Bought a JD 327 with the knotters broken. I have it all back together. We baled some with it this week. It will tie a perfect knot if you crowd the heck out of it. Baling like normal it will pull some of the strands of twine back through the knot. Not the whole twine just about a 1/3 of one string.(the knot in the picture is the full string fold back into the knot. This is not what I have. I just have a few strands of one twine) Not completely through just folded and back under the twine. This makes that knot be loose. About half of them will break when the ejector throws the bale. Only the right knotter doing this. Left ties perfectly.
Sisal twine or plastic. It does it on both.
The bill hooks are new. I have polished them to make double sure they do not have a burr on them to catch the twine. They hold the knot and twine fine.
Wiper arms are set correctly. Never have a knot left on the bill hook.. The twine knives are razor sharp and cutting square ends.
The little bit that is folded is cut.
At hand speed the knotter will tie a perfect knot every time. At PTO speed without any hay it will tie perfectly. When in hay it will tie 90% perfectly. 10% folded and 10% of them break. So it is a real low number that break.
I have rarely had one that would tie fine slow and then not when at speed.
It is almost like the tongue is spearing part of the twine when it grabs the twine. It clears fine slow and fast you can't see what is happening as it ties.
I am stumped as to what to try next. It is not the one string folded. I have had that happen and it is usually the wiper arm not centered correctly over the bill hook. The tails are long enough too. I first thought it was pulling a tail back through the knot. I watched the bales and found some that held and then untied the knot. You can see the few strands of sisal folded and tucked under the knot.
