What to do if my Toro TimeCutter Z5000 74391 engine will not start?

  Robert PopeJul 26, 2025
  If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, make sure the fuel tank isn't empty by filling it. Ensure the choke is on by moving the choke lever to the 'On' position. A dirty air cleaner can cause issues, so clean or replace it. Check the spark plug wire(s) and install them securely on the spark plug. Replace any pitted, fouled, or incorrectly gapped spark plugs with new ones. Also, replace the fuel filter if it's dirty. If there's incorrect fuel in the fuel tank, drain it and replace it with the proper type. Finally, ensure the oil level in the crankcase is sufficient by adding oil if needed. If the problem persists, it may be due to dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

  If your Toro Lawn Mower blades do not rotate, install a new drive belt if the current one is worn, loose, or broken. If the drive belt is off the pulley, reinstall it and check the adjusting shafts and belt guides for the correct position. Also, install a new mower belt if the current one is worn, loose, or broken.

  For an uneven cutting height with your Toro Lawn Mower, sharpen the blade(s) if they are not sharp. Install a new cutting blade(s) if any are bent. Level the mower from side-to-side and front-to-rear. Adjust the anti-scalp wheel height if it's not set correctly. Clean the underside of the mower if it's dirty. Adjust the tire pressure to the correct level. If a blade spindle is bent, contact an Authorized Service Dealer.

Why is my Toro TimeCutter Z5000 74391 engine overheating?

  If your Toro Lawn Mower engine overheats, several factors could be the cause. It might be due to an excessive engine load, in which case you should reduce the ground speed. Alternatively, the oil level in the crankcase may be low, requiring you to add oil. Another potential cause is blocked cooling fins and air passages under the engine blower housing; remove any obstructions. A dirty air cleaner could also be the culprit, so clean or replace the air cleaner element. If the issue persists, it could be due to dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

  If the starter on your Toro Lawn Mower isn't cranking, ensure the blade control switch is disengaged. Move the motion control levers to the park position. Make sure you are seated. If the battery is dead, charge it. Check for corroded or loose electrical connections and ensure good contact. Replace any blown fuses. If these steps don't resolve the issue, a relay or switch may be damaged, and you should contact an Authorized Service Dealer.

  If your Toro Lawn Mower engine loses power, try the following: reduce ground speed if the engine load is excessive. Clean the air cleaner element if it's dirty. Add oil to the crankcase if the oil level is low. Remove any obstructions from the cooling fins and air passages. Install new, correctly gapped spark plug(s) if the current ones are pitted, fouled, or have an incorrect gap. Open the vent in the fuel cap if it's closed. Replace the fuel filter if it's dirty. If there is incorrect fuel in the fuel tank, drain the tank and replace the fuel with the proper type. If the issue persists, it could be due to dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

  If you notice abnormal vibration in your Toro Lawn Mower, check and tighten the engine mounting bolts if they are loose. Also, tighten the engine pulley, idler pulley, or blade pulley if any of them are loose. If the engine pulley is damaged or a blade spindle is bent, contact an Authorized Service Dealer.
