NH 688 Baler problems

[tractorguy88]

I just bought a 688 baler and seem to have nothing but bad luck with it. My main problem is with the twine system. It is an auto wrap and when a bale is twineing, sometimes the twine arms will trip and go back to the begininng twine position. This will happen of and on and it seems that it will do this a few times in a row and then stop and work perfect for awhile, then will start doing this again. We talked to a dealer and he said there is a set screw on top of the arms to adjust, and i have adjusted them a little today, but they still seem to do it. Every one else we talked to who has a 688 said they never seem to have this problem and they claim that they are some of the best balers made, but this problem is frustating and is costing me time and money in the field. I was wondering if someone had this problem before

All you need is some WD40. I don't know what is is called but the thing that lets the arms trip and stops them has some rust in it. trip your arms and go around on the right side and spray it with WD 40 and work it back and forth. I'm sure that is clear as mud but it will work. I have a 664 and it will do the same thing.

I'm not sure if the twine arms are the same but I have a BR 780 baler that I think is similar. Sometimes the twine arms do not go back into the proper position. When they are up in the middle take one arm in each hand and slam them together to be sure they are caught in the correct position. Be sure they are greased well. I don't think the adjustment bolt makes any difference. I had a mechanic show me that and they have worked just fine since he made his "adjustment".

I agree with the WD40 only add an air hose.On the right side of the baler, if it moves, hose it and then soak it. Do that regular and if it stays parked inside during the winter it will come out of it and you might only have to do it once a year when you first start.

Yep keep that plate greased that goes around controlling the twine arms and lots of wd-40.
