A hitch device for an implement, suitable for being mounted on an agricultural vehicle, including a chassis transverse to the direction of travel of the hitch, a system for coupling an agricultural implement to the chassis, the coupling system being designed to pivot freely relative to the chassis, about a vertical axis, an attachment device for attaching the chassis to the agricultural vehicle, the attachment device including at least two arms intended to link the chassis to the agricultural vehicle, and each carrying two pivot links that together define a deformable parallelogram.

A method for assisting a coupling operation to be carried out at a three-point powerlift of an agricultural tractor includes determining via a control unit in communication with an imaging device using image capture and analysis a spatial actual position of implement-side coupling points of the implement interface relative to the tractor-side coupling points, steering via the control unit the agricultural tractor along a predetermined trajectory into an end position provided for the attachment of the implement, and activating via the control unit the actuator arrangement in accordance with the course of the predetermined trajectory such that the tractor-side coupling points take up a spatial desired position provided for attaching the implement-side coupling points.

A work vehicle includes: a chassis; a cab comprising a frame carried by the chassis; a support structure carried by the chassis; a hitch system directly coupled to the support structure and including a pair of lift arms, each of the lift arms being pivotably coupled to the support structure; and an anti-roll system including an anti-roll bar coupled to the frame of the cab and directly coupled to the support structure such that the support structure simultaneously supports both the hitch system and the anti-roll system. A combined hitch and anti-roll system that includes the support structure, hitch system, and anti-roll system and may be removably mounted to a vehicle is also disclosed.

A tractor includes a body, a link mechanism including a link including an end on a side of the body, and a link attachment mechanism to attach the link to an end of the body in a front-back direction, the link attachment mechanism including a shaft with an axis in a left-right direction and supporting the end of the link such that the link is rotationally movable about the axis, at least one support located on the body and supporting the shaft, and a fixing tool to disable or enable movement of the shaft in the left-right direction relative to the at least one support and to allow the shaft to be pulled out of and inserted into the at least one support in the left-right direction.

Three-point hitch mount systems for connecting an implement to a tow vehicle having two lower hitch arms and an upper link arm are disclosed. The hitch mount systems may include a lift bar configured to be attached to the two hitch arms of the tow vehicle. The hitch mount systems may include a yoke assembly. The yoke assembly includes a forward-facing slot and a downward-facing slot for removably receiving the lift bar.

A wear block assembly for a three-point hitch includes an actuator wedge that moves along a longitudinal axis relative to a lower lift arm of the three-point hitch. The actuator wedge also includes a tapered surface. The wear block assembly also includes a wear block that moves along a lateral axis relative to the lower lift arm and the wear block includes a wear surface that engages a sway block of the three-point hitch. The wear block also includes a contact surface that engages the tapered surface of the actuator wedge. The actuator wedge drives the wear block to move in a first direction along the lateral axis in response to movement of the actuator wedge in a second direction along the longitudinal axis.

A sway block assembly includes a sway block having a wear surface and a flange. The flange includes a first slot configured to receive a first fastener to secure the sway block to a member of a three-point hitch system. The wear surface is configured to contact a wear block of the three-point hitch system. The wear surface is not formed on the flange.

A lift arm for a three-point hitch includes a central body. The central body includes a connecting member and a first rib extending away from a surface of the connecting member along a lateral axis. The central body also includes a second rib extending away from the surface of the connecting member along the lateral axis. A channel is formed by the connecting member, the first rib, and the second rib.

A locking assembly for a three-point hitch quick coupler includes a locking plate configured to be movably coupled to a main support of the three-point hitch quick coupler. The locking plate is configured to block removal of a lower hitch pin from a lower hook of the three-point hitch quick coupler while the locking plate is in a closed position, and the locking plate is configured to enable removal of the lower hitch pin from the lower hook while the locking plate is in an open position. The locking assembly also includes an actuator coupled to the locking plate and configured to be coupled to the main support of the three-point hitch quick coupler. The actuator is configured to drive the locking plate to move between the open and closed positions.

An upper link for a three-point power lift of an agricultural tractor including a cylindrical connecting sleeve, a first fastening element rotated into a first open end of the cylindrical connecting sleeve and configured to be attached to the agricultural tractor, a second fastening element rotated into a second open end of the cylindrical connecting sleeve and configured to produce a releasable connection to an attachment, and a retaining bar attached to the first fastening element. The retaining bar includes a bar portion having a locking region for receiving a retaining catch and runs spaced apart along the cylindrical connecting sleeve. The retaining bar includes a support element encompassing the cylindrical connecting sleeve such that the connecting sleeve is rotationally displaceable, and the length of the upper link is varied by rotating the cylindrical connecting sleeve.
