Why Toro 74492 starter does not crank?
- S
  Sabrina HubbardAug 18, 2025
  If the starter on your Toro Lawn Mower isn't cranking, here are a few things to check: First, make sure the blade-control switch is disengaged. Next, ensure the motion-control levers are in the NEUTRAL-LOCK position by moving them outward. If those aren't the issue, the battery might be dead, so try charging it. Also, check the electrical connections for any corrosion or looseness, ensuring they have good contact. Replace the fuse if it's blown. For a damaged relay or switch, it's best to contact an Authorized Service Dealer.

  Katie BenjaminAug 21, 2025
  If your Toro Lawn Mower engine is losing power, consider these possible causes: the engine load may be too high, so reduce your ground speed. Check the air cleaner and clean the element if it's dirty. Ensure the oil level in the crankcase is adequate; add oil if needed. Inspect the cooling fins and air passages above the engine for obstructions and remove them. Also, verify the vent hole in the fuel cap isn't plugged; clean or replace the cap if it is. Replace the fuel filter if it is dirty. For issues related to dirt, water, or stale fuel in the fuel system, it's best to contact an Authorized Service Dealer.

Check the pump belt for wear, looseness, or breakage; change the belt if needed. Verify the pump belt is properly on the pulley; change the belt if it is off. Inspect the idler spring for breakage or if it's missing; replace the spring if necessary.

How to fix uneven cutting height on my Toro Lawn Mower?
- M
  mckayjerryAug 28, 2025
  If the cutting height on your Toro Lawn Mower is uneven, several factors could be responsible. Make sure the blade(s) is sharp; sharpen them if needed. If a cutting blade(s) is bent, install a new one. Ensure the mower is level from side-to-side and front-to-rear. If applicable, check that the anti-scalp roller is set correctly and adjust the anti-scalp wheel height. Clean the underside of the mower deck if it's dirty. Verify that the tire pressure is correct and adjust it as necessary. For a bent blade spindle, it's best to contact an Authorized Service Dealer.

Tighten them. * Check if the engine pulley, idler pulley, or blade pulley is loose and tighten the appropriate pulley.

Why does my Toro 74492 pull to one side?
- S
  Sarah MendozaSep 9, 2025
  If your Toro Lawn Mower pulls to the left or right even with the levers fully forward, it could be due to tracking issues or incorrect tire pressure. Try adjusting the tracking. Also, adjust the tire pressure in the drive tires to ensure it is correct.
