New Holland 269 missing knots

[Round3Ranch]

I have a New Holland 269 square baler. It is a beautiful baler and makes wonderful bales. Ever 75 bales or so it will miss one knot then the next and then it will correct itself and be fine for another 75 or so. It is last years twine in the box but I m too cheap to replace as they where brand new late last year. It s only on the rh knotter only and it s only after about 75 bales almost can can count 75 knotter cycles and be ready to watch for it. I have looked over the knotter assembly and the bill hook is smooth and no burrs, the twine discs seemed timed, the baler is in time, the rollers on the back side seemed ok I haven t seen any flat spot. The knot is not hanging up on the bill hook it comes off just fine just doesn t hold the knot and comes loose from what I see.

What does the failed knot look like?

If it is always the rh knotter and never the left you have a big advantage. Empty the baler of hay and twine. Then trip the knotter and start going through the cycle by hand. Turn the flywheel a quarter turn
at a time and go back and see that both are the same, and I mean exactly the same, at the same time and place.

My NH 271 misses a few knots on the right hand knotter. I found that if I keep the RPM up it solves the problem. I am currently waiting for a new tractormeter therefore only can guess the tractor's RPM but it is somewhere around the mark that produces 540 PTO RPM.

I grew up stooking behind a
269. It was not a good baler.
Dad traded it in on 2 older
#12 Massey Ferguson balers and
later I bought a 124 MF and
never looked back

from what I can see if I m not too late is it looks like one end held a knot but the other slipped through. Can see the two strings look like they where in a knot but it looks like it just didn t hold. Do you think billhook tension?

To diagnose your problem it is necessary to know whether the one end that has the knot is in the end over the top of the bale, or in the end that has just come up a the end of the bale. It is almost always in the end over the top of the bale. This is because the twine being brought up through the chamber by the needles is not being brought to the twine disc. with NH and JD balers this is usually the tucker fingers. To find this problem you need, as flying Belgian posted, to get most of the hay out, and roll it SLOWLY by hand and watch the tucker fingers cycle and compare side to side. HOWEVER, there is another possibility that is not as likely, but is a whole lot easier to ID and fix. This is the hay dogs. If they get stuck it is very hard for the needles to get the twine up to where the tucker fingers can grab it. Just lubricate them if they are stuck.
YOU NEED a MANUAL! every few years or thousands of bales go through the knotter service and adjust in order start to finish.

Is there tension coming out of the twine box? My 67 had a groove wore in the bottom spring loaded piece that was to keep tension on the twine. That would allow the twine to jump out of the back side of the needle when it cycles and cause a missed tie. It would do that for two or three bales then start working again for awhile. I hope that makes sense. I'm not always the most goodest at explaining things.

Wrong showcrop. If there is no knot on
the twine over the top, it is a twine disk
pullout.

If no knot in the needle twine, it can be
tucker fingers, hay dogs, or twine disk
timing.

If it is just 1 every 75, you might consider that making changes to the knotter without being sure what you are fixing...might make it worse,
1 in 50 or even 1 in 10. Knotters can be fickle. If you are only doing a few hundred bales...3 or 4 broken bales is not a crisis...If you are
doing 1000/day....may be worth fixing.

What twine are you using. My 269 would do that with TSC 135 orange twine. Started using 170 and the problem
went away. Seems the 170 wasn't as slick as 135.

Round3,go order an owners manual. About 40 bucks. That book will have a trouble shooting guide with pictures. Then it will tell you how to fix. Read the book,in about 10 minutes you can have the issue
addressed.Adjust it by the book,in the order of the book ,and unless something is broken or just plain worn out,it will tie like a new one.And yes,even us old dogs need to read the book from time to time.That
book will be the cheapest,most usefull thing you will ever buy for your baler.

Roger, we are saying the same thing, LOL.
