Why is my MacDon R85 leaving ragged or uneven cutting of crop?
- R
  rebeccaramirezSep 8, 2025
  Ragged or uneven cutting may occur due to several reasons. The header float may be too light, causing bouncing, so adjust to a heavier float setting. Excessive ground speed can also cause this issue, so reduce your speed. If the header angle is too flat, preventing the guards from picking up down crop, increase the header angle. You may also need to adjust the header angle to cut closer to the ground.

What to do if there are strips of uncut crop left on the field with MacDon Farm Equipment?

  If you notice strips of uncut crop left on the field when using your MacDon Farm Equipment, several factors could be at play. Start by checking for bent cutter blades and replace them if necessary. A build-up of dirt between the rock guards could also be the culprit, so decrease the header angle and increase flotation. Ensure your ground speed isn't too slow by increasing it, and conversely, avoid excessive header speed by reducing the header disc speed. Lastly, check for any foreign objects on the cutterbar; if found, disengage the header, stop the engine, and carefully remove the object once all moving parts have completely stopped.

Why are the conditioner rolls plugging on my MacDon R85?

  If the conditioner rolls on your MacDon Farm Equipment are plugging, several factors could be responsible. It might be that your ground speed is too fast, so try reducing it. The roll gap might be too large or too small for proper feeding; decrease the roll gap if it's too large, or increase it if you're working with thick-stemmed cane-type crops. Also, check the baffle setting; if it's too low, raise it. Ensure the roll speed isn't too low by increasing the disc speed. Finally, inspect for any foreign objects between the rolls, and if you find any, disengage the header, stop the engine, and remove the object once all moving parts have completely stopped.

How to resolve ragged cutting of crop with MacDon R85?

  If you are experiencing ragged or uneven cutting of crop with your MacDon Farm Equipment, it could be due to a few reasons. The header angle might be too flat for the guards to pick up down crop, so try increasing the header angle. Alternatively, the header flotation might be too light, causing bouncing; adjust to a heavier float setting. Excessive ground speed can also cause this issue, so reduce your ground speed. If you're dealing with downed crop, adjust the header angle to cut closer to the ground.

What to do if the MacDon Farm Equipment cutterbar is plugging?
- L
  Laurie OwensAug 27, 2025
  If the cutterbar is plugging, several factors could be at play. It could be due to dull, bent, or badly worn blades, in which case you should replace the blades. A build-up of dirt between rock guards might also be the cause; decrease the header angle and increase flotation. In some situations, carrying the header slightly with header lift cylinders may be necessary. Finally, check the conditioner drive belt; if it's slipping, adjust the conditioner drive belt tension.

  Several factors can cause strips of uncut crop. The issues could be bent cutterblades, so replace them. There could be a build-up of dirt between rock guards; decrease the header angle and increase flotation. Excessive header speed may be the problem, so reduce header disc speed. A foreign object on the cutterbar could be the culprit; disengage the header and stop the engine, then remove the object when all moving parts have completely stopped. If the disc is not turning, replace the spindle key. Also, check the ground speed, as it may be too slow; increase ground speed.

  If the cutterbar is plugging, several factors could be at play. Start by checking for dull, bent, or badly worn blades and replace them if needed. Also, inspect the auger drive belt for slippage, and adjust the tension or change the belts. Finally, if dirt builds up between the rock guards, decrease the header angle, increase float, and consider using header lift cylinders to carry the header slightly.

Check for any foreign objects on the cutterbar; if found, disengage the header, stop the engine, and remove the object once all moving parts have stopped. A disc not turning due to a faulty spindle key can also cause uncut strips, so replace the spindle key. Finally, if your ground speed is too slow, increase it to ensure a clean cut.

  Cutterbar plugging in your MacDon Farm Equipment can stem from several causes. Dull, bent, or badly worn blades can lead to this issue, so you should replace the blades. A build-up of dirt between rock guards can also cause plugging; decrease the header angle and increase flotation to resolve this. In some cases, you may need to use header lift cylinders to carry the header slightly. If the conditioner drive belt is slipping, adjust the conditioner drive belt tension.
