A hitch is provided including a tongue, an insert, and a base. The tongue includes a C-shaped section having an internal spherical raceway and opposing walls, each extending from an opposite arm of the C-shaped section. The insert includes a spherical segment received within the internal spherical raceway and having a draw pin hole, and a projection extending rearward between the opposite arms of the C-shaped section and having a socket recess. The base being pivotally connected to the tongue through the opposing walls. The base includes a ball located in front of the pivotal connection, the ball being received within the socket recess of the insert, and a back end being adapted for connection to a towing implement.

A hitch assembly includes a vehicle connection interface and a rotary cutter connection interface. A mounting plate extends between the vehicle connection interface and the rotary cutter connection interface. A pivot plate is pivotally coupled to the mounting plate. A suspension element coupled between the pivot and mounting plates mitigates force transfer between the connection interfaces resulting from the relative movement of the connection interfaces.

A working vehicle includes a traveling body including a coupler to which a working device is connected, a marker provided to the working device, a marker detector provided to the traveling body to detect the marker, and a status calculator to calculate a status of the working device based on a detection data detected by the marker detector.

A tillage implement includes an implement frame having a first lengthwise frame member, a second lengthwise frame member, and a lateral frame member connected to and extending between the first and second lengthwise frame members. A hitch assembly is rotatably connected to the implement frame. A wheel assembly is connected to the implement frame and moveable between a raised position and a lowered position. A rockshaft is rotatably connected to the implement frame and connected to the wheel assembly. A leveling assembly is connected to the implement frame, the rockshaft, and the hitch assembly. The leveling assembly is configured to adjust the position of the hitch assembly based on movement of the rockshaft. The leveling assembly includes an actuator connected to and aligned with a leveling link.

The present invention is an improved aftermarket lawn tractor hitch. The improved aftermarket hitch includes an upper support plate or member for attaching the plate to the tractor, a hitch pin for connecting to the towable implement, a compression spring surrounding the pin for holding the hitch pin in a closed position, and a lower support member. The user can open the hitch pin by lifting the handle on one end of the pin thereby releasing the tongue of the towable implement, which is held between the lower support member and the conventional tow tab.

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.

An implement guidance module is provided for positioning a drawn implement as the implement is pulled by a vehicle traveling along a desired path of movement, the vehicle having a connection point for receiving a hitch. The module includes a module main frame having a first end configured for connection to the vehicle connection point, and a second end configured for connection to the implement, the main frame having a longitudinal axis, and having a pivot mount connected to the second end with an implement mounting plate pivoting relative to the module main frame about a pivot axis perpendicular to the longitudinal axis. A vehicle mounting plate defines the first end of the module main frame, and the implement mounting plate defines the second end of the module main frame.
