Abstract
The invention is directed to an integral coupling arrangement for coupling a trailing cart to a transverse toolbar. The cart is provided with two draft links extending forwardly from the cart that are pivotally coupled to the toolbar. A central hitch also extends forwardly from the cart and is coupled to the toolbar by a floating link. Pushing and pulling forces are applied through the draft links only. The central hitch carries the vertical weight applied by the cart.
