Abstract: A tillage machine includes a main frame, a gang rotatably coupled to the main frame, and an arcuately-shaped adjustment rail coupled to the main frame. At least a portion of the adjustment rail is spaced from the main frame. The adjustment rail includes a plurality of apertures each configured to receive a locking structure, and the adjustment rail defines an open space adjacent the main frame.

Abstract: An agricultural planter is provided with hydraulically operated devices to effect the folding and unfolding of the planter support structure between operative and transport configurations. The planter includes a telescopic hitch apparatus that lengthens as the pivoted wing members are folded forwardly to position a transport lock mechanism for engagement with vertically oriented wing latch retainer bars mounted in a latch tower on the draw bar. A hitch latch mechanism is also provided to control the movement of the telescopic draw bar. A caster lock apparatus is also provided to control the castering action of a wheel device positioned near the ends of the wing members. In operation, the laterally extending tool bar is pivoted on a transverse axis to forwardly roll the tool bar toward an intermediate transport position.

Abstract: An agricultural implement, having a tool bar that is pivoted forwardly to initiate the conversion of the implement from a working position toward a transport position, including left and right wing members extending in opposing directions to respective distal ends, is provided with a lift assist mechanism to support the distal ends of the wing members as the tool bar is pivoted forwardly to an intermediate transport position. The lift assist mechanism includes a frame pivotally mounted to each respective wing member, a lift assist wheel providing ground-engaging support for the wing member, and a lift assist actuator that controls the pivoted movement of the lift assist mechanism to maintain the lift assist wheel in supporting contact with the ground until the tool bar has been rotated approximately 60 degrees from the lowered working position toward the raised intermediate transport position.

Abstract: An implement lift system for a machine such as a front mouted mower having a pair of transversely spaced lift arms operable by a single life cylinder. The lift cylinder is transversely adjustable utilizing a special cylinder bracket arrangement and a transverse member extending between bend locations on the lift arms forwardly of the pivotal connections of the lift arms with the vehicle. The transverse member is connected to provide lift to both arms from the single cylinder while permitting independent vertical movement of each of the arms. Compensation for unequal forces acting on the lift arms can be provided by moving the cylinder laterally to achieve even lift and flotation characteristics.
