  • Patent number: 4762181
    Abstract: A pull type minimum tillage implement includes a closed rectangular frame having a forward tool bar, intermediate tool bar and rear tool bar. The ground-working tools travel directly over each previous crop row and include a forward coulter mounted on the forward tool bar followed by a subshank and disk hiller mounted on the intermediate tool bar. A mounted planter may be connected to the rear tool bar while a drawn planter is connected under the rear tool bar to the intermediate tool bar. A pair of depth gauge and support wheel assemblies are provided directly over a pair of rows and include spaced apart frame members extending between the three tool bars with a ground wheel pivot arm positioned therebetween and pivotally connected to a bracket mounted on the front tool bar. A hydraulic cylinder pivots the frame about an axis through the forward end of the implement frame tongue thereby raising the rear end of the implement frame carrying with it the ground-working tools.

  • Patent number: 4099629
    Abstract: An elongated finger-support member may be pivotally connected to the three-point hitch of a tractor or to the bed of a pickup truck. The support finger is T-shaped in cross section and tapers to a point and includes a rearwardly facing hook on the top convex surface which supports the baled hay along its axial center. A cross member is provided at the base of the finger for limiting penetration and supporting the baled hay when the finger is in a vertical position. When the support finger is carried on a truck a frame is bolted to the truck bed and includes a cage extending over the hydraulic power cylinder and the cage functions as a stop for limiting the pivotal movement of the finger and further protects the cylinder from the hay. The machine is positioned between the wheel wells of the truck such that the hay is sandwiched therebetween when being transported.

  • Patent number: 4082192
    Abstract: A hay bale arm is pivotally mounted on a base assembly adapted to be carried on the bed of a pickup truck, the front end of a tractor, or on the three-point hitch of a tractor. The hay bale arm includes spaced apart arm portions having finger portions which move between inwardly extending positions for engaging the axial ends of a round bale and upwardly extending positions when the hay bale arm is being moved over the bale. A fixed stop limits pivotal movement of the fingers in one direction while a movable stop selectively limits pivotal movement in the opposite direction.
