Abstract: A sulky apparatus attachable to a self-propelled power mower for transporting an operator in a standing position includes a rigid arm attached to the mower by a hinge which normally rotates about a horizontal axis. Operator foot-receiving platforms are supported by a wheel and are attached to the arm by means of a pivot for enabling the platforms to rotate about a normally vertical axis of the pivot. The horizontal distance between the hinge and the pivot is greater than the horizontal distance between the pivot and the rearwardmost portion of the apparatus to permit unlimited movement of the foot-receiving platforms and the wheel about the pivot axis. As a result, the mower and the apparatus can be moved in a reverse direction and the apparatus can be folded up under the handlebars of the mower.
