Operating Wrap Control-Hydraulic Actuated Twine Arm(s)

IMPORTANT: Wrap cycle should be started while traveling forward and baling. This allows twine to catch on the bale.

Start wrapping when the first audible alarm stops, indicating full size bale, and before the second alarm, indicating oversize bale.

NOTE: Keep engine speed constant while wrapping. Varying engine speed will change number of twine wraps and their spacing across the bale. When baling dry straw, it will be desirable to quickly place twine across full width of bale to prevent straw from coming out of feed opening while tying. If equipped with double twine arms; Open flow control valve completely.

Examples show operation of John Deere 7000 Series Tractor.

1. Push forward and hold SCV lever (A) until pointer reaches position (B). Stop forward travel when spinner(s) (C) show twine is caught on bale and moving.

2. Release lever for four to six seconds to apply right-hand end wraps.

NOTE: If equipped with double twine arms; Baler flow control valve regulates twine arm speed as it moves across the bale to provide equally spaced twine wraps.

3. Pull and hold lever rearward to bring twine arm(s) back across bale. Single twine arm; Position twine arm at index marks for approximately two to three seconds before advancing to next index mark. Adjust position and pause time to achieve desired twine spacing.

When bailing dry straw:

  • Push forward and hold SCV lever until pointer reaches (B) again.
  • Pull on SCV lever to position twine arm(s) at each index mark for approximately two to three seconds.

4. When pointer reaches the last index mark, release lever for four to six seconds to apply left-hand end wraps.
