Correcting Cutting Unit
Mismatch
If one deck blade cuts lower than the other, correct as
follows.
Note:
Tire air pressure is critical in these procedures.
Make sure all tires have correct pressure.
1. Stop the engine, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Adjust the tire pressure in all tires to specifications on
page 28.
3. Check that the blades and spindle shafts are not bent.
Refer to Checking for Bent Blades on page 31.
4. Set the height-of-cut to the 4 in. (102 mm) position.
Refer to Adjusting the Height-Of-Cut in the Operation
section.
5. Perform steps in the following sections Frame Set Up,
Checking Front–to–Rear Pitch and Checking
Side–to–Side Leveling.
Setting up the Frame
Checking Carrier Frame and Deck
Alignment
1. Stop the engine, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Place a long straight edge on top of the engine deck as
shown in figure 48.
3. At the carrier frame cross tube, measure location A
height (Fig. 48). This measurement must be
2–13/16 in. (71 mm), plus or minus a 1/4 in. (6 mm).
4. If the height at location A is not correct, adjustment is
needed.
5. Loosen the carrier frame mounting bolts on both sides
of the machine (Fig. 48).
6. Align the carrier frame and engine deck to match
2–13/16 in. (71 mm), plus or minus a 1/4 in. (6 mm) at
location A (Fig. 48).
7. Tighten the carrier frame mounting bolts on both sides
of the machine.

1. Stop the engine, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Adjust the tire pressure in all tires to specifications on
page 28.
3. Measure engine deck height at location A (Fig. 49).
4. Measure engine deck height at location B (Fig. 49).
