inches (61 cm) on the carrier
frame (Figure 53).

3. Measure carrier frame height at location B
(Figure 53).
4. The height at location A must be a 1/4-3/8
inch (6 mm -10 mm) lower than location B
(Figure 53).
5. If the carrier frame is not correct, move caster
spacers to make it a 1/4-3/8 inch (6 -10 mm)
pitch (Figure 53). 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 the Carrier Frame
Side-to-Side Height
The carrier frame needs to be parallel side-to-side
from the ground.
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 the
rear tires to specifications; refer to
Drive System Maintenance, page 30 .
4. Measure carrier frame height at location A
(Figure 54).
5. Measure carrier frame height at location B
(Figure 54).
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.
