Checking the Engine Deck Height
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 engine deck height at location A (Figure 62).

2. Top of engine deck
5. Measure engine deck height at location B (Figure 62).
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 63).
1. Measure out 24 inches (61 cm) on the carrier frame
(Figure 63).

4. Same height at locations
A and B

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 63).
3. Measure carrier frame height at location B (Figure 63).
4. The height at location A must be a 1/4-3/8 inch (6 mm
-10 mm) lower than location B (Figure 63).
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 63).
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 64).
5. Measure carrier frame height at location B (Figure 64).
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.
