Adjust Twine Tension

CAUTION:

TS679-UN-28SEP89

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.

E47598-UN-07JAN00

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

NOTE: It can 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.

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 pickup to avoid twine arm from bending pickup teeth.

2. Move twine arms to home position. Make sure that twine is routed correctly. (See ROUTE TWINE—RIGHT-HAND SIDE [REAR ARM] and LEFT-HAND SIDE [FRONT ARM] in Preparing the Baler section.)

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

5. Repeat Step 4 to adjust twine tension for front twine arm (E).
