A mini bull dozer that is a work in progress. It is called The Mity Kat Tractor from about the early 50's. It is believed to be the descendant of the USFS Beetle Trail Tractor. It uses the oliver oc-3 rear end assembly, the Hercules zxb and a Twin Disc MTU clutch in the forward reverse box. This is the first drive after years of sitting out in the woods.
