    The MHD is a completely hydraulic unit designed to provide more drilling capacity than
    comparably sized rigs. The easy to use controls and simplified design make the MHD more
    operator and mechanic friendly. This unit can be mounted on a 3 axle truck or crawler
    undercarriage. Made to drill up to 100 feet, the MHD combines the power, versatility, and
    efficiency needed to give you confidence on any job.
