The Big Beaver works in areas mounted drills can’t possibly fit. At only 26″ wide and 80″ high, the Big Beaver fits through gates and doorways and can be operated under eaves or in interior locations. On level ground, the smooth riding pneumatic wheels provide convenient one-man portability.

The Big Beaver is hydraulically driven by the Hydraulic Power Source. This compact power unit features an oil cooler with 10″ fan and a 4 gallon fuel tank for dependable, all day operation. Not only does the Hydraulic Power Source efficiently power the Big Beaver, but it also serves as an attaching point for the torque tube. For added versatility, the Hydraulic Power Source can also be used to power other hydraulic tools, including concrete saws, breakers, tampers and chain saws. Engine options include an 20, 24 or 27 hp Honda.

The Big Beaver excels at foundation repair, efficiently drilling pier holes up to 16″ in diameter. A simple crank mechanism lets you align the mast in any position up to 15 degrees from vertical.
