Hitch device for agricultural vehicle

A hitch device for an implement, suitable for being mounted on an agricultural vehicle, wherein said hitch device comprises:

• a chassis transverse to the direction of travel of the hitch;
• a system for coupling an agricultural implement to said chassis, said coupling system being designed to pivot freely relative to the chassis, about a vertical axis;
• and
• an attachment device for attaching the chassis to the agricultural vehicle, the attachment device comprising at least two arms provided with an activation means and intended to link the chassis to the agricultural vehicle, said at least two arms extend in a direction substantially parallel to the direction of travel of the hitch, each of the at least two arms comprising, at a proximal end thereof relative to the chassis, a first pivot link with the chassis, allowing each arm to pivot relative to the chassis about the vertical axis, as well as a second pivot link with the agricultural vehicle, allowing each arm to pivot relative to the agricultural vehicle about the vertical axis, a set of four pivot links when viewed from above thus defining a deformable parallelogram in a horizontal plane perpendicular to the vertical axis that is deformable under the action of the activation means,
• the second pivot link of the at least two arms is disposed at a distal end thereof relative to the chassis, with said distal end also forming an attachment for attaching said at least two arms to the agricultural vehicle, and said at least two arms each have an elbow, the convexity of said elbow is laterally outward facing, the at least two arms defining a clearance horizontally curved about the vertical axis to avoid interference with elements of the agricultural vehicle comprising tow bars, hitch devices for a towed implement, and a means for controlling powered implements,
• wherein said at least two arms include a first arm and a second arm,
• said first arm and said second arm each have said first pivot link connecting to the chassis and said second pivot link connecting to the agricultural vehicle,
• the second pivot link of each of said first arm and said second arm being laterally displaced from each other,
• the first pivot link of each of said first arm and said second arm being laterally displaced the same amount as the second pivot link so that the attachment of said first pivot link to the chassis reflects lateral displacement, and
• said lateral displacement of said first pivot link and said second pivot link form said parallelogram.
