ABSTRACT:
The riding lawn mower includes a prime mover supported on wheels for movement over the ground, a blade housing carrying one or more cutter blades and having leading and trailing end portions, one or more ground engaging wheels partially supporting the blade housing for gaging the distance the leading end portion of the blade housing travels above the ground, and a suspension system mounting the trailing end portion of the blade housing on the front end of the prime mover and arranged to transfer a portion of the weight of the blade housing to the prime mover so that the prime mover front wheels gage the distance and trailing end portion of the blade housing travels above the ground. The suspension system includes one or more longitudinally extending push arms, a mount pivotally mounting one end of each push arm on the prime mover for pivotal movement of the push arm relative to the prime mover about a first generally horizontal axis, and a mount pivotally mounting the other end of each push arm on the trailing end portion of the blade housing for permitting upward pivotal movement of the trailing end portion of the blade housing relative to the push arm about a second generally horizontal axis and for limiting downward pivotal movement of the trailing end portion relative to the push arm about the second axis and thereby controlling the minimum distance the trailing end portion travels above the ground.
