Why is my Snapper 7800786 Lawn Mower cutting grass improperly?
- D
  Diana MillerAug 28, 2025
  If your Snapper Lawn Mower is cutting grass improperly, there are several potential causes. First, ensure that the tire pressure is even (15 PSI front tire & 12 PSI rear tire). Adjust the cutting height if it's too low or high. Make sure the engine speed isn't too slow by moving the throttle control to the 'FAST' position. If the forward speed is too fast, move the transmission shift lever to a slower speed. Adjust the side to side level if there's a terraced cut. Adjust the front to rear pitch if there's excessive deck pitch. Sharpen or replace dull or damaged cutting blades. Finally, adjust the tension or replace the mower belt if it's slipping.

Clean or replace the engine air pre-cleaner or air cleaner if they're dirty. Service the spark plug if it's faulty. Drain and clean the fuel system, and replace the filter, if there's water, debris, or stale fuel in it. Also, clean all debris from the engine cooling screen.

  Poor grass discharge from your Snapper Lawn Mower can occur for several reasons. Ensure the engine speed isn't too slow by moving the throttle control to the 'FAST' position.
