The Extreme Duty Series 2 auger drive is built for operators who need dependable drilling power across a wide range of ground conditions and machine hydraulic setups. Designed for skid steers, this heavy-duty drive lineup combines high torque output, reinforced construction, and multiple model choices to support everything from general earth drilling to more demanding clay and shale applications.
Its compact high-torque gearbox and two-piece shaft design help maximize side load performance while maintaining stable, efficient drilling. The universal skid steer mount uses a welded cradle and dual-pin layout to allow the auger to hang naturally, helping improve hole alignment and drilling control in the field.
With standard-flow and high-flow models available, this auger drive series gives operators flexibility to match the drive to their machine and job requirements. Optional bits, extensions, adapters, and a telescopic skid steer mount further expand its usefulness for fencing, landscaping, construction, and utility installation work.
