This is a very nice New Holland baler knotter.  It fits many of the older model NH balers.  I have listed many of them.  It also fits the Supers.  I have completely dismantled this knotter.  It has been cleaned, inspected, and painted.  It was properly tuned when it was put back together.  The knife arm is in nice condition with a good roller.  The knife is sharp.  It properly rubs the bill hook.  The bill hook is very nice.  The gears are in very good shape as well.  Why do I completely dismantle them? Because I have a scrap steel tub full of cracked knotters that I thought were good until I media blasted them.  This is not a greasy old knotter that hides damage.  This has been totally reconditioned.  Buy with confidence.
