Abstract
A safety sulky for a self-propelled mower. The safety sulky has a chamber adjacent a platform upon which a mowing operator stands. Two, spaced-apart pins that are biased downwardly by a spring can be made to rise above the chamber by two levers. The two, spaced-apart, spring-biased pins can project through the upper surface of the chamber by standing on the levers. The pins operatively engage with, and rise adjacent to, the elongated arm thus intersecting the swing path of the sulky about the connecting arm, limiting its arcuate movement.
