Abstract
A device for automatically coupling an implement to a vehicle comprises a rigid frame pivotally mounted on the chassis of the vehicle and extending generally horizontally therefrom. A hitching frame is pivotally mounted on the horizontal frame and carries upper and lower pairs of hitching jaws engageable with horizontal support bars of the implement. A double-acting ram is operatively connected to the hitching frame to pivot the hitching frame relative to the rigid frame during coupling and uncoupling operations.

In a self-propelled vehicle,
- a chassis, and
- a device mounted on the chassis for automatically coupling an implement having an upper and a lower supporting bar to the vehicle, said device comprising
- a rigid member having opposed end portions, said member being pivotally connected at one end portion to the chassis and extending generally horizontally,
- lifting means pivotally mounted on its one end to a chassis,
- suspension means connecting said rigid member to the lifting means,
- a hitching frame pivotally mounted at the lower end portion of the rigid member, said hitching frame including a pair of upper jaws engageable with said upper supporting bar and a pair of lower jaws engageable with said lower supporting bar for engaging the implement, and
- a double-acting ram operative to pivot the hitching frame and extending between the rigid member and the upper end portion of the hitching frame.
