twine problems in McCormick 46 baler

Hello! My neighbor has a small farm, and last year he bought a McCormick model 46 baler to pull behind his tractor. When he got it home he found it didn't work. He is unfamiliar with balers, but a good mechanic; he took it apart and put it back together, and everything works except the twine. The baler makes a fine bale of hay, but the twine won't go around the bale of hay - it breaks off, on both sides of the bale, around two feet long, and gets all tangled up in the knotters and knives.

He has a manual, but says it doesn't give him enough detail about this. He wants to know, what causes this problem, and how can he fix it??

Also, I looked up what I could find on this subject a few days ago on this site, and one person said if you were having trouble with your twine you should check the hay dog springs. My neighbor doesn't know which these are - could you explain their position in the baler?

Thank you very much for having this forum - we can't find anyone around here who knows anything about these balers.

sounds like twine is binding up in eye guides" newer guides are made of porcelium, where the older ones metal, that rust and get groves worn into them. Twine sounds like it is breaking on breast fingers, If there is knots in the ends of twine, then the floor deck knot slide off slot is worn Sharp and needs to be grd down flat across to drag the knot off the billhook. polishing the billhook helps to.

 more info on what the baler does! in reply to Jan, 01-31-2005 19:36:09  
Gosh, thanks guys! I copied out your replies earlier today and took them out to Jimmy, and tried to get all the answers and info I could.

He bought new twine, IH 9000 ft, not plastic. He isn't sure if it is properly routed - he didn't do it himself, but got another local farmer to do it who has a baler of his own (not the same kind though, I think). The thing on the back of the baler that shows how to string the twine is mostly worn off, and his manual is mostly worn off too.

There is no loop or knot in the twine when it breaks off - it is not cut sharply, but looks broken or rough. Both pieces of twine break off in the same way, same length, about two ft long.

He did spin it by hand, and watch, and it runs fine that way.

He said that what happened was, he made two bales of hay. By the time he stopped, there was so much twine all wound around and tangled around the knotters and knives that it took him 45 minutes to get it off. But up to the knotters and knives the twine was running perfectly straight.

Whew. Okay, hope that helps. I sure wish Jimmy could just sit down with you all to have a long talk. I have never even seen a knotter or knife, so am talking blind here. I greatly appreciate your patience.

Thank you all again for your help, Jan

Hello I used one of these balers in the 60's and have one now to restore. I recall when this baler came out International had their twine and our baler wouldn't use just any kind of twine. So a bundle of International twine was 9000 feet so now I try to find twine like IH twine I figure the size has to do with the knotters working.

I agree with Paul's post below about slowly cycling the machine. Breaking of the twine as you describe seems to suggest a twine tension problem. I would check the tension adjustment inside the twine box and to make sure that the twine is properly routed thru the eyehole guides on its way thru the needles. If it was breaking up by the knotters, I would say billhook tension or dull or misaligned twine knives.

There is a tension adjustment for the twine beside the twine storage. Make sure it is not too tight.

Jan, this is just a shot in the dark, but does he have new twine in the baler?. You would be amazed at how twine can break down if it was rained on or has sat in the damp for a period of time. We were having trouble with an MF10 and discovered that the twine had some dark stains on it every few feet..put two new bols of twine in and have baled on without any problem. As has been mentioned, I would slack off the tension and try a few bales. I have never owned an I-H baler but I have always heard that the #46 in running condition was a great baler and would put up a lot of hay in a day...Mike in Exeter Ontario

It has been sitting for 25 years we got it going but the one side is making a loop with the knot that it should not. We have taken it apart JB welded part of it to make it feed but it still keeps cutting the string. Is there a way to replace the knotters? We have sharpened the knives baled about 100 bales but are wanting to do more just cannot figure out what to do? Can I replace the knotters and where would I find some? Need answers or suggestions. His Dad thought he would never see it bale again and was tickled to death to see it bale He is 80 years old and would just like to see him get a kick out of it besides needing square bales. Thanks Dawn

Had a McCormick 46 baler 25 year ago, remember some but not all, it sounds to me as if the twine is not threaded corectly that is causing the problem, these balers are designed a little different than most that in most it will automaticly pull the twine off the bill hook without the pressure of a bale being fed thru but on this baler the bale being pushed thru is what pulles the twine off the bill hook but if it is threaded properly if it doesent tie it will have a full length string and they will not work with plastic twine, also if the metal slides built into the plunger are wore then it will not tie but then you still have the full length string so I still think that it is not properly threaded, a dull knife will cause not to tie but then the string will be 2 bale long

Here goes with what little I know. I have owned a couple of New Holland balers and one IHC. I guess that my balers are a little different than other balers in that they do not make a groove for the twine at least I am pretty sure they don"t. What they are is a spring loaded pieces that are located at the top and bottom of bale chamber. What they do is the spring allows them to push away from the hay as the plunger pushes it into the bale chamber. They then drop down into the chamber holding the compressed hay until the next cycle of the plunger comes around pushing in more hay. I do not understand how they make a groove for the twine because on mine they are not near the twine. Ninety per cent of twine breaking problems that I have been around where having the bale tension too tight. Having the twine tension too tight is a possibility but I tend to rule that out because you mentioned twine tangling in the knotters which leads me to lean toward too tight of bale tension wich will have a tendency to cause the knot not to be swept off the knotters. If the knotter is out of adjustment can cause this problem also. The manual should cover how to check to see if thy are set right. On the IHC balers I have been around if you do not keep them up to rated PTO speed they have a tendency to do as you have described. I do not know if this was just these balers or all of them but it is something to think about.

I aslo know nothing about that brand.

Did he route the twine properly? Sounds like the twine is busting off before it even gets to tying a knot from your description.

Have you tripped the knotter, and spun the flywheel by hand to watch what it actually does?

If it is trying to tie a knot & it got that far, is there a loop on either end of the attempt, is the twine ragged or cut sharp?

Sisal or plastic, by the way?

The dogs are little springs on my NH that make a groove for the twine to 'flow' in - makes a bit of a groove in the bale.

I've never worked on that make but knotters all pretty well work the same.

Did he check to see if the knotters are adjusted properly as per manual? Does it actually tie a knot? Does the knive arm wipe the knot off the bill hook? Both sides don't tie??

Pretty hard to diagnose with out a lot more info as there is many things that can cause what you mentioned.

Older IH balers do not have a twine wipper arm. I would check for bad twine as stated in other posts , then we need more info-does it tie a knot in one end of the twine, etc etc.In my IH model 47 baler's manual there is a very good trouble shooting guide. It could be your tine knives are eithrt out of adjustment or dull and the knots are pulling apart.
