This is my first year using a 14t, so far it has done a good job on straw. The only problem with it is about every 10-20 bales it only ties a single twine knot instead of a double twine knot on the left side on the bale (looking from the rear of baler), the other side ties perfect every time. The single knot pulls apart when it goes through the bale case, I'm using regular twine, not plastic, and I adjusted the fingers and every thing else that was in the manual like it said, including twine tension(used fish scale), anyone got any ideas on something I missed? I got to bale hay this week and I was hoping to figure this out. thanks
