A quick connect/disconnect coupling for securing an agricultural implement, such as a stalk stomper, to a tool bar assembly on a tractor, without the need for any tools. The tool bar assembly includes a bracket having a pair of spaced-apart arm members. Each arm member has a recess therein, and a hole spaced therefrom. The recesses and the holes are generally transversely aligned. A pin is adapted to be received in the holes. The agricultural implement includes a plate member. Provided on the plate member are a cross bar and a retention stop. The cross bar is adapted to be engaged in the recesses. To connect the agricultural implement to the tool bar assembly, the cross bar is engaged in the recesses and the agricultural implement is pivoted so that the plate member is above the pair of holes and the pin can be inserted into the transversely aligned holes to connect the agricultural implement to the tool bar assembly. The pin engages the retention stop so as to prevent longitudinal movement of the stalk stomper with respect to the tool bar assembly in operation and thereby prevent the cross bar from disengaging from the recesses. To disconnect the agricultural implement from the tool bar assembly, the pin is removed from the transversely aligned holes and the cross bar is disengaged from the recesses.
