CAUTION: Twine arms can move unexpectedly when twine arm power is on. Turn off power to twine arms when standing or placing hands near twine arms.

Twine knife has two cutting edges. Be careful when working around the knife. It is sharp.

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 performing adjustments. Adding or removing shims at one location can change the dimension at another location.

  1. Start tractor engine and raise gate fully.

  2. Lower pickup so twine arms will not contact pickup teeth.

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

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

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

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

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

    • Remove shims, as necessary, at location (E) between twine arm support and crossbeam. Remove an equal number 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.

  14. 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).

  15. Turn tractor key to ON position. Turn monitor-controller ON.

  16. Press monitor-controller RETRACT key to move twine arm left of center so strap (A) is below starter roll rod (B).

  17. Turn monitor-controller OFF. Turn tractor key to OFF position. Remove key.

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

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

Check twine arm adjustments

  1. Check clearances again between twine arm and starter roll, twine arm and cutter link support, and twine arm to twine arm stop. If twine arm to starter roll dimension has changed due to adjusting twine arm to cutter link support or twine arm stop, adjust shims between twine arm and crossbeam as needed.

  2. Adjust twine cutter-to-twine arm. (See ADJUST TWINE CUTTER-TO-TWINE ARM in this section.)

  3. Install lower drive roll chain.
