What to do if the blades do not rotate on my Toro 74266 Lawn Mower?
- D
  Dillon WillisSep 9, 2025
  If the blades on your Toro Lawn Mower do not rotate, it could be due to a worn, loose, or broken drive belt, so check the belt tension. It could also be that the drive belt is off the pulley, so install the drive belt and check the adjusting shafts and belt guides for correct position. Another possibility is a worn, loose, or broken deck belt, so install a new deck belt. It may also be that the deck belt is off the pulley, so install the deck pulley and check the idler pulley, idler arm, and spring for correct position and function. Finally, a broken or missing idler spring could be the cause, so replace the spring.

  If your Toro Lawn Mower engine won't start, struggles to start, or keeps cutting out, there are several potential causes: * The fuel tank may be empty, in which case you should fill it with fuel. * The air cleaner might be dirty; try cleaning or replacing the air cleaner element. * There could be dirt in the fuel filter, so replace the fuel filter. * If the issue persists, there may be dirt, water, or stale fuel in the fuel system, so contact an Authorized Service Dealer.

  If the blades on your Toro Lawn Mower do not rotate, check if the mower deck belt is worn, loose, or broken, and install a new deck belt if needed. If the mower deck belt is off the pulley, reinstall it and inspect the idler pulley, idler arm, and spring for correct position and function. Also, inspect the pump drive belt for wear, looseness, or breakage; check the belt tension or install a new belt. Finally, replace the idler spring if it's broken or missing.

  If your Toro Lawn Mower engine is losing power, there are several possible causes. First, reduce the ground speed if the engine load is excessive. Check the air cleaner and clean the element if it's dirty. Ensure the oil level in the crankcase is adequate, adding oil if it's low. Remove any obstructions from the cooling fins and air passages. Clean or replace the fuel cap if the vent hole is plugged. Replace the fuel filter if it's dirty.
