ABSTRACT:
A hitch for connecting an agricultural implement to a tractor including an A-frame secured to the upper side of a transverse draw bar, the draw bar having a plurality of link-engaging brackets at its opposite ends for engaging the lateral lifting links of the tractor, and further having a clevis bracket at its central portion and on the opposite side of the draw bar from the link-engaging brackets for connecting the tongue of an agricultural implement thereto. The hitch further includes a cylinder-supporting plate projecting from a central crossbar of the A-frame to a position over the clevis bracket and supporting on the upper side thereof, a hydraulic cylinder which has its upper end pivotally connected through a suitable bracket to a plate secured to the apex of the A-frame. A piston rod extends from the lower end of the cylinder through the supporting plate provided therefor, and is pivotally connected through a flexible joint to a connecting pin which is positioned to be extended through a pair of vertically aligned apertures in the clevis bracket. On the opposite side of the A-frame crossbar from the cylinder-supporting plate, a pair of central link bracket plates project horizontally from the crossbar and contain a pair of aligned apertures to facilitate connection of the central adjusting link of the three hitching elements of a tractor to the hitch.
