The Big Beaver is the most powerful earth drill produced by Little Beaver, the leading manufacturer of torque-free, one-man earth drills. Ideally suited for drilling environmental test wells, soil sampling and foundation repair, the Big Beaver offers one-man operation and portability to get into areas inaccessible to truck mounted units.

The Big Beaver is designed to work with 4"–18" D-series augers. When deep holes are required, auger extensions can be added to let you drill down to 30' with a 16" auger and up to 100' with a 6" auger, depending on soil conditions.
When removing an auger from a hole, the optional auger fork securely holds the auger and extensions while disconnected from the drill head.
A lift ring on the auger adaptor makes quick work of pulling augers, eliminating the need for precise alignment.


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 18 hp Briggs & Stratton and a 20 hp Honda.


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 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. An optional
belling tool is used to create an under-reamed footing at the bottom of
the foundation pier hole.
