    The twine breaks at the knot.  Sharp edges may be in the knife arm; smooth the knife arm or replace it. Or you may have too much bale tension; decreasing tension should fix it.

  • What Agassiz Experts Are Saying


    The knot did not strip off the billhook. Excessive billhook tension can cause this; decrease tension. Or the billhook may need replacing if it’s rough, worn or bent. Is the knife arm not rubbing the billhook? Adjust or replace it. If the knife arm does not travel far enough, check lobe in cam gear and knife arm roller.

Or the needle did not place twine in twine disc, so adjust the needle to specifications and check tensioner at twine box. See if hay dogs are malfunctioning.
