Abstract: A mounting for a side wing plough includes a mounting having two relatively movable sectorially formed elements, one of which being fixed to the plough and the other being connected to a lifting means for the leading end of the plough. The two elements register with one another and are guided thereby, the interengagement of the elements constituting the connection enabling movement of the plough and also permitting limited compensatory shifting of the plough upon encountering an immovable obstacle. The mounting could further include a tilt mechanism of limited stroke affording the capability of the plough to tilt toward the vehicle to accommodate unpredictable movement of the plough upon impacting an immovable obstacle.

Abstract: Closely spaced cultivating tools are mounted along a tool bar and each tool may be locked in a raised position relative to the ground or may be lowered into floating engagement with the ground during use of the implement. A small tool bar is mounted parallel to a larger tool bar and the cultivating tools are slidably clamped on the small tool bar. Improved mounting structure allows each cultivating tool to be mounted on the small tool bar without having to slide each cultivating tool onto or off of the tool bar from the ends of the tool bar and without having to disassemble the mounting structure. The tool bar assembly includes row indicia for indicating where the tools are to be located along the tool bar and which tools should engage the ground and which tools should be raised away from the ground for various cultivating operations on row crops. A tool angling mechanism allows selective adjustment of the angle to the line of draft of each tool without the use of wrenches or other hand tools.

Abstract: A plurality of plow units are mounted to a main frame of a plow system for rotation about their vertical axes. The plow units are spaced at equal lateral increments and at uniformly increased distances from a pivot connection between the main frame and a traction vehicle. The plow units are ganged together by means of a guide beam; and a power actuator controls the motion of the guide beam in rotating the plow units so that their cut lines take a predetermined position relative to the main frame. As the plow system is then used to plow ground, the main frame swings about its pivot connection to the tractor until the plow units line up with the direction of travel of the tractor, thereby adjusting the spacing between plow units automatically. The rear plow unit is mounted to a tail section which is pivotally mounted to the main frame and includes a rear wheel for supporting the distal end of the main frame and for steering the system as the tractor turns.

Abstract: A control system for circle mounted motor grader blades to enable adjustment of the circle and blade supported thereby about the axis of the circle is disclosed. The system includes a circle holding mechanism for reducing wear between the circle and the mounting structure therefor, which circle holding mechanism also automatically compensates for inaccuracies in operation due to such wear and to the tolerances between the circle and the mounting structure required to facilitate adjustments in the relative positioning thereof. This circle holding mechanism includes a wedge device which forces the circle into a shoe element to hold the circle in fixed relationship with respect to the mounting structure therefor.

Abstract: A field drag particularly adapted for use in conjunction with a post-plowing cultivating implement includes a mounting bar section pivotally secured to the frame of the implement and extending in a rearward direction behind the implement. A plurality of spaced, soil-working teeth are secured to the bar section and extend downwardly therefrom and generally toward one end of the bar section so as to form an acute included angle with respect to the bar section. An adjustable spring tension arrangement pulls the bar section resiliently toward the implement thereby urging the teeth into the soil as the drag is pulled across a seedbed to break up and pulverize clods and smaller chunks of earth into loose soil. In a modified form, the teeth may be fastened to the bar section to slant selectively toward one end or the other of the bar section.

Abstract: The motor grader drawbar assembly has a blade mounted on a circle gear and a drive unit operatively connected to the circle gear to selectively rotate it and the blade. A plurality of radially mounted pistons operate against an upright wall of the circle gear to provide a brake and/or locking mechanism. The pistons, and their accompanying cylinders, are mounted in members which also underlie and support the circle gear. Thus, the vertical position of the circle gear is not affected by the braking operation. A hydraulic circuit is provided to alternately operate the drive unit and the braking operation.
