5. Measure engine deck height at location
B
(Figure 73).
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 74).
1. Measure out 24 inches (61 cm) on the carrier
frame (Figure 74).

2. Measure carrier frame height at location
A
(Figure 74).
3. Measure carrier frame height at location
B
(Figure 74).
4. The height at location
A
must be an 1/8-3/8
inch (3 mm -10 mm) lower than location
B
(Figure 74).
5. If the carrier frame is not correct, move caster
spacers to make it an 1/8-3/8 inch (3 -10 mm)
pitch (Figure 74). Move spacers from top or
bottom to make the correct pitch.
6. The tire pressure may also be adjusted slightly
to make an 1/8-3/8 inch (3 -10 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 36 .
4. Measure carrier frame height at location
A
(Figure 75).
5. Measure carrier frame height at location
B
(Figure 75).
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.
