Apparatus for leveling the front axle of an agricultural combine includes left and right wheel linkages in the form of four-bar linkages. A connecting rod synchronizes the motion of the four-bar linkages. Hydraulic cylinders are connected between the vehicle frame and the wheel linkages respectively to actuate the linkages such that as one wheel is raise above the axle the other wheel is lowered beneath the axle substantially the same amount as the first wheel is raised thereby maintaining the axle in a generally horizontal disposition.

A marking element is carried by at least one arm which is pivotally mounted to a short boom. The boom, in turn, is pivotally mounted to the outboard end of a tool bar or planter frame. A single hydraulic ram is used to move the marker between a use position in which the arm extends horizontally so the marker engages the ground, and an upright position in which the arm is folded over the tool bar.

An agricultural auger wagon includes a horizontal floor auger and a forward lift auger for delivering grain to a transport vehicle. The lift auger is a folding auger which includes a fixed lower auger section and an upper auger section mounted above the lower auger section in use. The upper auger section is moved by an hydraulic cylinder between the upright delivery position for delivering the contents of the wagon to an adjacent transport vehicle, such as a truck, and a folded transport position. The folding upper auger section has a retractable delivery hood. In the use or delivery position, the upper and lower left auger sections are aligned for delivering product. During the movement of the upper auger section to the delivery position, the delivery hood is moved by linkage to the distal upper end of the upper auger section for maximum height and reach in delivering grain to an adjacent vehicle. To place the lift auger assembly in the transport position, an hydraulic cylinder pivots the upper auger section from the raised, delivery position to a horizontal transport position in which the upper, moveable auger section lies immediately in front of the wagon in a generally horizontal disposition with its axis extending transverse of the direction of travel. A linkage is actuated by the folding action of the upper auger section to move the delivery hood along the upper auger housing to reduce the overall length of the upper auger section in transport while increasing its reach in the delivery position.

An agricultural implement includes an elongated carrier frame with support wheels. One or more tool sections, each having tools mounted to a tool mounting bar, are mounted to the carrier frame. The tool sections are independently raised and lowered between the transport and use positions by hydraulic cylinders. The carrier frame is attached to a tractor by a hitch assembly which includes a control link. With the tractor in the use position, the control link steers the support wheels in the forward direction. In converting the implement for transport, an hydraulic cylinder actuated by the operator from the tractor, uncouples a portion of the hitch assembly and permits the control link to rotate as the tractor is driven to the side of the carrier frame. In thus rotating, the control link actuates the steering mechanism to turn the support wheels so that they all face the side and are aligned with the tractor which transports the implement from the side, parallel to the direction of elongation of the carrier frame. As the tractor turns during transport, the control link and steering mechanism steers to support wheels.

The plow system may carry as many as 10 or 14 individual plow units. All of the units are connected together by a tie rod and may be pivoted in unison relative to a main frame. By pivoting the units, they may be opened or closed to adjust the width of cut between adjacent units over a continuous, wide range. The main articulated frame includes a forward frame section with a main beam inclined relative to the direction of travel of the vehicle, and the rear frame section with a main beam in axial alignment with the main beam of the forward frame section. The forward frame section and rear frame sections are pivotally connected together for rotation about a horizontal axis to permit the system to follow the contour of the ground extending in the direction of travel. The system includes a forward furrow wheel, a rear furrow wheel, and a steerable intermediate support wheel which rides on unplowed ground ahead of the system and is steered as a function of the adjusted position of the plow units.

An agricultural auger wagon includes a horizontal floor auger and a forward lift auger for delivering grain to a transport vehicle. The lift auger is a folding auger which includes a fixed lower auger section and an upper auger section mounted above the lower auger section in use. The upper auger section is moved by an hydraulic cylinder between the upright delivery position for delivering the contents of the wagon to an adjacent transport vehicle, such as a truck, and a folded transport position. The folding upper auger section has a retractable delivery hood. In the use or delivery position, the upper and lower left auger sections are aligned for delivering product. During the movement of the upper auger section to the delivery position, the delivery hood is moved by linkage to the distal upper end of the upper auger section for maximum height and reach in delivering grain to an adjacent vehicle. To place the lift auger assembly in the transport position, an hydraulic cylinder pivots the upper auger section from the raised, delivery position to a horizontal transport position in which the upper, moveable auger section lies immediately in front of the wagon in a generally horizontal disposition with its axis extending transverse of the direction of travel. A linkage is actuated by the folding action of the upper auger section to move the delivery hood along the upper auger housing to reduce the overall length of the upper auger section in transport while increasing its reach in the delivery position.

An agricultural implement, such as a row crop planter, has a main carrier frame drawn by a tractor and including support wheels. Individual row units are mounted on a lift frame. The carrier frame includes a cornered lift post which is mounted for rotation about a vertical axis. A cornered sleeve or collar in the form of a tube is mounted to the lift frame for vertical sliding motion on the lift post. A lift hydraulic cylinder couples the lift frame to the carrier frame for setting the lift frame in (i) a use position wherein the row units are lowered to engage the soil; (ii) an intermediate, raised position wherein the row units are disengaged, for negotiating end turns; or (iii) a fully raised position wherein the lift frame and row units may be rotated from a transverse position to a longitudinal position, to narrow the implement for road travel. A swing hydraulic cylinder is arranged to rotate the lift post when the lift frame is raised to the uppermost position, to torque the lift frame to a longitudinal position for transport.

An agricultural row crop planter is disclosed which includes a frame and a plurality of individual row units mounted to the frame. Some of the row units are mounted in front of the frame to be driven or pushed by it. The remaining units are mounted behind the frame and are pulled by it. Driven and pulled row units are arranged to plant alternate crop rows so the "on center" lateral spacing of row units is much greater than if all units were mounted side-by-side as is conventional. The driven row units are foreshortened and have their frames strengthened to withstand the forces encountered in use, particularly on curves. The arrangement enables the farmer to plant more than one crop with the same planter and without adjusting the spacing of row units. It also permits the manufacturer to provide a wide range of row spacing, including a very narrow one, with the same planter frame and row units while providing greater trash clearance.

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. A second power actuator is adapted to lift the main frame relative to the rear wheel for adjusting plow depth or pulling the system over ground without plowing it.
