Abstract: A system can include a boom assembly operably coupled with a chassis. A first actuator can be operably coupled with a first pair of sections of the boom assembly. A second actuator can be operably coupled with a second pair of sections of the boom assembly. A sensor system can be configured to capture data indicative of one or more operating conditions of the boom assembly. A computing system can be communicatively coupled to the first actuator, the second actuator, and the sensor system. The computing system can be configured to receive the data from the sensor system, determine a current boom profile of the boom assembly, determine a current ground profile relative to the boom assembly, and determine a first position for the first actuator to place the boom assembly in a target boom profile.

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.
