Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 41). 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 42). 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

Installing the Blades
1. Place the blade onto the bolt and over the curved
washer. Select the proper number of spacer(s) for
the height-of- cut, and slide the bolt into the spindle
(Figure 40).
Important: The curved part of the blade must
point upward toward the inside of the mower to
ensure proper cutting.
2. Install the remaining spacer(s) and secure them with
a thin washer and a nut (Fig. Figure 40).
3. Torque the blade bolt to 75-80 ft-lb (101-108 N•m).

Adjusting the Blade Brake

1. Disengage the PTO, turn the ignition key to off, and
remove the key.
2. Wait for all moving parts to stop before leaving the
operating position and then set the parking brake.
3. If necessary, adjust the spring mounting bolts so that
the blade brake pad rubs against both sides of the
pulley groove (Figure 43).
4. Adjust the nut at the end of the blade brake rod until
there is 1/8-3/16 inch (3 mm -5 mm) between the
nut and spacer (Figure 43).
5. Engage the blades. Ensure the blade brake pad no
longer contacts the pulley groove.
