  • Tool apparatus with tool attached to end of outrigger arm
    Patent number: 4936390
    Abstract: A three-point hitch mounted in-row tiller has a conventional three-point hitch mounted frame member with an outrigger arm pivotally mounted to the frame member in a manner that accommodates pivotal movement of the outrigger in relation to the frame member about two orthogonal axes. Pivotal movement about one of the axes causes tilting of a working tool mounted on the outrigger arm, and pivotal movement about the other axis causes vertical lifting and depth control of the working tool. Various working tool embodiments, including several with flexible teeth, and a mechanical/hydraulic sensor apparatus are also included.
