New Holland 68 square baler

[farmerofva]

So I went to an auction looking for a square baler to bale about 100 bales a year I have 0 experience with a square baler I usually only do round but the waste from goats I want to make some squares. I bought it dirt cheap at an auction and knew it would need some tinkering. The chain was broken on the main drive system so I fixed it tried to cycle it by hand it wouldn't move so figured maybe been sitting a while hooked to a tractor chain snapped I tinkered further the gear box on top that I guess runs the fingers that put hay in the chamber will not move I have tapped on that bar and tried to get it to turn but something must be broken in that gear box. Has anyone ever had something mess up in that gear box and it wouldn't spin? I appreciate any suggestions or anything you can think of would be the cause.

That's probably why it was in the auction.

I would look for a gearbox on a unit that is being parted out. Maybe even buy another baler for parts. You'll probably need them.

Or, you could rebuild the box. NH has pretty good support for their stuff.

I found its not the gearbox it is a bolt someone put through the chain that the hay tines that pack are attached to I used a pin so it wouldn't get caught so I cycled it after timing it with drive chain spun everything moved well so hooked to tractor then bam broke a time and chain pin I just put in so I decided to try to see what happens when I trip needles bam broke the shear pin soon as it passes the knottera that happened twice not sure what the problem is or what to look for

What you need to look for is an operators manual.

I have one but doesn't cover my issues.

It is critical that that chain is timed (just like a timing chain on an engine). That timing affects when the "rake" pulls the hay into the chamber, and when the needle threads the twine for the bale. That is very reliable baler.

There are manuals on ebay

I have one but doesn't cover my issues.

Every genuine New Holland Square baler operator manual has detailed timing information. Pay particular attention to the needle latch adjustment. Yours must be ok or you would have broken your needles by now. That is an experience you do not want to have.

Thanks I'll look at the needle latch adjustment

The video doesn't show it, but there is also timing on the "rake" that feeds the plunger. If your manual is not explicit about this, buy a better manual on ebay.
