Toro riding mower suspension systems are engineered with carefully selected components that work together to provide you with a smooth ride on uneven turf. The cutting deck of the mower works in conjunction with the suspension system to provide a consistent quality of cut. These systems minimize shock to the chassis, and you, resulting in superior comfort, stability, traction and increased mowing efficiency. When it comes to reliability, Toro delivers replacement parts designed to the exact engineering specifications of our equipment. For peace of mind, insist on Toro genuine parts.
