I am hoping someone could post pictures of the twine cutter bar at the knife where it hits the angle iron. And also describe how it works as far as which way the knife moves from home position to wrap and back home. Thanks!

The knife comes down to the angle iron....pinching the twine and cutting it off. If it is set correctly there will be a bit of twine pinched between the iron and knife, so that while baling the next bale the twine doesnt swing around and get caught in the new bale while baling it (Can lose a lot of twine that way, if you dont notice it). There should be a L shaped iron that guides the twine into the knife/angle iron position to cut. If it is missing it will not be in position to cut. The L shape piece is on a groove so you can set it in the proper position. If you dont have the L shape piece....simply bend a bolt and mount it in the groove with two nuts. You should have a U shaped bracket about 2 feet above the knife that the twine arm rides in while not tying. When you hit the hydraulics to tie the bale, the arm pulls the U down (Upside down) and opens the knife up from the angle iron. After you are done tying and you move the twine arm back into place the U will flip up again, closing the knife on the angle iron and cutting the twine. This is if you have the manual hydraulic tie option? I have a 847 NH baler, which is basically the same baler...just a bit newer. Wayne

This is what I have been needing!! The problem I'm having is, when I have the knife on top of the angle (yes, mine is a manual hydraulic)and the string tube Is in the U that is in the most upright position when I hit the hydraulics the knife raises moving away from the angle. I have the adjustable rod that runs from the U bracket to the knife bar hooked at what is the front of the knife bar, the rod has a good bow to it. Hopefully by straighting the rod it will cause it to push the opposite direction. Right now the only way I have been able to make the knife hit the angle is to have it under the angle where it will come UP to cut. Your information has helped greatly and I appreciate it. If you have any other suggestions I'm willing to listen. Thanks again!!

If its like the 847 the arm that holds the knife just flips back and then latches shut to cut the twine when the arm comes back to the 'home' position.The keys to working right are a good sharp knife and
have the little L shaped arm that guides the twine adjusted in the correct position.Is it not cutting the string now or are you getting the initial adjustment set up? Also the latching and unlatching assembly needs to be well oil/greased and working freely.

I'm not sure if the knife is supposed to sit (in home position) above the angle iron or below. The little L hook is broken off and I don't know what position and where it is supposed to be. I'm basically taking parts and trying to figure out where they go and how they work. I certainly appreciate your help in anyway you can.

You need to get an owners and parts manual,if the arm is gone it won't cut the twine.

I have an owners manual but it doesn't show a good picture of the knife nor does it tell if it moves up to make contact with angle iron to cut or if sits above the angle and moves down to cut, I guess that is the main question I need to figure out. I do have the arm and everything I need pasts wise.

The rod goes from one side of the baler to the other that holds the knife assembly and its all above the angle it goes down against to cut the twine.Hard to explain exactly if there is another NH chain baler around you area you need to look at it to get a good idea how it works.Or maybe it sounds like someone has rigged up the cutter assembly I've seen all sorts of things done to those and most don't work very well.

There are a few different NH balers close to home, none are 846 but it's probably worth taking a look to see if any work similar to the 846. Thanks for all your help and info.
