Need advice New Holland 275 square baler

[Pusto]

I am still struggling with my baler, having knotter problems. My left side billhook wants to hold onto the knots, resulting in that side twine trailing along and the bale scattered. I tried loosening the twine holder tension spring, which resulted in it not holding the twine. I guess I loosened it too much. Also, the bill hook has some rust pits on it, causing what could be viewed as the "rough spots" described in the operator's manual.
The manual says that one possible cause of "hanging knots could be the billhook cam adjustment is too tight. What about this. How does one get the thing out to work on it?
Almost done...How do you know where to adjust the bail density screws as a beginning position? Many thanks for any help.

knot issues can be a real nusiance, and have even caused some good machines to get scrapped. Best bet is find a mechanic that knows what he or she is doing. Luckilly I have a retired farmer/Mechanic at my disposal. I realize it comes at a cost but most dealerships have good mechanics.

Just my 2 cents

You would be better off asking under the New Holland Ag forum or the general ag forum. Lots of people here can help.

I would, but I work on Deere knotters 98% of the time (that will change this year, friend I help now has NH 570). It has just been too long since I have touched a NH knotter, I don't want o tell you wrong.

As far as it hanging up common things to both knotters are the twine tension and the rough spots you are describing. If the knife isn't sharp or set correct that can mess with things and your wiper arm adjustment. If it is like the Deeres you need to have very little clearance between the hook and the wiper plate. Too much and it won't push it off the hook.

This one should be easy. Rust pits on the billhook mean that the wiper arm (which scrapes the completed knot off the billhook) is not making contact with it. The wiper arm needs to be "modeled" so that it actually makes hard contact with the billhook heel. That simply means you need to bend the arm into position. Contact should be firm but not excessive. You can do it in place by making gradual adjustments. I use two Crescent wrenches: one on the wiper arm itself and one on the first wrench at 90 degrees to it. That allows you to twist the arm upwards towards the billhook, in the contact area, without screwing it up in other areas. Run it thru by hand a few times withou twine in the rig until you get it right. Since you have one knotter working OK, you should be seeing a difference between the contact pressures before you begin this adjustment. A manual would tell you how much actual pull thru pressure is required. Mine says that a force of 5 to 10 lbs is proper for pulling the wiper arm ledge across the heel of the billhook.

Thank you to everyone who is trying to help me with my old baler. Up until two weeks ago, I was very ignorant when it came to balers, but I am learning quick.I found a post from somewhere that had pictures of how the knotter actually moves, and this is very helpful. I think the rust pits on the billhook are a problem, and I also suspect that one of the twine fingers could be out of whack. The wiper blade is making positive contact with the bill hook, however the more problematic billhook, the left one, seems to have more contact pressure than the other one, which seems to work ok. I am going to turn the baler over by hand, and then check the proper adjustment of the twine fingers, according to the manual, and go from there. A good mechanic is certainly a good bet, and I will consult with him this am. Thanks for all your help.

I turned over the baler by hand, tripping the knotter, and checking the twine fingers as per the instructions in the manual. They were not even close with each other, and the left one appeared to be about half and inch out of adjustment. I adjusted the separation between the twine finger and the needle, one thirty-second of an inch, and then set them as required. I was surprised at how out of adjustment the left twine finger was. I tried to adjust the twine disc, with the one eighth inch off-set on the disc shoulder, but for some reason I could not get it right. The right side twine disc appears to be properly set, but I did notice something that what I think is the twine disc cleaner, was mis-aligned, and was not centered on the twine disc the way the left side one was. I loosened the twine holder tension spring, and managed to work it back into the proper position. I have no idea how it got mis-aligned. I did notice that the billhook wiper blade was connecting with the bilhooks, and were making a clicking sound when they did so. Now, if we get some rain soon, I can make some hay and try this thing out.
