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 in 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.

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  20 or 24 hp Honda.
