Why is my KUHN GMD 802 F leaving uneven stubble?
- L
  Lisa LeeAug 7, 2025
  Uneven stubble can occur for several reasons. It may be due to too much tilt on the cutterbar, low PTO speed, knives not installed correctly (ensure the arrow on the knife upper face points in the disc's rotation direction), or worn/dull knives (replace knives). To fix this, reduce the cutterbar tilt, increase the engine speed to run the PTO at the correct RPM, check knife installation, and replace worn knives.

Why is there poor crop flow over the cutterbar of my KUHN GMD 802 F Lawn Mower on slopes?
- A
  Ariel BrandtAug 17, 2025
  Poor crop flow over the cutterbar when mowing on slopes at a low forward speed is likely due to a PTO speed that is too high. Reduce the PTO speed by a third to correct this.

  If the stubble is too long, the cutterbar angle is likely incorrect. Reduce the cutterbar angle to fix this.

Why KUHN GMD 802 F Lawn Mower has incorrect adaptation to ground contours?
- S
  Shawn FullerSep 1, 2025
  Incorrect adaptation to ground contours can be caused by several factors. These include incorrect frame adjustment, excessive forward speed, insufficient air pressure in the lifting cylinders (increase the pressure), or the tractor’s single acting hydraulic valve not being in the free floating position (shift the valve to the free floating position).
