What to do if Toro TITAN ZX 5400 blades do not rotate?
- J
  Jacob ReynoldsSep 5, 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; install a new deck belt. Another possibility is that the mower deck belt is off the pulley; install the mower deck pulley and check the idler pulley, idler arm, and spring for correct position and function. Also, check if the pump drive belt is worn, loose, or broken; check the belt tension or install new belt. Finally, inspect the idler spring for breaks or missing parts; replace the spring if necessary.
