Why my Toro 77506 Lawn Mower engine does not start?
- J
  Jamie GarciaAug 12, 2025
  If your Toro Lawn Mower engine does not start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank isn't empty by filling it. If your model has a choke, make sure it's turned on. A dirty air cleaner can also cause issues, so clean or replace it. Check that the spark-plug wire(s) is securely connected and that the spark plug(s) isn't damaged or improperly gapped; replace if necessary. Other potential causes include a dirty fuel filter (replace it), dirt, water, or stale fuel in the fuel system (in this case you should contact an Authorized Service Dealer), incorrect fuel in the tank (drain and replace with the proper type), or low oil level in the crankcase (add oil).

Why is my Toro Lawn Mower engine overheating?
- W
  wattsheatherAug 16, 2025
  If your Toro Lawn Mower engine overheats, there are several potential causes. First, the engine load might be excessive, so try reducing the ground speed. Check the oil level in the crankcase and add oil if it's low. Make sure the cooling fins and air passages under the engine-blower housing are clear of obstructions. Also, a dirty air cleaner can contribute to overheating, so clean or replace the air-cleaner element. If dirt, water, or stale fuel is in the fuel system, contact an Authorized Service Dealer.

How to fix uneven cutting height on my Toro Lawn Mower?

  Ryan VazquezAug 19, 2025
  If your Toro Lawn Mower cutting height is uneven, several factors could be the cause. Start by sharpening the blade(s). Replace any bent cutting blade(s). Ensure the mower is level from side-to-side and front-to-rear. If applicable, adjust the anti-scalp wheel height. Clean the underside of the mower deck. Adjust the tire pressure. If a blade spindle is bent, contact an Authorized Service Dealer.

What to do if the blades do not rotate on my Toro Lawn Mower?
- B
  Brittany JacobsAug 25, 2025
  If the blades on your Toro Lawn Mower do not rotate, several issues could be the cause. Check if the drive belt is worn, loose, or broken, and install a new one if needed. If the drive belt is off of the pulley, reinstall it and check the adjusting shafts and belt guides for the correct position. If the power-takeoff (PTO) switch or PTO clutch is faulty, or if the mower belt is worn, loose, or broken, contact an Authorized Service Dealer to resolve these issues.

What to do if my Toro 77506 Lawn Mower engine loses power?
- U
  ujonesAug 28, 2025
  If your Toro Lawn Mower engine loses power, consider these possible causes: the engine load may be excessive, so reduce the ground speed. A dirty air cleaner can also cause power loss, so clean it. Check the oil level and add oil to the crankcase if it's low. Clear any obstructions from the cooling fins and air passages under the engine blower housing. Replace any pitted, fouled, or incorrectly gapped spark plug(s). For issues like a blocked fuel-tank vent, dirt in the fuel filter, or incorrect fuel, it is best to contact an Authorized Service Dealer.

What to do if the starter does not crank on my Toro Lawn Mower?
- C
  colinjacobsAug 31, 2025
  If your Toro Lawn Mower starter does not crank, there are several things to check. Ensure the blade-control switch is disengaged and the motion-control levers are in the PARK position. A dead battery could be the culprit, so charge it. Inspect the electrical connections for corrosion or looseness, ensuring they have good contact. Also, check if a fuse is blown and replace it if necessary. If a relay or switch is damaged, contact an Authorized Service Dealer.

Why does my Toro Lawn Mower vibrate abnormally?
- R
  Robert CarrSep 4, 2025
  If your Toro Lawn Mower vibrates abnormally, several issues could be responsible. Start by checking the cutting blade(s); if they are bent or unbalanced, install new ones. Ensure the blade mounting bolt and the engine mounting bolts are tightened. Also, check the engine pulley, idler pulley, or blade pulley and tighten them if loose. For a damaged engine pulley, bent blade spindle, or loose/worn motor mount, contact an Authorized Service Dealer.

  If your Toro Lawn Mower does not drive, the bypass valves may be open; close the tow valves. For issues such as traction belts that are worn, loose, or broken; traction belts that are off the pulleys; or a failed transmission, contact an Authorized Service Dealer.
