Why is my Scag Power Equipment Lawn Mower leaving strips of uncut grass?

  christopher17Aug 13, 2025
  If your Scag Power Equipment Lawn Mower is leaving strips of uncut grass in the cutting path, several factors could be responsible. The blades may be dull or worn, or they might be incorrectly sharpened; in either case, sharpen the blades. The engine RPM might be too low, so ensure you run the engine at full RPM. A slipping belt can also cause this issue, adjust the belt tension. The deck could be plugged with grass accumulation, so clean the underside of the deck. The ground speed might be too fast, so slow down to suit the conditions. Cutting wet grass can also cause this, so cut the grass after it has dried out. Finally, bent blades can cause this issue, so replace the blades.

  If your Scag Power Equipment Lawn Mower is leaving occasional blades of uncut grass, several factors could be the cause. Make sure the engine is running at full RPM. If the ground speed is too fast, slow down to adjust for conditions. Avoid cutting wet grass; wait until it has dried out. Ensure the blades are sharp and correctly sharpened. A plugged deck due to grass accumulation can also cause this, so clean the underside of the deck. Finally, check for slipping belts and adjust the belt tension if necessary.

What to do if Scag Power Equipment SZL-36H-18FR Lawn Mower blades are scalping?

  If your Scag Power Equipment Lawn Mower blades are hitting the dirt or cutting too close to the ground, check the tire pressures and adjust them if they are low. Reduce ground speed to adjust for conditions if it's too fast. If you are cutting too low, you may need to reduce ground speed, raise the cutting height, change the direction of cut, and/or adjust the pitch and level. This issue can also be caused by rough terrain, so you may need to reduce ground speed, raise the cutting height, and/or change the direction of cut. Avoid cutting wet grass; cut after it has dried out.

Why is my Scag Power Equipment SZL-36H-18FR Lawn Mower cutting unevenly on flat ground?
- D
  David PorterAug 25, 2025
  If your Scag Power Equipment Lawn Mower is leaving an uneven cut on flat ground, resulting in a wavy, high-low appearance, scalloped cut, or rough contour, several factors could be responsible. A worn lift from the blade can cause this, so replace the blade. Ensure the blade is not upside down; mount it with the cutting edge toward the ground. A deck plugged with grass accumulation can also cause this, so clean the underside of the deck. If there's too much blade angle (deck pitch), adjust the pitch and level. For issues related to the deck being mounted improperly or a bent spindle area, consult your authorized SCAG dealer. Finally, a dull blade can also cause an uneven cut, so sharpen the blade.

  Javier AtkinsonAug 28, 2025
  If your Scag Power Equipment Lawn Mower is leaving a sloping ridge across the width of the cutting path, start by checking and adjusting the tire pressure, ensuring they are equal. Also, check the wheels for unevenness and adjust the tire pressure accordingly. If the deck is mounted incorrectly, consult your authorized SCAG dealer. Lastly, ensure the deck is level side-to-side and correct it if it is not.

  Samantha WilliamsSep 5, 2025
  If your Scag Power Equipment Lawn Mower is creating a ridge in the center of the cutting path, it could be due to several reasons. Ensure the blades are mounted evenly and adjust the pitch and level if necessary. A bent blade can also cause this, so replace the blade. For internal spindle failure or incorrect mounting of the spindle, consult your authorized SCAG dealer.

  estradaconnieSep 8, 2025
  If your Scag Power Equipment Lawn Mower is leaving an uneven cut on uneven ground, resulting in a wavy appearance, high-low scalloped cut, or rough contour, the cause is likely the uneven ground itself. You may need to reduce ground speed, raise the cutting height, and/or change the direction of cut to improve the cut quality.
