Servicing The Air Cleaner - Toro 30150 Operator's Manual

Warning
A blade that is bent or damaged could break apart
and could seriously injure or kill you or
bystanders.
Always replace bent or damaged blade with a
new blade.
Never file or create sharp notches in the edges
or surfaces of the blade.
Removing the Blades
Replace the blades if you hit a solid object or if the blades
are out of balance or bent. To ensure optimum performance
and continued safety conformance of the machine, use
genuine Toro replacement blades. Replacement blades
made by other manufacturers may result in
non-conformance with safety standards.
1. Hold the blade bolt with a wrench.
2. Remove the nut, blade bolt, cone washer, blade,

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 30). 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 (Fig. 31). 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. 30). Repeat this step until the blade
is balanced.

Installing the Blades
1. Place the blade onto the bolt and over the cone washer.

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. 29).
3. Torque the blade bolt to 75–80 ft-lb (101–108 N m).
