Why is my KUHN GMD 800 G II-HD leaving uneven stubble?
- B
  Bailey BrownAug 9, 2025
  Uneven stubble can occur for several reasons. It could be due to dull or broken knives, which require replacement. Ensure knives are installed correctly with the arrow on the upper face pointing in the disc's rotation direction. Check belts for correct tension if the disc speed is low. Increase engine speed to run the PTO at 540 rpm if the PTO speed is low. Finally, reduce tilt on the cutterbar if there is too much.

What to do if soil builds up in front of the KUHN Farm Equipment cutterbar?

  Soil buildup in front of the cutterbar can be addressed by adjusting the compensating spring tension if there's too much cutterbar down pressure. If working in very wet conditions, adjust the main frame height by shortening the chain as needed. Consider fitting a set of raised skids.

Why KUHN GMD 800 G II-HD cutterbar is not floating?
- D
  Daniel BlackAug 21, 2025
  If the cutterbar isn't floating, ensure the tractor spool valve is set to the float position, allowing the cylinder to move freely. Also, the compensating spring may need adjustment. Check the condition of the bevel gearbox mounting bushes and replace them if necessary, as wear or seizing can cause this issue.

  If the stubble is too long, adjust the cutterbar angle using the tractor top link. You may also need to adjust the compensating spring tension and main frame height if there is insufficient cutterbar down pressure.

Why is my KUHN Farm Equipment machine breaking back too easily?

  Evan SchwartzSep 1, 2025
  If the machine is breaking back too easily, it could be due to insufficient tension on the breakaway spring washers; tighten them. Alternatively, reduce the tractor's ground speed if it's excessive for the field conditions.
