What to do if KUHN Lawn Mower cutter bar is clogging?
- M
  Matthew SmithAug 15, 2025
  Cutter bar clogging in your KUHN Lawn Mower can occur due to several reasons. Dull or broken knives can cause clogging, so replace them if necessary. Check that the torque limiter is functioning and adjust the clutch. Too much cutterbar down pressure can also contribute; adjust the mowing unit ground pressure accordingly. Ensure the PTO speed is sufficient, increasing it if too low and verifying it matches the tractor's nominal speed. Lastly, stretched or worn belts can be a factor, so tighten or replace them.

Why does my KUHN FC250RG have frequent knife breakage?
- M
  Meredith ChenAug 18, 2025
  Frequent knife breakage on your KUHN Lawn Mower could stem from a few issues. The cutting height might be incorrect, so adjust it as needed. Excessive cutterbar down pressure can also cause this, so adjust the mowing unit ground pressure. Additionally, operating at excessive ground speed can lead to knife breakage, so reduce your speed.

What causes belt breakage in KUHN Lawn Mower?
- F
  fosterterriAug 21, 2025
  Belt breakage in your KUHN Lawn Mower can occur due to pulley misalignment; check that the pulleys are in line. An incorrectly positioned tensioning idler pulley can also cause this; check its alignment. Additionally, conditioning rotor vibration can lead to belt breakage, so inspect and replace any worn or damaged fingers on the conditioning rotor.

How to fix uneven stubble with KUHN FC250RG Lawn Mower?
- T
  Tanya SampsonAug 25, 2025
  If your KUHN Lawn Mower is leaving an uneven stubble, several factors could be at play. The knives may be dull or broken, requiring replacement. Ensure the knives are installed correctly, with the arrow on the knife's upper face pointing in the disc's rotation direction. Excessive ground speed can also cause this issue, so try reducing it. Check and adjust the cutting height and mowing unit ground pressure. In tangled or down crops, reduce the cutting height and increase ground pressure. Very wet conditions may also necessitate adjusting the mowing unit ground pressure and cutting height.

How to fix badly shaped windrows with KUHN Lawn Mower?
- C
  Christopher PughAug 30, 2025
  If you're experiencing badly shaped windrows with your KUHN Lawn Mower, several factors could be responsible. Slipping belts can cause this issue; retension them. Also, ensure that the PTO speed is sufficient, increasing it if it's too low and verifying that it corresponds to the tractor's nominal speed. Finally, check and adjust both swath shields, as incorrect adjustment can also lead to poorly shaped windrows.

What causes obstruction of conditioning rotor in KUHN FC250RG Lawn Mower?
- M
  Michelle RamirezSep 2, 2025
  Obstruction of the conditioning rotor in your KUHN Lawn Mower can arise from several causes. Check that the rotor drive belts are correctly tensioned, as insufficient rotor speed can lead to obstructions. Ensure the PTO speed is adequate, increasing it if too low and verifying it matches the tractor's nominal PTO speed. Open the swath shields if they are too closed. Finally, inspect the belts and tighten or replace the belts if they are stretched or worn.

Why KUHN FC250RG has considerable vibrations?
- K
  Katelyn WhiteSep 5, 2025
  Considerable vibrations in your KUHN Lawn Mower can be attributed to a distorted conditioning rotor, which would require replacement. Another cause could be distorted, worn, or missing rotor pivoting fingers, in which case you should inspect and replace any worn or damaged fingers on the conditioning rotor.

What causes soil build up in front of the KUHN Lawn Mower cutterbar?
- M
  mmitchellSep 8, 2025
  Soil build-up in front of the cutterbar of your KUHN Lawn Mower can be caused by too much cutterbar down pressure; adjust the mowing unit ground pressure. Very wet working conditions can also contribute, requiring adjustments to both the mowing unit ground pressure and the cutting height.
