Why won't my Toro Lawn Mower engine start or keep running?
- D
  Daniel JacksonAug 13, 2025
  If your Toro Lawn Mower's engine won't start, starts with difficulty, or stalls, there are several potential causes. First, ensure the fuel tank is adequately filled with fuel. If the issue persists, inspect the air cleaner for dirt and either clean or replace the air cleaner element. Another possibility is a dirty fuel filter, which would require replacement. For issues related to dirt, water, or stale fuel in the fuel system, it's best to contact an Authorized Service Dealer.

What to do if my Toro Lawn Mower starter does not crank?
- A
  Ashley RiceAug 17, 2025
  If the starter on your Toro Lawn Mower isn't cranking, several issues could be the cause. First, ensure the blade control (PTO) is disengaged. Next, confirm that the parking brake is engaged and that you are seated on the seat. Check the battery; if it's dead, charge it. Also, inspect the electrical connections to ensure they are clean and tight. Replace the fuse if it's blown. If none of these steps work, the relay or switch may be defective, and you should contact an Authorized Service Dealer.

Why is my Toro Lawn Mower engine losing power?
- D
  Devon HuffAug 20, 2025
  If your Toro Lawn Mower engine is losing power, consider these possible causes and solutions. First, reduce your ground speed if the engine load is excessive. If that doesn't help, clean the air cleaner element if it's dirty. Also, make sure the oil level in the crankcase is sufficient by adding oil if it's low. Check for any obstructions blocking the cooling fins and air passages above the engine and remove them. Ensure the vent hole in the fuel cap isn't plugged by cleaning or replacing the cap. Replace the fuel filter if it's dirty. For issues related to dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.

  If your Toro Lawn Mower isn't driving, there are several possible reasons. Ensure the bypass valve is tightly closed. If not, tighten it. Check the drive or pump belt for wear, looseness, or breakage; replace the belt if necessary. If the drive or pump belt is off a pulley, replace the belt. Replace any broken or missing idler springs. Finally, check the hydraulic fluid level; add fluid to the reservoir if it's low, or allow it to cool down if it's too hot.

  If your Toro Lawn Mower is leaving an uneven cutting height, several factors could be responsible. Start by sharpening the blades if they are dull. If the cutting blades are bent, replace them with new ones. Ensure the mower is level from side to side and front to rear. Clean the underside of the mower deck if it's dirty. Adjust the tire pressure to the correct level. For issues related to a bent blade spindle, contact an Authorized Service Dealer.

  If your Toro Lawn Mower is experiencing abnormal vibration, there are several potential causes. Start by checking the cutting blades; if they are bent or unbalanced, install new ones. Ensure the blade mounting bolt is tightened securely. Also, check the engine mounting bolts and tighten them if they are loose.

  Stacy CamposSep 8, 2025
  If the blades on your Toro Lawn Mower aren't rotating, there are a few things to inspect. Check the drive belt for wear, looseness, or breakage, and verify the belt tension. If the drive belt is off the pulley, install the drive belt and check the adjusting shafts and belt guides for correct positioning. If the deck belt is worn, loose, or broken, install a new deck belt. If the deck belt is off the pulley, install the deck pulley and check the idler pulley, idler arm, and spring for correct position and function. Replace any broken or missing idler springs.
