Why Toro Lawn Mower blades do not rotate?
- K
  Kaitlyn KellyAug 31, 2025
  If your Toro Lawn Mower blades do not rotate, install a new deck belt if the current mower deck belt is worn, loose, or broken. If the mower deck belt is off the pulley, install it and check the idler pulley, idler arm, and spring for correct position and function. Check the belt tension or install a new belt if the pump drive belt is worn, loose, or broken. Replace the spring if the idler spring is broken or missing.

  If your Toro Lawn Mower's engine is overheating, reduce the ground speed if the engine load is excessive. Ensure the oil level in the crankcase is adequate by adding oil if it's low. Also, check for any obstructions blocking the cooling fins and air passages above the engine, and remove them.
