How to fix stringers (occasional blades of uncut grass) with my Scag Power Equipment Tiger Cat II STCII-52V-26FT-EFI?
- G
  Gabrielle RodriguezAug 15, 2025
  If your Scag Power Equipment Lawn Mower is leaving occasional blades of uncut grass, it could be due to several reasons. Ensure the engine is running at full RPM. If your ground speed is too fast, slow down to adjust for the conditions. Avoid cutting wet grass; wait until it has dried out. Check if the blades are dull or incorrectly sharpened and sharpen them if needed. Also, inspect the deck for grass accumulation and clean the underside if necessary. Finally, check for belt slippage and adjust the belt tension if needed.

Why does my Scag Power Equipment Tiger Cat II STCII-52V-26FT-EFI Lawn Mower leave a sloping ridge?
- W
  Wendy FerrellAug 18, 2025
  If your Scag Power Equipment Lawn Mower is leaving a sloping ridge across the width of the cutting path, start by checking and adjusting the tire pressure to ensure they are equal. Also, inspect the wheels for unevenness and adjust the tire pressure accordingly. If the deck is mounted incorrectly, consult your authorized SCAG dealer. Finally, check if the deck is level from side to side and correct it if necessary.

What to do if my Scag Power Equipment Tiger Cat II STCII-52V-26FT-EFI Lawn Mower is streaking?

  Taylor GatesAug 21, 2025
  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, requiring sharpening. Incorrect blade sharpening can also cause this issue, so ensure they are properly sharpened. Other potential causes include low engine RPM (run the engine at full RPM), a slipping belt (adjust belt tension), grass accumulation under the deck (clean the underside of the deck), ground speed being too fast (slow down), wet grass (cut when dry), or bent blades (replace blades).

  Erik JacksonAug 26, 2025
  If your Scag Power Equipment Lawn Mower blades are hitting the dirt or cutting too close to the ground, check the tire pressures and adjust them if they are low. Reduce ground speed if it's too fast. You may also need to raise the cutting height, change the direction of cut, and/or adjust the pitch and level. Avoid cutting wet grass and wait until it has dried out. Also, consider that rough terrain may require adjustments to ground speed, cutting height, and cutting direction.

Why is my Scag Power Equipment Tiger Cat II STCII-52V-26FT-EFI Lawn Mower cutting unevenly on flat ground?
- D
  Debbie HerreraAug 28, 2025
  If your Scag Power Equipment Lawn Mower is producing an uneven cut on flat ground, resulting in a wavy high-low appearance, several factors could be responsible. Check the blade for wear and replace it if the lift is worn. 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 there's too much blade angle. If the deck is mounted improperly or the spindle area is bent, consult your authorized SCAG dealer. Finally, ensure the blade is sharp; sharpen if dull.

  velezthomasSep 8, 2025
  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.

  If your Scag Power Equipment Lawn Mower is leaving strips of uncut grass between cutting paths, this may be due to not enough overlapping between rows. Increase the overlap of each pass to resolve this issue.
