Adjusting Twine Arm-to-Starter Roll, Cutter Link Support, and Twine Arm Stop

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

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

NOTE: Adding or removing shims located between the twine arm support and crossbeam will affect dimensions at the following locations:

• Twine arm to starter roll:

  • Twine arm pointing directly toward rear.

  • Twine arm toward right side of baler.

  • Twine arm toward left side of baler.

• Twine arm to cutter link support.

• Twine arm to twine arm stop.

Check dimensions at all locations before making any adjustments. Adding or removing shims at one location may change the dimension at another location.

2. Shut off tractor engine and remove key. Lock the gate.

3. Remove lower drive roll chain so starter roll can be rotated by hand.

2. Rotate starter roll until starter roll rod (C) is closest to the twine arm tube.

3. By hand, remove end play at end of twine arm toward starter roll. Check dimension (B) between starter roll rod (C) and twine arm tube. Dimension (B) should be within specifications.

Specification

4. If dimension (B) is less than specified:

• Remove shims, as necessary, at location (D) between twine arm support and crossbeam. Remove an equal amount of shims at the right-hand and left-hand mounting bolts. One shim moves twine arm approximately 3 mm (1/8 in.).

  OR

• Add shims, as necessary, at location (E) between twine arm support and crossbeam. Add an equal amount of shims at the right-hand and left-hand mounting bolts.

5. If dimension (B) is more than specified:

• Remove shims, as necessary, at location (E) between twine arm support and crossbeam. Remove an equal amount of shims at the right-hand and left-hand mounting bolts. One shim moves twine arm approximately 3 mm (1/8 in.)

  OR

• Add shims, as necessary, at location (D) between twine arm support and crossbeam.

7. Rotate starter roll until starter roll rod (B) is closest to twine arm strap (A).

8. By hand, remove twine arm end play at end of twine arm toward starter roll.

9. Check dimension (C) between starter roll rod (B) and strap (A). Dimension (C) should be to specifications.

Specification

10. If dimension (C) is less than specified, add an equal number of shims at right-hand location (D and E), or remove an equal number of shims at left-hand location (D and E).

11. Move twine arm left of center so strap (A) is below starter roll rod (B).

2. Check dimension (C) between top of twine arm strap and bottom edge of cutter link support (B). Dimension (C) should be within specifications.

Specification

3. If dimension (C) is less than specified and no shims exist at location (D) between support (B) and crossbeam:

• Add an equal number of shims between twine arm support and crossbeam at left-hand locations (E and F).

  OR

• Remove an equal number of shims between twine arm support and crossbeam at right-hand locations (E and F).
