  If your Scag Power Equipment Lawn Mower is leaving strips of uncut grass in the cutting path, several factors could be at play. The blades might be dull or worn, or perhaps they were sharpened incorrectly, so sharpen the blades. Ensure the engine is running at full RPM. Slipping belts could also be the culprit, so adjust the belt tension. Grass accumulation under the deck can cause this issue; therefore, clean the underside of the deck. Avoid mowing wet grass and slow down your ground speed. Bent blades can also cause this problem, so replace the blades.

  If your Scag Power Equipment Lawn Mower occasionally leaves blades of uncut grass, also known as stringers, it could be due to several reasons. Ensure the engine is running at full RPM. Adjust your ground speed to suit the conditions. Avoid cutting wet grass; wait until it has dried out. Sharpen the blades. Clean the underside of the deck to remove any grass accumulation. Finally, adjust the belt tension to prevent slipping.

  If your Scag Power Equipment Lawn Mower is producing an uneven cut on flat ground, resulting in a wavy, high-low appearance, scalloped cut, or rough contour, consider these potential causes. If the lift is worn from the blade, replace the blade. Ensure the blade is mounted correctly with the cutting edge toward the ground. Clean the underside of the deck to remove any grass accumulation. Adjust the deck pitch and level. If the deck is mounted improperly or the spindle area is bent, consult your authorized SCAG dealer. Also, ensure that you sharpen the blade.

  If your Scag Power Equipment Lawn Mower is leaving a sloping ridge across the width of the cutting path, check and adjust the tire pressure to ensure it is equal on all tires. Also, ensure the wheels are even. If the deck is mounted incorrectly, consult your authorized SCAG dealer. Check if the deck is level side-to-side and correct if necessary.

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

  If your Scag Power Equipment Lawn Mower leaves strips of uncut grass in the cutting path, several factors could be responsible. The blades might be dull or worn, or they may have been sharpened incorrectly; in this case, you should sharpen the blades. Low engine RPM can also cause this, so ensure the engine is running at full RPM. A slipping belt requires adjusting the belt tension. Grass accumulation under the deck means you should clean the underside of the deck. Operating at a ground speed that's too fast or cutting wet grass can also lead to this issue; slow down or cut when the grass is dry. Finally, bent blades will need to be replaced.
