ABSTRACT OF THE DISCLOSURE A tenon-and-mortise coupler for releasably connecting any type of work implement to the front chassis of any conventional tractor. The tenon part defines an open frame, fixedly secured at its rear end to the front bottom of the tractor chassis, and tapered at its front end. The mortise part defines a hollow tapered casing, fixedly secured at its small end to the bracket assembly of the work implement and frictionally engageable by the tenon tapered end at its opposite large open end or mouth. A manually-operated lever is transversely mounted in the tenon part and defines an intermediate offset section carrying a longitudinally-extending latch bar, which is guided for combined longitudinal and vertical movement between a forward and lowered retracted position and a rearward and upper latching position. The tenon-and-mortise parts are first assembled with the latch bar in retracted position. Then the lever is rotated to bring the latch bar in latching position in which it engages the rear end of a slot made in the top wall of the mortise part. A compression spring is located between the lever and the latch bar to constantly bias the latch bar against the rear end of the slot, in order to prevent any play between the tenon and mortise parts.
