  If your Scag Power Equipment Lawn Mower is leaving strips of uncut grass in the cutting path, several factors could be the cause. Dull or worn blades, incorrect blade sharpening, low engine RPM, a slipping belt, a plugged deck due to grass accumulation, excessive ground speed, wet grass, or bent blades could all contribute to this issue. To resolve this, start by sharpening or replacing the blades. Ensure the engine is running at full 3600 RPM. Adjust the belt tension and clean the underside of the deck. Reduce your ground speed and only cut when the grass is dry.

  If your Scag Power Equipment Lawn Mower is leaving occasional blades of uncut grass, this could be due to several reasons. The engine RPM might be too low, or the ground speed might be too fast. Wet grass, dull blades, incorrect sharpening, grass accumulation under the deck, or slipping belts could also be factors. To fix this, run the engine at full 3600 RPM and slow down to adjust for the conditions. Cut grass after it has dried out, sharpen the blades, clean the underside of the deck, and adjust the belt tensions.
