3. Place a long straight edge on top of the engine deck as
shown in figure 66.
4. At the carrier frame cross tube, measure location A
height (Fig. 66). This measurement must be
1–5/16 inch (33 mm), plus or minus a 1/4 inch (6 mm).
5. If the height at location A is not correct, adjustment is
needed.
6. Loosen the carrier frame mounting bolts on both sides
of the machine (Fig. 66).
7. Align the carrier frame and engine deck to match
1–5/16 inch (33 mm), plus or minus a 1/4 inch (6 mm)
at location A (Fig. 66).
8. Tighten the carrier frame mounting bolts on both sides
of the machine.

3. Adjust the tire pressure in all tires to specifications on
page 33.
4. Measure engine deck height at location A (Fig. 67).

Checking Carrier Frame Front–to–Rear
Pitch
The carrier frame must have a pitch of a 1/4 inch (6 mm)
over the length of 24 inches (61 cm) on the carrier frame
(Fig. 68).
1. Measure out 24 inches (61cm) on the carrier frame
(Fig. 68).
2. Measure carrier frame height at location A (Fig. 68).
3. Measure carrier frame height at location B (Fig. 68).
4. The height at location A must be a 1/4–3/8 inch
(6 mm –10 mm) lower than location B (Fig. 68).
5. If the carrier frame is not correct, move caster spacers
to make it a 1/4–3/8 inch (6 –10 mm) pitch (Fig. 68).
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.
