    What to do if MacDon R1 cutterbar is plugging?
    • J
      Jessica CurtisAug 11, 2025
      If the cutterbar is plugging, several factors could be at play. It might be that the blades are dull, bent, or badly worn, in which case you should replace them. Another cause could be a build-up of dirt between the rock guards, so decreasing the mower conditioner angle and increasing flotation might help. In some cases, it may be necessary to carry the mower conditioner slightly with lower skid shoes. Finally, the conditioner drive belt might be slipping, requiring you to adjust the conditioner drive belt tension.

    Why MacDon R1 leaves strips of uncut crop on the field?

      Charles HendersonAug 21, 2025
      Leaving strips of uncut crop on the field can happen for a few reasons. Check for bent or dull cutter blades and replace them if needed. A build-up of dirt between the rock guards can also cause this, so decrease the mower conditioner angle and increase flotation. Make sure your ground speed isn't too slow; if it is, increase it. Also, disengage the mower conditioner and stop the engine to remove any foreign object from the cutterbar.

    How to fix ragged or uneven cutting of crop with MacDon Farm Equipment?
    • T
      Tracy ReedSep 1, 2025
      Ragged or uneven cutting of crop could be due to several reasons. If the mower conditioner flotation is too light, causing bouncing, adjust to a heavier float setting. Excessive ground speed can also be a factor, so reduce ground speed. If you're dealing with downed crop, adjust the mower conditioner angle to cut closer to the ground.
