Abstract
A hitch includes a control linkage having a single handle on a control bar. The control linkage doubles to provide both a positive safety feature and a movement feature to the hitch, permitting single handed operation of both the positive safety feature and the opening of the hitch with the single handle. A release throw of four inches or less opens jaws of the hitch. A latch is included which can secure the control bar in either a secured position or in a release position. A follower is secured to one of the jaws to maintain timing between the jaws, and the follower doubles as a hitch position indicator so an operator to easily visually discern the position of the hitch. By including kingpin recesses of appropriate location and depth on the jaws, the hitch can be used with or without a lube plate over the skid plate.
