OK... maybe not 743... but, it would seem that I've had more mystery issues with twine box tension on our old NH269 than I should.
The symptom is:
The twine comes out of the needle, but is still going through the baler. It usually runs along the bottom of the hay in the chamber.
This CAN be a twine disc/twine holder problem.... and/or a needle placement problem... had this problem last year... checked the discs and the needles.... all good.
Tightened the tension at the twine box? Fixed it.
The manual says that it needs about 10lbs of pull force.
Well, the problem came back this year. I checked the discs and the needle placement again. All good. I replaced the bolt on the twine clamp (it was old and rusty); so that I could tighten and adjust it better... the problem almost went away...
Almost.
What we reasoned out is this, the little clamp plate was twisting. I always hold it square when I adjust the tension, to make sure the tension is even on both sides. BUT... in use, the plate twists, covering one hole almost completely, keeping the twine nice and tight on that side.... but it almost uncovers the other hole... couple that with a little bit of wear at the hole edge... and when this happens, that particular twine has almost no tension on it.
So, took the cordless drill out to the field and drilled a hole in the plate... and installed a cotter pin... loose enough to not affect the clamping pressure, but just there to keep the plate from twisting.
Now? Six wagons loaded without a repeat of that problem. I think we finally got it...
