Why won't my Toro Lawn Mower engine start?
- K
  kcummingsAug 6, 2025
  If your Toro Lawn Mower's engine won't start, starts with difficulty, or stops running, the possible causes include an empty fuel tank (fill it with gasoline), a closed fuel valve (open it), choke not being on (move the choke lever to the 'on' position), a dirty air cleaner (clean or replace the air cleaner element), loose or disconnected spark plug wires (install the wires on the spark plug), spark plugs that are pitted, fouled, or have an incorrect gap (install new, correctly gapped spark plugs), or a dirty fuel filter (replace the fuel filter). If these steps don't resolve the issue, it could be due to dirt, water, or stale fuel in the fuel system, which requires contacting an Authorized Service Dealer.

What to do if Toro Z Master Z147 Lawn Mower blades do not rotate?
- W
  woodshelenAug 10, 2025
  If your Toro Lawn Mower blades do not rotate, possible causes include the mower belt being off the pulley (install the mower belt and check the adjusting plate, idler arm and spring, and belt guides for correct position) or the mower belt being worn, loose, or broken (install a new mower belt). If these aren't the causes, the electric clutch may not be engaging or is worn, in which case you should contact an Authorized Service Dealer.

Why is my Toro Z Master Z147 Lawn Mower engine losing power?
- J
  Jeffrey StephensAug 15, 2025
  If your Toro Lawn Mower engine loses power, it may be due to several reasons. The engine load might be excessive, so try reducing your ground speed. A dirty air cleaner can also cause power loss; clean the air cleaner element. Check the oil level in the crankcase and add oil if it's low. Ensure that the cooling fins and air passages under the engine blower housing are free from obstructions. Replace pitted, fouled, or incorrectly gapped spark plugs with new ones that are correctly gapped. Also, replace a dirty fuel filter. If the problem persists, there might be dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

How to fix uneven cutting height on my Toro Lawn Mower?
- W
  William HickmanAug 20, 2025
  If your Toro Lawn Mower is cutting unevenly, try sharpening the blades and, if bent, install new cutting blades. Ensure the mower is level from side-to-side and front-to-rear. Adjust the gage wheel height if it's not set correctly. Clean the underside of the mower if it's dirty, and adjust the tire pressure if it's incorrect. If the blade spindle is bent, contact an Authorized Service Dealer.

What to do if my Toro Z Master Z147 Lawn Mower starter does not crank?
- C
  Christopher JacksonAug 26, 2025
  If the starter on your Toro Lawn Mower doesn't crank, make sure that the blade control (PTO) is disengaged, the parking brake is set, and you are seated on the seat. Check if the battery is dead and charge it if necessary. Also, verify that the electrical connections are making good contact and replace the fuse if it's blown. If the issue persists, the relay or switch might be defective, and you should contact an Authorized Service Dealer.

- L
  lisa97Aug 30, 2025
  If your Toro Lawn Mower is producing an abnormal vibration, check and tighten the engine mounting bolts. Also, tighten any loose engine, idler, or blade pulleys. If any engine pulley is damaged, contact an Authorized Service Dealer. Replace any bent or unbalanced cutting blades and tighten the blade mounting bolt. If the blade spindle is bent, contact an Authorized Service Dealer.
