Tire air pressure is critical in these procedures.
Note:
Make sure all tires have correct pressure.
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 all tires to specifications on
page 36.
4. Check that the blades and spindle shafts are not bent.
Refer to Checking for Bent Blades on page 47.

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. Place a long straight edge on top of the engine deck as
shown in figure 69.
4. At the carrier frame cross tube, measure location A
height (Fig. 69). 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. 69).
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. 69).
