ABSTRACT:
A riding or walk-behind self-propelled lawn mower has pivoted rear axles so that the mower is steerable to a low turning radius as measured off a lateral edge of the mower deck. The rear wheels are supported on a crossbar which is fixed at its middle to the main frame, supports at its ends double universal joints, each of which drives one of the rear wheels, and together with the frame provides spaces into which the rear wheels may pivot during a minimum radius turn. The front wheels may be steerable or free pivoted casters.
