Why is my Toro Lawn Mower cutting height uneven?
- R
  Ryan TurnerAug 22, 2025
  If the cutting height of your Toro Lawn Mower is uneven, several factors could be the cause. Start by sharpening the blade(s). If a cutting blade(s) is bent, install a new one. Ensure the mower is level 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 if it's incorrect. If a blade spindle is bent, contact an Authorized Service Dealer.

  If your Toro Lawn Mower engine overheats, there are several potential causes. First, the engine load might be excessive, so try reducing your ground speed. Also, 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 free from obstructions. A dirty air cleaner can also contribute to overheating, so clean or replace it. Finally, dirt, water, or stale fuel in the fuel system can be a factor, in which case you should contact an Authorized Service Dealer.

Why is my Toro Lawn Mower cutting unevenly?
- M
  Melissa WhiteSep 6, 2025
  Uneven cutting height with your Toro Lawn Mower can be caused by several factors. Ensure that the blade(s) is sharp, if not, sharpen the blade(s). A bent cutting blade(s) will also cause this, so install a new cutting blade(s). Check if the mower is level from side-to-side and front-to-rear and level it if necessary. An incorrectly set anti-scalp wheel can also lead to uneven cutting, so adjust the anti-scalp wheel height. A dirty underside of the mower can interfere with cutting, so clean it. Incorrect tire pressure can also be a factor, so adjust the tire pressure. If a blade spindle is bent, contact an Authorized Service Dealer.
