New Holland 276 Tine Bar Issue

1130Leo · Jul 16, 2012

My 276 has decided to eat the tine bar, twice on Thursday. The first time, I heard a bang, looked back and saw the back of the chamber getting tore up, then the chain on the PTO side came off along with the cover. When all came to a stop I found the Tine bar in the bale chamber with the plunger tearing the two tines all apart, the chain on the outside broken, the sproket on the main gear box broken, and the shear pin for the Knotters broken. After looking it over, it appears that the gear box that drives the tine bar has some play that is not obvious in the gear box on my parts baler. What else could cause this and what should I be looking for? I don"t want to go thru changing the gear box if that"s not the problem.

Thanks,

Leo

Sounds like gear box drive chain was slack and jumped out of time.Install new roller chains and parts.Gear box is very tough on them,tying system will need to be retimed also. Scott

I was looking closer at it last night, the first time it broke, I can"t say if the drive chain was slack or not, the 2nd time I can say the chain was tight as I had just put it on and followed the guidelines. That said, I should have also looked at the manual for how tight the tine bar chain should be, there was a fair amount of slack on that one, which I now tightened up. The other thing I noticed last night is that the pickup head and the tine bar seem to move fairly hard, I"m thinking that either the clutch for the pickup head needs more lubrication or the pickup head bearings need more lube? I"m new to this baler and obviously have more to learn, other than this, it makes great bales. Any other tips would be greatly appreciated, I"m a rookie at this.
