Abstract
A novel center pivot hitch assembly mechanism is disclosed. The mechanism of the present invention is preferably carried by a wheeled tool bar and a wheeled agricultural implement. The wheeled agricultural implement or cart is typically moved along a path by a tractor. The mechanism of the present invention pivotally connects the wheeled tool bar to the backside of the cart. The mechanism of the present invention comprises a center pivot hitch assembly and a stabilization assembly. The center pivot hitch assembly selectively allows the wheeled tool bar to pivot transversely and vertically in relation to the path along which the wheeled agricultural implement is being moved. The stabilization assembly includes hydraulic fluid actuator means for selectively maintaining tool bar disposition relative to the agricultural implement backside, when the wheeled tool bar is oriented substantially parallel to the backside of the wheeled agricultural implement. An additional feature of the present invention, which causes overhung load on the wheeled tool bar to be centered substantially along the axle of the wheeled agricultural implement when the tool bar is also disclosed.
