They have Modern Ag at one of the feed stores. Hot dipped galvanized deck and a good sized gear box looks good to me as my mower deck is rusting out. You can see some of the cutters at this company's web site. Modern Ag Predator Cutters,Grapple Tines and Large Capacity Sprayers
What specialized parts and support are ever really needed for a rotary cutter? There really isn't much unique on any of them that I can think of...what am I missing here?
