Why does my McCulloch MC20H42YT have poor grass discharge?
- F
  Felicia MillerAug 30, 2025
  If your McCulloch Lawn Mower has poor grass discharge, ensure the engine speed isn't too slow by placing the throttle control in the 'FAST' position. Check that your travel speed isn't too fast and shift to a slower speed if needed. Avoid mowing wet grass, and make sure the mower deck is level. Inspect the tires for proper air pressure. Check the blade; replace it if it's worn, bent, or loose, and tighten the blade bolt. Clean any buildup of grass, leaves, or trash under the mower. If the mower drive belt is worn, replace it. Ensure the blades are installed with the sharp edge down. If you're using improper blades, replace them with the blades listed in the parts manual. Finally, clean around the mandrels to open vent holes if they are clogged.
