    Why is my Gehl Lawn Mower crop being pushed forward before cutting?
    • M
      Madison LeAug 1, 2025
      If the crop is being pushed forward before being cut, it could be due to wind turbulence created by the knives, especially when working in a very light crop. To resolve this, try reducing the PTO speed or increasing your forward speed.

    What to do if Gehl Lawn Mower has uneven stubble?
    • A
      Amanda WilsonAug 6, 2025
      Uneven stubble can occur for several reasons. Check the following: * The cutting height may be set too low. * The PTO speed may be too low. * The disc speed may be too low. * The forward speed may be too high. * The knives may not be installed correctly or are dull/broken. To fix this, adjust the top link on the tractor's 3-point hitch to increase the cutting height, ensure the PTO runs at 540 RPM, check drive belts for proper tension, reduce forward speed, install knives with arrows pointing in the direction of disc rotation, and replace dull or broken knives.

    Why Gehl Lawn Mower machine breaking back too easily?
    • A
      Annette WrightAug 11, 2025
      If the machine is breaking back too easily, it's likely due to insufficient tension on the break-away spring. To fix this, adjust the break-away spring washer stack tension.

    Why Gehl Lawn Mower stubble is too long?
    • J
      Jason MartinAug 17, 2025
      If the stubble is too long, it could be that the cutting height is set too high or there's too much cutterbar down pressure. Adjust the top link on the tractor's 3-point hitch to decrease the cutting height. Also, adjust the compensating spring tension.

    What to do if Gehl Lawn Mower has soil build-up on front of cutterbar?
    • A
      adam16Aug 21, 2025
      Soil build-up on the front of the cutterbar can be caused by very wet conditions or too much cutterbar down pressure. Adjust the main frame height to increase the distance between the lower hitch pins and the ground. Also, adjust the compensating spring tension.
