The bale basket isn't the problem.
Starting easy:
Start at the twine box with your fishing scale, same pull to get twine from both sides? Is the twine route correct?
Are the hay dogs working properly to keep the hay back?
Are your knives sharp, very sharp?
Are the bill hooks etc are smooth, polished looking? Is anything keeping the jaws from closing tight?
Next cycle your knotter by hand while rolling it over. Watch what is going on especially between the two sides. Is the wiper cleaning the knot off right? Was the twine picked up right from the needles at the first part of the cycle? Needles putting twine in the right notched area for the disc to pick up right? Twine disc timing the same side to side?
You may not have enough twine disc tension either from junk stuck in it keeping it spread open or a collapsed spring. Sisal can sometimes break and get stuck in the twine disc area. Clean it up, scape out old broken pieces. This can be a pain, swing the knotter frame up to check it out.
Its likely something simple if its doing it every single cycle. Intermittent stuff is a lot harder to figure out.
I've only ever had trouble with the knife side knotter on my 336 in 10's of thousands of bales. Needle location and twine disc timing early on, an later running the junk sisal they sell now. The sisal give uneven tension coming from the twine box and the lumps etc jam the knotter when it breaks. I don't like the plastic tails all over my property and clients property but I've found it ties far more reliable (missed 1 or 2 out of 5000+ this summer).
