New Holland 270 Baler Problem

I need help with my 270 New Holland square baler. The tines keep jumping over the rail so they're running along side it instead of between the tines. What would cause that? It's too much pressure and breaks the main chain.
 
Mine is a model 65 so has a different feeder arrangement but the concept is the same on all balers. Empty the baler of all hay. Then have someone roll it over slowly by hand while
you watch wat's going on. You should be able to see when it gets to a point where the tines can get out of track. You should then be able to see what's worn, bent or broke that lets
them get out. WARNING!!! keep your fingers out of harms way.
 
That's such a touchy area. Have someone
turn the baler over by hand and watch the
fork travel. Last summer that guide pipe
was bent on the 67 I work with so I
straightened it and when I kicked the baler
in gear I broke a tooth right away when it
hit the pipe. So I bent the pipe back to
being bent the was other originally was and
all was fine. For some reason the forks
don't travel perfectly straight from front
to back. Now the way it is adjusted, a fork
darned near rubs the pipe on the front
side when the forks are back and the other
fork darned near rubs the back side of the
guide when the forks are forward. I figure
it's an old worn machine and it needs to be
adjusted accordingly.
 

Like Belgian said you need to turn it by hand in order to be able to study exactly what is going wrong. In order to turn it by hand you need to cut the strings of the bales in the chamber and pull enough out so that the plunger is not pressing any hay.
 
I had exactly the same problem with my 270 Baler last summer. There was interference between the tines and the bracket that holds the pipe.
It would occasionally catch , lock up , and break the chain. Apparently it had been doing this for a long time before I bought the Baler because
the chain had been patched in eight or nine places. I did a lot of research on the problem in the archives of this forum. A former poster ?Steve
from new Holland ??suggested taking the pipe completely out of the Baler. His fix was rather controversial. But I found no reason why the tines
should be hitting the pipe , the chain was tight , and the times were aligned properly , and the carriage was moving freely in the tracks.
So I took the drastic step up pulling the pipe completely out of the Baler. Since then I?ve Baler several hundred bales and the Baler seems to be
functioning fine. The main purpose of the pipe is keep hay from accumulating high up in the bale chamber. That has not been a problem for me
so far. And I also suggest you put a completely new chain on the Baler tension it properly , and re-time the Baler Carefully.
 
Worn out chain lets it flop at high speeds. Ran a 278 for years. don't actually know anything about a 270, so I could be
wrong. By the way, you can replace that chain for a lot less money at one of the bearing places rather than at NH.
