Solved our knotter mystery (s) on our NH276

So many little things...

Some chaff had gummed up under the hay dogs. I realized this by ear. They weren't clicking with every plunger stroke. And one of the springs was almost worn through on the end, where you can't see.

Also...worm gear on the new twine discs had a hairline crack. Maybe I tightened it onto the taper too hard. I noticed this, because my new twine discs were floating in and out of time.

Big one though... The roller on the twine finger activation bar was frozen. And the bar needed a little shimming to the right side. The effect uf this was that the twine finger cam was sometimes hitting the bar, not the wheel, and when it did hit the wheel...no rolling. So it was worn. While I helped unload wagons, my daughter's boyfriend stacked about ten beads of weld on the cam and ground it to a profile to match the cam on our spare baler (not functioning yet...)

Other parts I had new or scavenged from the spare baler or the knotters in the garage.

Went to the field and reliably made tight bales with good knots.

Finally!

(quoted from post at 10:06:30 10/24/22) Yes, on knotters it's the little things that count.

Yup. And reliable knotters are the difference between loading a wagon in twenty minutes or an hour and a half. I don't have metrics for it, but baling with bad knotters puts maybe two to three times the wear per bale on other parts of the baler and the operator.

Climbing in the wagon, pitching out broken bales... turning the rig around to re-bale.

Either you leave the whole machine running while you're driving around picking up the messes, or you start and stop the PTO... either way... Everything runs longer, the PTO starts from a dead stop more often... it just snowballs to a time wasting, money wasting and soul-draining endeavor.

Funny thing is, even though I'm supposed to be the "old-wise" guy on the farm... I find that involving younger members of the crew in troubleshooting, and letting them drive the baler, while I stack wagons or ride along on the twine box watching and adjusting tension... is more productive than sitting out in the field lording over the baler. I can't see what's going on, if I'm sitting in the tractor seat, just trying to send bales back to the barn as fast as I can for someone else to unload.
