Abstract: A coupler for a pickup drawbar has a removable stud mounted to the end of the drawbar for engaging an implement hitch. A main bracket is mounted to the drawbar between the stud and the work vehicle. A top strap is pivotally mounted in the main bracket and is pivotal between a position engaging the top of the stud and a position removed therefrom to allow the implement hitch access to and from the stud. The top strap is lockable in its closed position engaging the stud and preferably also in its fully open position laying back against the drawbar. The coupler is readily modifiable for use with various implement hitches simply by replacing the stud and top strap.
