In an agricultural drawbar, a novel foldable wing hitch assembly is employed such that when the agricultural drawbar is in a transport position, wing hitches and wing hitch support arms are folded inwardly in a scissor-like manner, thereby obtaining a very narrow transport width. Depending upon the end use of the drawbar, the wing hitch can be constructed from one piece, or in two sections with a pivotal connection. A lockable pin placed in the pivotal connection between the two wing hitch sections maintains them in direct alignment such that the drawbar can be backed up with the centre and wing sections of the main boom remaining extended transverse to the line of travel. |
