      Martin LongAug 15, 2025
      If you're experiencing poor raking over the entire rotor width with your KUHN Lawn Mower, it could be that the tines are too far from the ground. Adjust the wheel height to correct this.

      Danielle CastilloAug 18, 2025
      If your KUHN Lawn Mower is raking poorly on one side of the rotor, it may be because the rotor is tilted towards the opposite side. Adjust the wheel height to ensure the same tine-to-soil distance on both sides of the machine.

    What to do if the torque limiter disengages frequently on my KUHN GA300GM Lawn Mower?
    • C
      Christine HamiltonAug 25, 2025
      If the torque limiter on your KUHN Lawn Mower disengages frequently, it indicates that the load on the tine arms is too high. To resolve this, adjust the wheel height. Alternatively, reduce the ground speed.

    Why is my KUHN Lawn Mower picking up crop at the rear of the rotor?
    • B
      Bruce RiceAug 28, 2025
      Crop pick up at the rear of the rotor of your KUHN Lawn Mower can occur due to several reasons. It may be caused by swaths that are too compact between the tines and the swath screen, in which case you should increase the swath screen distance. Another cause could be earth clods on the tines, which can be resolved by adjusting the wheel height. Finally, if the rotor speed is too high, reduce the PTO speed.

    What to do if my KUHN GA300GM has crop ejection at the front of the swath screen?
    • M
      michaelcareySep 4, 2025
      Crop ejection at the front of the swath screen on your KUHN Lawn Mower can occur if the swath screen position is incorrect, specifically if it's too much at the rear. To fix this, move the swath screen forwards. Reducing the PTO speed may also help.

    Why is my KUHN GA300GM ejecting crop underneath the swath screen?
    • J
      Jennifer CraigSep 7, 2025
      Crop ejection underneath the swath screen of your KUHN Lawn Mower is caused by an incorrect swath screen position. If it is too far away from the ground, move the swath screen downwards.
