  If your Toro Lawn Mower doesn't drive, first check that the bypass valves are closed tight. If not, tighten them. Also, inspect the pump belt for wear, looseness, or breakage and change the belt if needed. Ensure the pump belt is correctly positioned on the pulley. Replace the spring if the idler spring is broken or missing. Finally, verify the hydraulic fluid level; add hydraulic fluid to the reservoirs if it is low, or let it cool down if it is too hot.

Why Toro 74923 blades do not rotate?
- B
  Bridget GutierrezAug 27, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken mower deck belt; in this case, install a new deck belt. Another possibility is that the mower deck belt is off the pulley; reinstall it and check the idler pulley, idler arm, and spring for correct position and function. Also, check the pump drive belt for wear, looseness, or breakage, and adjust the belt tension or install a new belt. Finally, inspect the idler spring and replace it if it's broken or missing.
