Ensure that the twine is threaded correctly and does not pull too hard. See the appropriate operator's manual to confirm twine routing.
NOTE: Twine of a lesser quality may loose fiber, which builds up and increases the drag of the twine
Check, and if required, adjust the twine tensioners inside the twine boxes to a spring length of 26 mm +/- 1.5 mm (1 inch +/- 1/16 inch).
Replace the pig tail spring type twine guides (part number 86618572) (if equipped) with the formed twine guides (part number 86637283).
Ensure that the twine is properly cut:
- make sure that the twine knives are sharp and parallel to their striker
- avoid crop accumulation on the twine knives
Ensure that the twine actuator is correctly calibrated (insert position - precut position - home position).
Ensure that the loose end of twine is long enough to touch the bale. Adjust the length of the loose twine by adjusting the length of the drag link between twine actuator and twine arms.
Ensure that the loose end of twine is not too long, otherwise it will hang-up against the cross beam of the rotor frame while being inserted instead touching the bale. Adjust the length of the loose twine by adjusting the length of the drag link between twine actuator and twine arms.
Continuing to feed crop for a couple of meters (yards) until the twine has started to run, will help in most conditions.
On stuffer units the crop will help to feed the twine to the bale. On rotor units the fresh crop will help to make the surface of the bale rougher.
