Rheonetic Seat Suspension System

The Rheonetic Seat Suspension System consists of (a) a seat damper cylinder that is filled with a magnetic fluid, (b) a sensor that detects vibration and jolting, and (c) an electronic controller that creates a magnetic field to thicken the fluid and dampen the movement of the seat. The fluid can change from a free-flowing liquid to a near-solid instantly, then back to a liquid when the magnetic field is removed. The thicker the fluid, the greater the damping forces provided. This damper can be mounted in place of most tractor seat suspension cylinders.

Cost: $300 (RD-1005-3)
