How to Replace a Toro Snow-Blower Rotor Blade

Toro snow blowers use rotating blades to churn up snow from the ground and into the chute. Over time, the blades can become dull and less effective from repeatedly striking the ground. If your Toro snow-blower rotor blades show signs of wear, it’s time to replace them. If you own an older single-stage Toro snow blower made before 1992, you can replace the snow-blower blades yourself.

Ratchet set with a 7/16-inch socket
Ratchet extension (optional)
Oil lubricant (optional)

Instructions

- 1
  Stop your Toro snow blower and disconnect the spark plug. Lay your snow blower down -- so the blades face straight forward.
- 2
  Use your ratchet set with the 7/16-inch socket to remove the bolts on each blade. You may need to spray the lubricant oil or use an extension on your ratchet set for additional leverage. Take off the washers and lock nuts.
- 3
  Slide the blade out from between the steel plates. Remove the spacer bushings from out of the blade holes and keep them.
- 4
  Put the spacer bushings inside the new blade’s holes.
- 5
  Place the new blade between the steel plates with the thicker side down, to keep the snow blower balanced.
- 6
  Reinstall the bolts, washers and lock nuts where applicable. Start with the center bolts and only tighten until barely snug. Once all the bolts are installed, re-tighten the bolts.
