1. Sharpen at original angle
2. Check the balance of the blade by putting it on a blade
balancer (Fig. 57). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
blade is not balanced, file some metal off the end of
the sail area only (Fig. 55). Repeat this procedure until
the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Fig. 55).
Important
The sail part of the blade must be pointing
upward, toward the inside of the mower to ensure proper
(Fig. 55).

Correcting Cutting Unit
Mismatch
If one deck blade cuts lower than the other, correct as
follows.
Tire air pressure is critical in these procedures.
Note:
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 30.
3. Check that the blades and spindle shafts are not bent.
Refer to Checking for Bent Blades on page 42.
4. Set the height-of-cut to the 4 in. (102 mm) position.
Refer to Adjusting the Height-Of-Cut in the Operation
section.

Side–to–Side Leveling.
Frame Set Up
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 58.
3. At the carrier frame cross tube, measure location "A"
height (Fig. 58). This measurement must be 2–13/16
in. (71.4 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. 58).
6. Align the carrier frame and engine deck to match
2–13/16 in. (71.4 mm), plus or minus a 1/4 in. (6 mm)
at location "A" (Fig. 58).
7. Tighten the carrier frame mounting bolts on both sides
of the machine.
