Adjusting The Blade Brake - Toro 30672 Operator's Manual

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 58). 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 59). 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 59). Repeat this procedure
until the blade is balanced.

Installing the Blades
1. Install the curved washer and then the blade onto
the bolt. Select the proper number of spacer(s) for
the height-of- cut, and slide the bolt into the spindle
(Figure 57).
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 57).
3. Torque the blade bolt to 101-108 N-m (75-80 ft-lb).

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 60).
4. Adjust the nut at the end of the blade brake rod until
there is 3 mm -5 mm (1/8-3/16 inch) between the nut
and spacer (Figure 60).
5. Engage the blades. Ensure the blade brake pad no
longer contacts the pulley groove.
