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 54).
1. Measure out 24 inches (61 cm) on the carrier frame
(Figure 54).

2. 1/4-3/8 inch (6-10 mm)
pitch over 24 inch (61 cm)
length
3. 24 inches (61 cm)
2. Measure carrier frame height at location A (Figure 54).
3. Measure carrier frame height at location B (Figure 54).
4. The height at location A must be a 1/4-3/8 inch (6 mm
-10 mm) lower than location B (Figure 54).
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 54).
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 28) .
4. Measure carrier frame height at location A (Figure 55).
5. Measure carrier frame height at location B (Figure 55).
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.
