    What causes uneven reel motion or stalling in heavy crop for MacDon Farm Equipment?
    • K
      Kristopher JacobsonSep 5, 2025
      If the reel motion is uneven or stalls in heavy crop with your MacDon Farm Equipment, try the following: Reduce reel speed if it's too fast. Move to a more aggressive finger pitch notch if the reel fingers aren't aggressive enough. Raise the reel if it's too low. Increase the relief pressure to the manufacturer’s recommendations if the relief valve on the windrower has a low relief pressure setting. Fill to the proper level if there is a low oil reservoir level on the windrower. Replace the relief valve if it is malfunctioning. Replace with a high torque reel drive sprocket if you are cutting tough crops with a high-speed reel drive sprocket.

    Why is the windrow uneven with my MacDon D50 Farm Equipment?
    • T
      Tammy JordanSep 5, 2025
      If you're experiencing an uneven windrow with your MacDon Farm Equipment, it could be due to a few reasons. If the ground speed is too fast for the drapers, reduce ground speed or increase draper speed. The reel might be too low, so raise it. Alternatively, the reel might be too fast, so reduce its speed.

      Phillip HallAug 25, 2025
      Heads shattering or breaking off in your MacDon Farm Equipment can occur if the reel speed is too fast, the reel is too low, or the ground speed is too fast. To resolve this, reduce the reel speed, raise the reel, or reduce the ground speed. Operating at night when humidity is higher can also help if the crop is too ripe.

    Why is cut grain falling ahead of the cutterbar on my MacDon D50?
    • W
      wlambSep 3, 2025
      If cut grain is falling ahead of the cutterbar on your MacDon Farm Equipment, consider these solutions. Increasing ground speed may help, as well as increasing reel speed. The reel or cutterbar may be too high, so lower them. If the reel is too far forward, move it back on the arms. If cutting at speeds over 6 mph with a high-torque reel drive sprocket, replace it with a high-speed reel drive sprocket. Finally, replace any worn or broken sickle components.
