Adjust Twine Tension

TS679
TS679-UN-28SEP89

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 the tractor engine.

Twine arms can move unexpectedly. Keep hands out of the twine arm path to avoid crushing. Turn off power 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.

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

Left-Hand Twine Tension Plate Shown

A - Tension Plates

The spring-loaded tension plates (A) control the twine tension.

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

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

To adjust twine tension:

  1. Lower the pickup to prevent twine arm from bending pickup teeth.

  2. Move twine arms to home position. Make sure that twine is routed correctly. (See ROUTE TWINE in Preparing the Baler section.)

    Remove crop buildup from tension plates (A) on front panels and from tension plates (B) on twine arms.


  4. Attach a spring scale to the twine from the rear twine arm (C). Pull the twine perpendicular to the twine arm to check tension. If tension is not within specification:

    • Tighten wing nut (D) to increase tension on twine.
    • Loosen wing nut (D) to decrease tension on twine.
