MB Crusher offers a line of drum cutters with a direct drive twin-motor system that allows for the differential distribution of power to the two rotary cutting heads. The MB-R drum cutter line can handle job sites where standard excavation systems are underpowered and hammer systems are ineffective. They are compact, powerful tools that can be attached to a range of heavy machinery. The cutters are manufactured to increase stability and reduce stress on the machine arm. Power comes from the hydraulic system of the machine it is attached to. MB’s drum cutters have a hydraulic control system that automatically manages calibration and hydraulic cooling during operations. There are several different models to choose from, depending on the operating weight of the machinery. 855-622-7874; www.mbamerica.com.
