Abstract
A lawn mower includes a front wheel suspension system as well as a rear wheel suspension system. The front wheel suspension system includes upper and lower suspension struts that are pivotably connected between a main frame of the lawn mower and a longitudinal suspension strut that is connected to a front wheel. A spring is connected between an extension of the upper suspension strut and a front transverse member of the main frame. The rear wheel suspension system includes upper and lower links that are pivotably connected between vertical struts that are connected between upper and lower frame members of the main frame and a motor mount. A spring is connected between a spring bracket extending from the upper frame member and either the motor mount or a motor mounted in the motor mount. In order to prevent scalping while turning, a floating cutter deck is suspended from the front and rear wheel suspension systems rather than from the main frame or chassis of the mower. An alternative embodiment includes a hinged pivoting subframe with springs between the main frame and the left and right halves of the subframe. In this alternative embodiment, the front of the cutter deck is suspended from the main frame while the rear of the cutter deck is suspended from the rear wheel suspension system.
