A hitch assembly having a carrier for attachment to a working vehicle. A pair of lift arms, link member and actuator are pivotally interconnected such that the hitch assembly is lockable in working and folded configurations. In the working configuration, the lift arms are secured to the carrier and the actuator is operable to raise and lower the lift arms. In the folded configuration, the lift arms are pivotable relative to the carrier. Extension of the actuator folds the lift arms relative to the carrier to move the hitch assembly between the working and folded configuration.

A retention assembly to slidably retain a blade to a support bracket of a grader machine. The retention assembly includes a yoke adapted to be coupled to the support bracket, and the yoke includes a base wall, a first sidewall extending directly from the base wall, the first sidewall being configured to face the blade, and a second sidewall extending directly from the base wall, the second sidewall configured to face away from the blade and spaced apart from the first sidewall to define a cavity therebetween, along with the base wall. A retainer extends from at least one of the first sidewall, the second sidewall, and the base, and a bearing arrangement is received within the cavity and adapted to support the blade for sliding movement of the blade relative to the bearing arrangement. The retainer engages the bearing arrangement and retains the bearing arrangement within the cavity.

A boom center section for an agricultural machine includes a bulkhead having a first end and a second end, at least one bulkhead opening located adjacent at least one of the first and the second ends of the bulkhead, and at least one connection assembly disposed within the at least one bulkhead opening. Each bulkhead opening is formed through a first wall of the bulkhead. Each connection assembly includes a plurality of connectors.

A retention assembly, to slidably retain a blade to a support bracket of a grader machine, includes a yoke, a bearing arrangement, and one or more pins. The yoke is adapted to be coupled to the support bracket, and includes a first sidewall, a second sidewall, and a cavity defined therebetween. The first sidewall defines a first thickness and one or more first bores. The second sidewall defines a second thickness and one or more second bores. The second bores are correspondingly co-axial to the first bores. The bearing arrangement is received within the cavity and is adapted to support the blade for a sliding movement of the blade relative to the bearing arrangement. Further, the pins extend correspondingly through at least one of the first bores or the second bores, and into the cavity to engage and retain the bearing arrangement within the cavity.

A work vehicle includes a first ground-engaging implement and a second ground-engaging implement connected to a chassis. The first ground-engaging implement moves within a first movement envelope with respect to the chassis, and the second ground-engaging implement moves within a second movement envelope with respect to the chassis. A lift arm is connected to the chassis and positioned between the first and second ground-engaging implements. The lift arm moves along a range of movement between a raised position and a lowered position. The lift arm is entirely positioned outside both of the first movement envelope and the second movement envelope within the entire range of movement between the raised position and the lowered position, such that the lift arm is permitted to move along the entire range of movement between the raised position and the lowered position without abutting the first movement envelope or the second movement envelope.

A control system for an agricultural work vehicle is provided, the control system includes at least one controller, at least one control input device configured to send control signals to the at least one controller, and a header positioning assembly configured to interchangeably couple a plurality of headers to a chassis of a traction unit. The header positioning assembly is moveable between a plurality of orientations with each of the plurality of orientations providing a unique mechanical advantage. The at least one controller is configured to output a plurality of control commands corresponding to the control signals generated by the at least one control input device, and the control commands are configured to effect movement of the header positioning assembly between the plurality of orientations. An agricultural work vehicle is provided and includes the control system.

A mounting system for mounting a farm implement to a tractor having a bracket attached to the front of the tractor, the bracket having a forwardly extending portion and an upwardly extending protrusion. The mounting system comprises a farm implement attachment member comprising one or more arms with a connection mechanism adapted to connect to a farm implement; a height adjusting mechanism adapted to adjust the height of the farm implement when connected to the one or more arms of the farm implement attachment member; and a tractor connection mechanism adapted to latch onto a bracket on the front of a tractor, wherein the tractor connection mechanism comprises a connection plate, a top hook extending rearwardly from the connection plate, and a bracket engagement member extending rearwardly from the connection plate, wherein the top hook is configured to hook onto the upwardly extending protrusion of the bracket and wherein the bracket engagement member is configured to engage a bottom of the bracket.

A locking mechanism for an agricultural header includes a rod configured to extend laterally along the agricultural header and a cam coupled to the rod and configured to engage a respective arm of the agricultural header. The arm is configured to support a cutter bar assembly of the agricultural header, and the arm is configured to rotate relative to a frame of the agricultural header. The rod is configured to rotate in a first direction to a first orientation to engage the cam with the arm to block rotation of the arm relative to the frame, and the rod is configured to rotate in a second direction, opposite the first direction, to a second orientation to disengage the cam from the arm to enable rotation of the arm relative to the frame.

A support system for an agricultural header includes a first actuator configured to couple to a frame of the agricultural header and to a first element of the agricultural header. The support system also includes a second actuator configured to couple to the frame of the agricultural header and to a second element of the agricultural header. Furthermore, the support system includes a third actuator configured to couple to the frame of the agricultural header and to the second element of the agricultural header. The support system also includes a fluid supply system configured to provide pressurized fluid to the first actuator and to the second actuator. The third actuator is fluidly isolated from the fluid supply system, the first actuator, and the second actuator.

A device for hitching and lifting an agricultural tool, including a frame fastened to the agricultural machine, a first arm articulated on the frame with a first tool hitch at one end, at least one first jack connected at one end to the frame and at the other to the arm, an extent of the travel of the jack allowing the end of the arm for bearing the hitch to successively pass through a first minimum low position, a second maximum high position, and a third retracted position, where a detection unit that detects a position of the end of the arm can deactivate the supply of the jack when the end reaches the second position, and a bypass controller can bypass the controller of the detection unit to reactivate the supply of the jack.
