Why won't my Toro 74272CP engine start?
- J
  John HamiltonAug 13, 2025
  Your Toro Riding mower engine might not start due to several reasons. The fuel tank could be empty, so fill it with fuel. The air cleaner might be dirty, requiring you to clean or replace the air cleaner element. There might be dirt in the fuel filter, in which case you should replace it. If the issue persists, there might be dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

What to do if my Toro 74272CP starter does not crank?
- J
  Jeffrey LaneAug 17, 2025
  If the starter on your Toro Riding mower isn't cranking, there could be several reasons. Ensure the blade control (PTO) is disengaged, the parking brake is set, and you are seated. Also, check if the battery is dead and needs charging, or if the electrical connections are corroded or loose, requiring you to check them for good contact. A blown fuse could also be the problem, so replace it if necessary. If none of these solutions work, the relay or switch may be defective, in which case you should contact an Authorized Service Dealer.

How to troubleshoot a Toro 74272CP Riding mower engine that loses power?
- C
  christopher87Aug 20, 2025
  If your Toro Riding mower engine loses power, it could be due to several factors. The engine load might be excessive, so reduce the ground speed. A dirty air cleaner can cause this issue, so clean the air cleaner element. Check if the oil level in the crankcase is low and add oil if needed. Also, ensure the cooling fins and air passages above the engine are not plugged, and remove any obstructions. A plugged vent hole in the fuel cap could also be the culprit, so clean or replace the fuel cap. Finally, check for dirt in the fuel filter and replace it if necessary. If problems persist, there might be dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

What causes the blades on my Toro 74272CP not to rotate?
- B
  Brooke WalkerAug 25, 2025
  If the blades on your Toro Riding mower aren't rotating, several issues could be the cause. Check if the drive belt is worn, loose, or broken and verify the belt tension. Ensure the drive belt is properly positioned on the pulley and check the adjusting shafts and belt guides for correct positioning. Inspect the deck belt for wear, looseness, or breakage, and install a new deck belt if needed. Verify the deck belt is on the pulley and check the idler pulley, idler arm, and spring for correct position and function. Finally, check for a broken or missing idler spring and replace it if necessary.

Why does my Toro Riding mower have an uneven cutting height?
- W
  William HubbardAug 28, 2025
  Uneven cutting height on your Toro Riding mower can be attributed to several factors. Start by sharpening the blade(s). If the cutting blade(s) are bent, replace them. Ensure the mower is level from side-to-side and front-to-rear. Clean the underside of the mower deck, and adjust the tire pressure to the correct levels. For a bent blade spindle, contact an Authorized Service Dealer.

  Susan WoodSep 1, 2025
  If your Toro Riding mower isn't driving, first check that the bypass valve is closed tight and tighten it if necessary. Also, inspect the drive or pump belt for wear, looseness, or breakage, and change the belt if needed. Ensure the drive or pump belt is properly on the pulley; if it's off, change the belt. Check for a broken or missing idler spring and replace it if necessary. Finally, verify that the hydraulic fluid level is adequate and not too hot; add hydraulic fluid to the reservoir or let it cool down.
