New Holland 278 Baler.

brucehopf · Jun 21, 2014

Today, I tried to bale some hay, with my 278 New Holland Baler. Right away, I had issues, with one of the knotters. It seemed to tie a Slip Knot, on one bale, and it would miss, the second bale. Then just like that, it would tie, for about 8, or 10 bales, or so, then back, to tying Slip Knots, and miss the next bale, slip tie the next, and mid the next one, right after and would tie, a few more bales, again.
I swapped out balls, to a new one, figured that was the problem, tied a few more bales, and right back to square one, with the slip knots.
What am I missing? I greased everything, before, I started baling. Your help, and advice, will be Greatly appreciated. Thanks in advance. Bruce.

I spray silicone lube on the discs that hold the twine and on the
fingers, it seems to help sometimes when the baler mis-ties. May
be worth a try for you.

Bruce,

I have a NH 273 baler. I don't know if the knotter assembly is the same as the one on your 278, but I would guess that it might be.

There are way too many moving parts, most of which are interdependent, on the knotter to begin to guess why your knotter isn't working consistently.

The only way for you to solve the problem is to get out your Operator's Manual, or your Maintenance Manual, and go through the knotter adjustments on a systematic basis.

I wish that I could give you a simple answer to your problem, but there isn't one. There's a great youtube video that was put out by New Holland many years ago explaining and showing how a knotter works. If you haven't viewed it, might do so.

Good luck,

Where you need to look for the problem is dependent on which end of the twine has the loop. Some of the common problems are stuck hay dog or broken hay dog spring, bent twine finger arm bent and loose twine tension where the twine comes out of the twine box.

As said in other replies there are many factors that cause problems. On my Ford 632 baler doing the same thing, the pin that holds the moving finger in had backed out slightly catching the twine on the way around. In my case it probably missed more than stayed tied once you pulled on the string. Course, could not see it and when found it- did not think a little bit of pin stickout would matter. Good luck and yes do check whatever manuals you have.

sorry for the long delay. I took everyone's advice, and I really studied, the needles, on the baler. What I found, was some rust, and a burr, on the side, of the needle, so I took some Emery Cloth, and removed the rust, and the burr spot. After that, no more issues, with miss tying. Thanks again, for the help, I greatly appreciated it. Bruce.
