Adjusting Twine Tension

causym CAUTION: To avoid injury or death by being pulled into the machine:

DO NOT attempt to feed twine into baler or pull twine from twine arms WHILE BALER IS RUNNING. The baler feeds material faster than you can release it.

Disengage PTO and shut off tractor engine.

Twine arms can move unexpectedly. Keep hands out of twine arm path to avoid crushing. Turn off power to twine arms BEFORE servicing or adjusting twine arms or twine cutter mechanism.

Stay out of the path of twine arms at all times when power to twine arms is ON.

NOTE: It may be necessary to adjust twine tension when changing to a different size twine or when changing from sisal to plastic.

Left-hand side (front arm) shown. Right-hand side (rear arm) tension plates are the same.

Twine tension is controlled by spring-loaded tension plates (A).

Adjust twine tension while pulling twine perpendicular to end of twine tube.

  • If twine tension is too high, the twine may not start to wrap around the bale or twine may break.
  • If twine tension is too loose, the twine may not hold the bale adequately.

To adjust twine tension:

1. Lower pickup to avoid twine arm from bending pickup teeth.
