Abstract
A sulky apparatus and method are described. The sulky rides behind a self-propelled mower. The sulky apparatus allows the mower operator to ride behind the mower, as the self-propelled mower is guided about a lawn. Common to the sulky apparatus is a swing arm that extends from the mower to the sulky. The invention comprises a locking mechanism including a footpad having an elongated locating pin extending from the footpad. The pin acts against a coil spring. The operator while continuing to stand on the sulky, forces the footpad and pin against the bias of the coil spring. The pin is then projected into an aperture disposed in a top portion of the sulky, thus locking the mower and sulky together in straight position alignment. Once locked, the mower and sulky can be driven in reverse.
