Hydraulic Earth Augers		  

75 Series Planetary Drive Units


All 75 Series Drive Units are engineered with McMillen's "In-Line" drive design, to eliminate chain and sprocket reductions. A hydraulic motor drives the auger through a sealed planetary gear reduction. The heavy duty all gear design of McMillen's planetary drives gives these units a long life with minimal maintenance and service costs.
