Checking the Carrier Frame
Front-to-Rear Pitch
The carrier frame must have a pitch between 3 mm (1/8 inch)
to 9 mm (3/8 inch) over the length of 61 cm (24 inches) on
the carrier frame (Figure 54).
1. Measure out 61 cm (24 inches) on the carrier frame
(Figure 54).

2. 6-10 mm (1/4-3/8 inch)
pitch over 61 cm (24 inch)
length
3. 61 cm (24 inches)
2. Measure the carrier-frame height at location A
54).
3. Measure the carrier-frame height at location B
54).
4. The height at location A must be a 6-10 mm (1/4-3/8
inch) lower than location B
5. If the carrier frame is not correct, move caster spacers
to make it a 6-10 mm (1/4-3/8 inch) pitch
Note: Move the spacers from the top or the bottom
to make the correct pitch.
6. The tire pressure may also be adjusted slightly to make
a 6 mm (1/4 inch) pitch.
Checking the Carrier Frame
Side-to-Side Height
Make sure the carrier frame is 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

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.
