How to fix an uneven cut with my Craftsman Lawn Mower?
- J
  james38Aug 2, 2025
  An uneven cut from your Craftsman Lawn Mower can typically be attributed to a few common problems: * **Blade Condition**: Check the blade for wear, bending, or looseness. Replace the blade if necessary and tighten the blade bolt. * **Wheel Height**: Ensure all wheels are set at the same height. Uneven wheel heights will cause an uneven cut. * **Underside Buildup**: Buildup of grass, leaves, and trash under the mower can interfere with the blade's performance. Clean the underside of the mower housing.

Why does my Craftsman Lawn Mower lose power?
- J
  Jennifer CarrAug 6, 2025
  A loss of power in your Craftsman Lawn Mower can stem from several issues: * **Grass Height**: If the rear of the mower housing or the blade is dragging in heavy grass, or you're cutting too much grass at once, raise the cutting height. * **Air Filter**: A dirty air filter restricts airflow, reducing engine power. Clean or replace it. * **Underside Buildup**: Accumulated grass, leaves, and trash under the mower housing can impede performance. Clean the underside of the mower. * **Oil Level**: Too much oil in the engine can also cause power loss. Check the oil level and adjust if necessary. * **Walking Speed**: If you're walking too fast, the mower might struggle. Try cutting at a slower pace.

  If the starter rope on your Craftsman Lawn Mower is difficult to pull, consider the following: * **Control Bar**: Ensure the control bar is depressed to the upper handle before pulling the starter rope. The engine flywheel brake might be engaged if the control bar is released. * **Blade**: The blade dragging in grass can make the rope hard to pull. Move the mower to cut grass or to a hard surface. * **Blade Adapter**: A broken blade adapter can cause resistance. Replace the blade adapter if it's damaged.
