New Holland 276 Baler knotter problems.

Well I know part of the problem is not having the hay in a windrow. Plus not having square baler twine in it but having round baler twine. But would that stop the bill hooks from grabbing the twine when the twine hook bring it up to the knotters?? The guy is suppose to get the correct twine tomorrow so will go and see if that is all that is wrong but if not any idea as to what maybe wrong
 
Would say that if it was working good with the right twine before you put in the smaller stuff that your problem is with the twine. If it wasn't working good with regular twine then you have other issues. I wouldn't want to do a bunch of adjusting now, just wait until you get the correct twine and give it a try. Don't understand not having the hay in a windrow. How else would you bale it?
 
This guy is one of those who will buy something and if the person says it works fine then he is ok with it but not knowing it the guy is telling the truth or not. Baler look real good but also found lots of old parts laying in the tool box plus bags of shear bolts so who knows what of right or wrong and I get the fun of figuring it out.
As for the hay not in a windrow well he did not have but one sickle bar wide cut of it and did not want to rake it up to test the baler
 
If it has the open finger style bill hooks it will not grab the twine. They have to close tight. Aside from that... if it's not forming any knot then I'd say the tucker fingers are not pushing the bottom strand ahead so the billhook can grab it... and that could also be a result of a bad hay dog spring not allowing the tucker finger to grab the bottom strand..

Any chance that the spring that keeps tension on the twine fingers is missing? Some people forget to put them back on after working on a knotter. If the twine finger is not properly adjusted and working freely the hooks can not grab the twine.

I'm wondering, based on where I buy my twine: Where I buy twine, the square baler twine is sold in 9000 or 7200 foot "bales" with two balls of twine each.

Right next to it is round baler twine sold in lengths of (if I remember correctly) 16000 and 20000 feet. At first glance, the balls of twine looked to be similarly sized.

If someone bought one of those 16000 or 20000 foot balls of twine trying to get a bargain; wouldn't that twine be very, very thin compared to the square baler twine, which has about half the length in a similar sized ball?

Maybe the round baler twine is thin enough that the bill hook, twine discs and such can't grab it with any consistency?

Some of the round baler twine that I've seen is only about as thick as net wrap. I have no idea how that could ever tie a decent knot in a square baler.
 
Yesterdayy when I went an looked at it I made sure the hay dogs where as they should be and also made sure the plunger stop was as it should be. I think it has a problem of the bill hooks not rotating as they should and will check that first thing today
 
You know I did not see any tucker fingers on this thing so maybe that is the problem. Guess before I leave here today I'll look at the NH271 I have and see what every thing looks like so I can compare them
 
I'm sure old knows the difference between the 20000 poly and 7200 or 9000...
The thing with the bill hooks is that a sisal hook maintains a gap of 3/16" or so between the finger and tongue of the hook. A poly hook has a recess in the tongue that allows the finger to close tightly and grip the twine tighter to make the twist. You might get a sisal hook to work with 7200 poly but I strongly doubt it... it's just too small to grab effectively.

Might be broken roll pins in the knotter gears? That's about all I can think of to stop the bill hooks from turning. One more thing to check is the plunger wrist pin... I know you said you checked the hay dogs... but did you visually verify that they seat on each charge when the baler is getting pushed? I've had the wrist pin bushing go to pieces in mine and the plunger is not actually making a full stroke under load... it just didn't travel far enough for the hay dogs to drop... and then it wouldn't tie. It would not cut the string either... but it would place it back in the twine disc on the second missed bale and then tie again until it missed...

Correct twine and it worked just fine as long as I could get the guy to not make a windrow by taking 3 or 4 passes to pile a windrow up which was so much hay it would stall the Ford 4600 I was baling with.
