Abstract
An automated variable speed control system for a cutter head of a dredging cutter has a cutter head and a pump. The pump pumps cuttings from the cutter head through a cuttings discharge line. A sensor monitors amperage draw of the pump. A controller controls speed of movement of the cutter head based upon data received from the sensor. The controller increases a speed of movement of the cutter head through the materials when the amperage draw of the pump falls below the determined amperage range and the controller decreases the speed of movement of the cutter head through the materials when the amperage draw of the pump exceeds the determined amperage range.
