What to do if Scag Power Equipment STC61V-27CV-SS Lawn Mower has uneven cut on flat ground?
- T
  Taylor RossAug 20, 2025
  If your Scag Power Equipment Lawn Mower is producing an uneven cut on flat ground, several factors could be the cause. A worn lift on the blade means you should replace the blade. Check to see if the blade is upside down and mount it with the cutting edge toward the ground. If the deck is plugged with grass accumulation, clean the underside of the deck. If there is too much blade angle (deck pitch), adjust the pitch and level. For issues related to an improperly mounted deck or a bent spindle area, consult your authorized SCAG dealer. Also, check if the blade is dull and sharpen it if needed.

  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 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.

  Ian KnappSep 2, 2025
  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.

Why is my Scag Power Equipment STC61V-27CV-SS streaking?
- J
  James HarrisSep 4, 2025
  If your Scag Power Equipment Lawn Mower is streaking, leaving strips of uncut grass in the cutting path, several factors could be at play. You might have dull or worn blades, or they may be incorrectly sharpened, so try sharpening the blades. The engine RPM might be too low; ensure it's running at full RPM. Also, check for a slipping belt and adjust the belt tension if needed. Grass accumulation under the deck could be the cause, so clean the underside of the deck. Cutting wet grass or moving too fast can also lead to this issue, so cut when the grass is dry and slow down. Finally, inspect the blades for bending and replace them if necessary.

  Frank CollinsSep 6, 2025
  If your Scag Power Equipment Lawn Mower leaves stringers, or occasional blades of uncut grass, several factors could be the cause. 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 your blades; dull or incorrectly sharpened blades need sharpening. A plugged deck due to grass accumulation requires cleaning the underside of the deck.
