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 26) .
4. Measure engine deck height at location A (Figure 55).
5. Measure engine deck height at location B (Figure 55).
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 3 mm (1/8 inch)
to 9 mm (3/8 inch) over the length of 61 cm (24 inches) on
the carrier frame (Figure 56).
1. Measure out 61 cm (24 inches) on the carrier frame
(Figure 56).

2. 3 to 10 mm (1/8 inch to 3/8
inch) pitch over 61 cm (24
inch) length
3. 61 cm (24 inches)
2. Measure carrier frame height at location A (Figure 56).
3. Measure carrier frame height at location B (Figure 56).
4. The height at location A must be an 3 mm to 10 mm
(1/8 to 3/8 inch) lower than location B (Figure 56).
5. If the carrier frame is not correct, move caster spacers
to make it an 3 mm to 10 mm (1/8 to 3/8 inch) pitch
(Figure 56). Move spacers from top or bottom to make
the correct pitch.
6. The tire pressure may also be adjusted slightly to make
an 3 mm to 10 mm (1/8 to 3/8 inch) pitch.
