Abstract: A material spreader includes a belt/chain assembly. The belt is mounted within the chamber of the material spreader and the chain remains out of contact with the material during the operation of the device. A sliding barrier is mounted at the rear of the belt, and moves from a forward position adjacent the front of the spreader to a rear position adjacent the rear of the spreader. One form of the hydraulic system utilizes a sensor for built up pressure within independently driven augers. In response to this pressure build up the sliding barrier speed is reduced.

Abstract: A boom assembly is provided for use on a vehicle. The boom assembly utilizes various suspension components which absorb and damp a significant amount of various loads imparted on the boom assembly during operation of the vehicle. The boom assembly reduces the loads imparted on the booms when the vehicle pitches and rolls. By reducing the loads created by vehicle pitching and rolling, the booms receive a softer and smoother ride which increases the lifetime of the booms and lengthens the time between repair of the booms.
