Abstract: This invention is a simple, safe, and inexpensive beam structure for tractor forward mounting of a blade (24). A pivot plate (11) is mounted at the tractor lower mid-section. Parallel beams (12) are positioned through the pivot plate (11) and extend beyond the tractor front and rear.

Abstract: An apparatus, for stabilizing a plowing implement mounted on a motor vehicle, comprising a rigid stabilizer member having first and second opposed ends. One end of the stabilizer member supports an attachment device for attaching the stabilizer member to a plowing frame secured to a motor vehicle. The attachment device allows pivoting motion of the stabilizer member relative to the plowing frame. The second end of the stabilizer member has an abutment surface for abutting against a pivotable portion of the plowing implement when the plowing implement is raised into travel position. The stabilizer member is pivotable into an inoperative position where complete freedom of movement of the plow is achieved and an operative position by a control mechanism. When the stabilizer member is in its operative position, the abutment surface abuts against a pivotable portion of the plowing implement to minimize undesired bouncing of the plowing implement while the vehicle is traveling on a roadway.

Abstract: A chain is connected at its distal end to the pin at the rod end of a cylinder on an implement lift and depth control assembly. An intermediate portion of the chain is trained around a gear which rotates about the axis of the pin connecting the base end of the cylinder to the implement frame. An adjustable length, spring-biased rod is connected to the proximal end of the chain to maintain tension in the chain and operate a single point depth control valve to establish a highly accurate and repeatable depth setting which is dependent directly on cylinder rod extension and therefore less susceptible to looseness in the implement lift system.
