  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.

  Streaking, or strips of uncut grass in the cutting path, can occur for several reasons. The blades may be dull or worn, or they may have been sharpened incorrectly; in this case, sharpen the blades. The engine RPM might be too low, so ensure the engine is running at full RPM. A slipping belt can also be the cause, so adjust the belt tension. Check for grass accumulation under the deck and clean it if necessary. If you are mowing too fast for the conditions, try slowing down. Cutting wet grass can also cause this issue, so wait until the grass is dry. Bent blades can also cause this problem, so replace them.

What to do if my Scag Power Equipment Liberty Z SZL36-18FR is scalping, hitting dirt, or cutting too close to the ground?
- R
  rfoxAug 28, 2025
  Scalping, where the blades hit the dirt or cut very close to the ground, can be caused by several factors. Check and adjust the tire pressures, as low tire pressures can cause this. If your ground speed is too fast, slow down to adjust for conditions. You might be cutting too low, so consider raising the cutting height. Rough terrain can also cause scalping, so you may need to reduce ground speed, raise the cutting height, or change the direction of cut. Also, avoid cutting wet grass.

Why is my Scag Power Equipment Liberty Z SZL36-18FR Lawn Mower leaving an uneven cut on flat ground?
- J
  Justin WilsonSep 2, 2025
  An uneven cut on flat ground, resulting in a wavy, high-low appearance, scalloped cut, or rough contour, can be due to several issues. 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 any grass accumulation from the underside of the deck. Adjust the deck pitch and level if there is too much blade angle. If the deck is mounted improperly or the spindle area is bent, see your authorized SCAG dealer. Dull blades can also cause this, so sharpen the blade.

  Elizabeth RobertsonSep 12, 2025
  If you're experiencing an uneven cut (wavy appearance, high-low scalloped cut, or rough contour) while mowing on uneven ground with your Scag Power Equipment Lawn Mower, the primary cause is the uneven ground itself. To mitigate this, you may need to reduce ground speed, raise the cutting height, and/or change the direction of cut.
