    • A hitch assembly (100) is disclosed. The hitch assembly (100) comprising: a main frame (110) comprising a projection (118); a first link (120) pivotably coupled to the main frame (110); a second link (130) pivotably coupled to the first link (120) by a pivot pin (102); and a self-locking actuator mechanism (200), comprising: a floating plate (210) defining a first slot (230), the first slot (230) comprising a first central portion (232), a first jog (235) extending laterally from a first end of the first central portion (232), and a second jog (238) extending laterally from a second end of the first central portion (232), wherein the projection (118) extends into the first slot (230), and wherein the floating plate (210) is pivotably coupled to the first link (120) and the second link (130); and a linear actuator (220) mounted to the main frame (110), the linear actuator (220) comprising a shaft (224) pivotably connected to the floating plate (210); wherein the hitch assembly (100) has a first state in which the shaft (224) is in a first shaft position, the floating plate (210) is in a first plate position, and the projection (118) is received in the first jog (235) to thereby lock the first link (120) and the second link (130) at a first relative orientation; wherein the hitch assembly (100) has a second state in which the shaft (224) is in a second shaft position, the floating plate (210) is in a second plate position, and the projection (118) is received in the second jog (238) to thereby lock the first link (120) and the second link (130) at a second relative orientation different from the first relative orientation; and wherein the linear actuator (220) is operable to drive the shaft (224) between the first shaft position and the second shaft position to thereby move the hitch assembly (100) between the first state and the second state. Furthermore, a method of operating such hitch assembly (100) is disclosed.

    • A towed implement (10) for use with a work machine includes a main frame (12) having a pivot hole (32) and at least one hitch mounting hole (34). A hitch frame (18) is coupled with the main frame (12) and includes a towed end (22). A height adjustment arrangement (20, 70, 80) is associated with the main frame (12) and the hitch frame (18) for adjusting a height of the hitch frame (18). The implement (10) is characterized in that the hitch frame (18) is pivotable relative to the main frame (12) about a pivot axis (A) at the pivot hole (32). The hitch frame (18) includes a chamber (40, 90) having an interior periphery (42) with a plurality of notches (44) spaced about the interior periphery (42). The height adjustment arrangement (20, 70, 80) includes a stop key (46) positioned within the chamber (40, 90) of the hitch frame (18). The stop key (46) has a hole (48) arranged for receiving a fastener associated with the at least one hitch mounting hole (34), a cam surface (52), and at least one tooth (54) extending from the cam surface (52). Each tooth (54) is received in a corresponding notch (44) of the interior periphery (42).

    • A method for providing improved ride control for a work vehicle when transporting a drawn implement may include monitoring a load applied through a drawbar-related component(s) of the work vehicle while the drawn implement is being transported, wherein the drawn implement is located at a transport position relative to a driving surface of the work vehicle such that a ground engaging tool of the drawn implement is located above the driving surface. The method may also include detecting a variation in the monitored load over time, comparing the detected load variation in the monitored load to a predetermined load variance threshold and controlling an operation of at least one of an implement suspension system of the drawn implement or a vehicle suspension system of the work vehicle so as to reduce the detected load variation in the monitored load when the load variation exceeds the predetermined load variance threshold.
