Why is my Scag Power Equipment Lawn Mower streaking?

  Kimberly JimenezAug 4, 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, so start by sharpening the blades. Also, ensure the engine is running at full RPM. Check for belt slippage and adjust belt tension if needed. Grass accumulation under the deck can also cause this, so clean the underside of the deck. Avoid mowing wet grass, and slow down if your ground speed is too fast. Finally, inspect the blades for bending and replace them if necessary.

  David GilbertAug 12, 2025
  If your Scag Power Equipment Lawn Mower blades are hitting the dirt or cutting too close to the ground, check and adjust tire pressures, as low tire pressures can cause this. Reduce ground speed, especially on rough terrain, to adjust for conditions. It might be necessary to raise the cutting height or change the direction of cut. If the grass is wet, wait until it dries out before mowing. Adjust the pitch and level if cutting too low.

Why Scag Power Equipment TURF TIGER STT61V-27CH leaves an uneven cut on flat ground?
- J
  Jaclyn SingletonAug 16, 2025
  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, several factors could be at play. 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's too much blade angle. If the deck is mounted improperly or the spindle area is bent, consult your authorized SCAG dealer. Finally, sharpen the blade if it's dull.
