You don’t run from the tough jobs, so make sure to bring a machine that has your back. And, a machine that does these kinds of jobs can’t have a weak link – it has to be designed top-to-bottom with tried-and-tested materials and components. The EHD unit includes an extreme-duty TEFC motor, solid steel, harsh duty gear box and coupler system, optional 40 pound weight kit, and a 10-year base warranty.
