Hello.
NH 315 Baler - if it ain't broke, don't fix it!
Had a drive yoke failure, and thought it wise to rebuild the knotters. It was tying decently before, with little failures (maybe 1 failure out of 500), but the pinions and worm screw were badly worn; the roller was more square than round, and the fingers (or more precisely the finger holders) had pretty much disintegrated. I also replaced the bill hooks (mainly because of the bill hook tongues), and replaced a complete knotter frame, as I cracked it trying to get the bill hook pinion off.
When I came to bale hay, it missed knotting at a much higher rate than before. It now missed maybe 1 out of 40 bales.
I thought I checked and adjusted everything correctly: gap between knife arm and bill hook, disc timing, etc.
The missed knots seem to be either right or left. Sometimes the knot hangs on the bill hook, sometimes the bill hook seems to be wrapped with twine (I use 9000 poly twine).
I am now wondering if the spring tension of the twine holder is excessive??? The twine seems to be jammed in the disc when I look at it right now (not sure that is typical though).
No hay to test any further...managed to get the hay in last night before it rained. I would have to use loose, dried hay.
