New Holland 273 Baler Pin Shear

I have a New Holland 273 Baler. Bales about 275 bales today and started shearing pins. It sheared on fly wheel then on knotter. Noticed after shearing about 4 pins it shears when needles are in up position to tie a bale. Any suggestions?
 

I tighten the brake up about one turn and it tied one bale and sheared again. I also will add that I checked timing and the timing is perfect.
 
Joey,

I'm not trying to be a "smart-alec", I just know about a mistake that I made some time ago. The bolt that compresses the spring that controls the pressure on the knotter brake is an honest-to-goodness bolt, not a stud. To add compression to the spring requires that you put a wrench on the head of bolt and turn the self-locking nut that contacts the compression spring. A long time ago, I didn't realize that it was a bolt. I tried to increase the tension on the brake pads simply by turning the nut. It didn't do any good.

But then again, you probably already know that.

Good luck with your problem determination.

I've got a nh 275 baler and have sheared flywheel shear bolts usually cause I am going to fast in thick hay, dull knife.I have never in the 8 years that I've used this baler broke a knotter shear bolt.There is a video you tube by newholland that shows it in slow motion and it give you a good ideal what to look for,but you need to empty out the baler. Trip the knotter and roll the flywheel over by hand and watch the needle as it enters with the string making sure that it doesn't hit anything and doesn't bind up. Good luck
 

We gave up borrowed neighbors baler and it constantly broke bales. So we gave up and rolling the last 6 winrows. Going to replace the brake and try again next cut. I don't know that the brake has ever been replaced on ours. Hopefully that works otherwise it's going to New Holland. Thanks for replies though.
 
Check the spring on the knotter trip dog. I think that is the right name for it. If it is missing/broken, the knotter can trip randomly.
A $5.00 spring.

Some how tghe needles are falling into the chamber.The needle brake is the first thing to check.Your plunger stop is doing its
job, Check it out.Make sure it is in cordination with the needles. Do you have a book? if not order one NOW. before you really
Firetruck something up. At about 40 bucks,the cheapest and best thing you will ever for your baler.
 
You say it shears in the up position? Check the needle linkage to make sure it's not in a bind on the return home. It doesn't take much resistance to shear both bolts. Once I sat on the twine box to see if I could see a problem with the knotters. When the needles tripped the linkage hit my knee and BAM. Both bolts sheared and I limped for a couple of days .That was not one of my brighter moments.

And no there wasn't a guard on it.

Good Luck.
 
My cousin was watching a baler tie seen a
piece of twine and went to yank it out. 5
hours of surgery broke all the bones in his
hand but one and almost lost his hand. I
was the lucky one holding his hand till he
got to the hospital. I still can't be
around some one that is working on a baler
while it runs.
 
First thing to check is the "Needle Latch" often called a plunger stop. If it is even slightly out of adjustment it can
vibrate into the chamber and shear the bolt. Mine was happening randomly. So look into the crank area after it shears a
bolt to see if the latch toe is out (blocking the travel of the crank arm). Then grease it, lube it and adjust it
according to the manual, which on my 276 is none too easy to understand (bad photo).
