      If your Scag Power Equipment Lawn Mower is leaving occasional strips of uncut grass the width of the deck, several factors could be at play. Ensure the engine is running at full RPM. Adjust your ground speed to suit the conditions. Avoid cutting when the grass is wet; wait until it has dried out. Sharpen your mower blades, and clean any grass accumulation from the underside of the deck. Finally, check and adjust the belt tension to prevent slipping.

      Tammy McculloughAug 22, 2025
      If your Scag Power Equipment Lawn Mower blades are hitting the ground or dirt, it could be due to low tire pressures, so check and adjust them. The ground speed might be too fast, so slow down to adjust for conditions. You might be cutting too low, so reduce ground speed, raise the cutting height, change the direction of cut, and/or adjust the pitch and level. Also, avoid cutting wet grass; wait until it has dried out.

      If your Scag Power Equipment Lawn Mower is leaving a wavy appearance, scalloped cut, or rough contour, it could be due to several factors. If the lift is worn from the blade, replace it. Ensure the blade is mounted with the cutting edge toward the ground. Clean any grass accumulation from under the deck. Adjust the deck pitch and level if there's too much blade angle. For issues with deck mounting or a bent spindle area, consult your authorized SCAG dealer. Finally, sharpen the blade if it is dull.

      Mia TorresAug 26, 2025
      If you notice a ridge in the center of the cutting path with your Scag Power Equipment Lawn Mower, it could be due to unevenly mounted blades; adjust the pitch and level. A bent blade can also cause this, so replace it. For internal spindle failure or incorrect spindle mounting, it is recommended to consult your authorized SCAG dealer.

      If your Scag Power Equipment Lawn Mower is producing an uneven cut on uneven ground, resulting in a heavy appearance or high-low scalloped cut, it's likely due to the uneven ground itself.
