  • Publication number: 20090114406
    Abstract: A harrow frame may be operable to permit pivoting of its ground working tool support arms between a first relative angle and a second relative angle. Pivoting may be achieved through a drive system and a lock controllable remotely such that the tool support arms can be pivoted about their fulcrums “on-the-fly” while the harrow frame is being moved along a ground surface. In addition or alternately, a harrow frame may also be folded to have a width less than 8.5 feet to facilitate transport.

  • Patent number: 4489791
    Abstract: This invention is a simple, relatively inexpensive tool bar structure featuring a rigid rectangular frame work pivotally mounted on the rear axle of a tractor. When the tractor is equipped with a hydraulic lift system, and said hydraulic lift system is flexibly linked with the invention, a tilting rigid tool bar structure is provided thereby. This tool bar structure will allow many implements that are adapted to commonly used 2 and 3 point hydraulic lift systems to be used on any and all sides of the invention if so desired.An unusually heavy implement's weight may be counter balanced over the pivotal mounting of invention by counter weights or with other elements of their construction that can be placed forwardly to relieve the overload of tractor's hydraulic lift system. The lateral stability of the tool bar is also greatly improved with the anchoring of tool bar structure on the tractor's rear axle shaft.
