A drawbar coupler for work vehicle has a drawbar (10) with a removable stud (18) mounted on its end such that it can engage an implement hitch. A main bracket (20) is mounted on the drawbar between the stud (18) and the work vehicle. A lockable strap (16) pivoted on the main bracket is pivotal between an engaged position close to the top of the stud (18) and a disengaged position remote from the top of the stud to allow the implement hitch access to and from the stud. The strap is lockable in at least the engaged position by a locking pin (40). The stud and strap are interchangeable to allow the coupler to be used with other implement hitches.
