Adjusting Twine Tension

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 arm(s) can move unexpectedly when twine arm power is on. Stay out of the path of twine arm(s) at all times when twine arm power is on. During service or adjustment procedures for twine arm(s) or twine cutter mechanism, turn off power to twine arm(s) BEFORE placing your hands in the path of twine arm travel.

If there is crop material which is holding twine arm(s) from moving freely during twine arm cycle, it is recommended that twine arm(s) be manually positioned to release any "hold" they may have on the crop material. Turn off power to twine arm(s). This will help to make the unplugging operation easier and prevent twine arm(s) from moving unexpectedly while your hands may be in the path of the twine arm(s). Stay out of the path of twine arm(s) at all times when power to twine arm(s) 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 to specifications 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(s) from bending pickup teeth.

2. Move twine arm(s) to home position. Make sure twine is routed correctly. (See ROUTING TWINE-RIGHT-HAND SIDE [REAR ARM] AND LEFT-HAND SIDE [FRONT ARM-IF EQUIPPED] in Preparing the Baler section.)

3. Remove crop buildup from tension plates (A) located on door bands and from tension plates (B) located on twine arm(s).

4. Attach spring scale to twine from rear twine arm (C). Pull twine perpendicular to the twine arm. Twine pull should be within specifications.

Specification

• 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), if equipped.

6. Cut twine 305-381 mm (12-15 in.) beyond end of twine arm(s) (C and E).
