Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 59). 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 60). 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 60). Repeat this
procedure until the blade is balanced.

Installing the Blades
1. Install the bolt, curved washer, and blade. Select the
proper number of spacer(s) for the height-of- cut,
and slide the bolt into the spindle (Figure 58).
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 (Figure 58).
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 brakes.
3. If necessary, adjust the spring mounting bolts so that
the blade brake pad rubs against both sides of the
pulley groove (Figure 61).
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 61).
5. Engage the blades. Ensure the blade brake pad no
longer contacts the pulley groove.
