The HTC 950 RX's radio control simplifies the work and extends the grinding time per day. The work also becomes more efficient since dust extractors can be emptied and cables handled while the machine is run on radio control. Four grinding heads result in less operator fatigue and a balanced grind. A battery backup allows you to drive or load the machine onto a jobsite or into a trailer with no power cord connected.
