Sharpening the Blades
1. Use a file to sharpen the cutting edge at both
ends of the blade (Figure 56). Maintain the
original angle. The blade retains its balance if
the same amount of material is removed from
both cutting edges.

2. Check the balance of the blade by putting it on
a blade balancer (Figure 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
(Figure 55). Repeat this procedure until the
blade is balanced.

Important: The sail part of the blade
must be pointing upward, toward the
inside of the mower to ensure proper
cutting (Figure 55).
2. Install the blade stiffener, flat washer and blade
bolt (Figure 55).
3. Torque the blade bolt to 85-110 ft-lb (115-140
N•m).
Correcting the Mower
Quality of Cut
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. 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. Disconnect the spark plug
wire(s) from the spark plug(s).
3. Adjust the tire pressure in all tires to
specifications on page .
4. Check that the blades and spindle shafts are
not bent. Refer to Checking for Bent Blades.
5. Set the height-of-cut to the 4 inch (101.6 mm)
position. Refer to Adjusting the Height-Of-Cut
in Operation, page 20.
6. Perform the steps in the following sections
Frame Set Up, Checking Front-to-Rear Pitch,
and Checking Side-to-Side Leveling.
