Why does my Toro 74943 Lawn Mower produce an uneven cutting height?
- S
  Susan HarrisSep 1, 2025
  An uneven cutting height with your Toro Lawn Mower can be caused by several factors. The blades might not be sharp, so sharpen them. Bent cutting blades can also cause this issue, so install new ones if necessary. Ensure the mower deck is level from side-to-side and front-to-rear. Clean the underside of the mower, as dirt buildup can interfere with cutting height. Adjust the tire pressure to the correct level. For a bent blade spindle, contact an Authorized Service Dealer.

Why is my Toro Lawn Mower engine losing power?
- J
  Jessica RoseSep 1, 2025
  Your Toro Lawn Mower engine may lose power for several reasons. First, the engine load might be excessive, so reduce the ground speed. A dirty air cleaner can also cause power loss, so clean the air-cleaner element. Ensure the oil level in the crankcase is sufficient by adding oil if it's low. Lastly, check if the cooling fins and air passages above the engine are plugged and remove any obstructions.
