Abstract

Front and rear independent suspension mechanisms accommodating an increased range of motion to better absorb shock originating at the wheels of a riding mower to insulate the operator and reduce stress on the mower chassis and other mechanical components. The front suspension can include a front axle with pivot pockets allowing 360 degree rotation of pivots engaged within the pockets, thereby providing a greater range of absorption of shock entering the front axle at varying angles. The rear suspension can include a vertically pivoting transmission platform, providing for controlled vertical motion in the transmission while the transmission is powered by an engine by way of a belt assembly.
