Patent abstract
A suspended operator platform for use with a ride-on lawnmower or the like is connected to a rigid chassis of the ride-on lawnmower by a suspension system that has a parallelogram linkage. The operator platform supports an entire body of the operator and isolation mounts connect a seat assembly to the operator platform. Steering controls of the ride-on lawnmower are connected to the operator platform so that the steering controls move with the operator platform and are suspended and/or isolated from the chassis. The suspension system includes a course-stiffness adjuster and a fine-stiffness adjuster that adjust the suspension stiffness to correspond to a particular operator and/or terrain.
