Why does my Toro 74665 engine lose power?
- S
  ssimpsonSep 2, 2025
  If your Toro Lawn Mower engine is losing power, consider these potential causes: The engine load might be too high, so reduce the ground speed. A dirty air cleaner can restrict airflow, so clean the air-cleaner element. Check the oil level in the crankcase and add oil if necessary. Clear any obstructions from the cooling fins and air passages under the engine blower housing. Replace the spark plug(s) if it is pitted, fouled, or the gap is incorrect. If there is incorrect fuel in the fuel tank, drain the tank and replace the fuel with the proper type. For issues like a blocked fuel-tank vent, dirt, water, or stale fuel in the fuel system, it's best to contact an Authorized Service Dealer. Also, if there is dirt in the fuel filter, replace the fuel filter.

What to do if Toro 74665 Lawn Mower blades do not rotate?
- B
  Brett StewartSep 1, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken drive belt (install a new one). Also, ensure the drive belt is properly installed on the pulley and check the adjusting shafts and belt guides for the correct position. If the Power Take-Off (PTO) switch or PTO clutch is faulty, or if the mower belt is worn, loose, or broken, contact an Authorized Service Dealer, or install a new mower belt, respectively.

  If your Toro Lawn Mower isn't driving, begin by checking if the bypass valves are open; if so, close the tow valves. For issues related to worn, loose, or broken traction belts, traction belts off of the pulleys, or a failed transmission, contact an Authorized Service Dealer.

Why won't my Toro Lawn Mower engine start?
- J
  jenniferstewartAug 30, 2025
  If your Toro Lawn Mower engine isn't starting, starts with difficulty, or won't stay running, possible causes include an empty fuel tank (fill it), the choke not being on (turn it on), a dirty air cleaner (clean or replace it), loose or disconnected spark-plug wire(s) (install them), a faulty spark plug (replace it with a new, correctly gapped one), or dirt in the fuel filter (replace the filter). Also, check for incorrect fuel in the tank (drain and replace it with the proper type) and low oil level in the crankcase (add oil). For dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.

  If your Toro Lawn Mower's engine doesn't start, starts with difficulty, or won't stay 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 is securely connected to the spark plug. Inspect the spark plug itself; if it's damaged or improperly gapped, replace it with a new one. Also, check for a dirty fuel filter and replace if needed. If there is incorrect fuel in the fuel tank, drain the tank and replace the fuel with the proper type. Finally, verify that the oil level in the crankcase is sufficient and add oil if low.

How to adjust Toro 74665 cutting height uneven?
- A
  Alex BarryAug 28, 2025
  Uneven cutting height on your Toro Lawn Mower can be caused by dull blades (sharpen them) or bent cutting blades (replace them). Ensure the mower is level from side-to-side and front-to-rear. Check the anti-scalp wheel settings and adjust their height as needed. Clean any dirt from the underside of the mower. Also, verify and adjust the tire pressure. If a blade spindle is bent, contact an Authorized Service Dealer.

How to fix a Toro Lawn Mower when the starter does not crank?

  zjacksonAug 27, 2025
  If the starter on your Toro Lawn Mower isn't cranking, start by ensuring the blade-control switch is disengaged. Also, make sure the motion-control levers are in the PARK position. Check the battery and charge it if it's dead. Inspect the electrical connections for corrosion or looseness, ensuring they have good contact. Replace the fuse if it's blown. If these steps don't solve the problem, a relay or switch may be damaged, requiring you to contact an Authorized Service Dealer.

  Several factors can prevent your Toro Lawn Mower's engine from starting. It could be as simple as an empty fuel tank; in this case, fill the fuel tank. Other potential causes include a missing choke (move the choke lever to On), a dirty air filter (clean or replace it), a loose or disconnected spark-plug wire (secure the wire to the spark plug), a faulty spark plug (replace with a new, correctly gapped one), a dirty fuel filter (replace it), incorrect fuel type (drain and replace with the proper type), or low oil level (add oil to the crankcase). If the problem persists, there might be dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.
