摘要： An assembly for facilitating steering of an agricultural implement linkable to a work vehicle is disclosed. The assembly comprises at least a first ground-engaging wheel to engage a ground surface below a frame of the agricultural implement to support the frame above the ground surface. The assembly further comprises a positioning system for receiving a positioning signal from a positioning source. The positioning system determines a current position of the agricultural implement from at least the positioning signal, and the positioning system generates a control signal derived from the current position of the agricultural implement. The assembly further comprises a steering cylinder connected to the first ground-engaging wheel. The steering cylinder operatively connects to the positioning system to steer the first ground-engaging wheel based on the control signal.

摘要： A method of and system for moving an agricultural implement between a folded inoperative system for transport and an extended, field position is provided. The method includes the steps of providing an agricultural implement having a right wing of tools and a left wing of tools each located on opposite sides of a central longitudinal axis of the implement relative to each other; moving one of the right and left wings of tools from an extended position to a folded, inoperative position for transport; and moving the other of the right and left wings of tools from an extended position to a folded, inoperative position for transport after the step of moving one of the right and left wings.

摘要： A steering connection assembly for a vehicle train having at least one implement towed behind a tow vehicle in a direction of travel is provided. The steering connection assembly includes an elongated tow bar interconnecting a first implement towed behind a second implement. A rearward end of the tow bar is includes an elongated opening to receive a steering rod member therethrough. A steering arm interconnects the steering rod member to a caster-type wheel assembly located at a forward of a first towed implement. With a first angle of rotation of the tow bar relative the longitudinal axis of the first implement, the vertical steering rod member slides along the opening of the tow bar such that the steering arm member and attached wheel assembly rotate a second angle of rotation less than the first angle of rotation of the tow bar.
