Choose Your Handle

To complete your Hydraulic earth drill, choose one of our three handle options. All handles feature a self-centering control valve for return to neutral when released.

The one-man handle is used for ordinary drilling tasks. The 150 RPM motor generates 225 ft. lbs. of torque to drive augers up to 9″ in diameter. An optional 220 RPM motor is available when higher speeds are desired.

Choose the two-man handle for drilling larger diameter (10″–16″) or extra deep holes. It features a standard 150 RPM motor. Faster (220 RPM) and slower (125 RPM) motors are available as options when hole digging requires greater drilling speed or added torque.

A high-torque anchor handle is designed for anchoring mobile homes or light utility work. At 60 RPM, the standard anchor handle generates 360 ft. lbs. of torque. Optional 125 and 150 RPM motors are also available and are ideally suited for driving bucket augers when performing foundation repair work.

By combining higher horsepower engines with the reversibility, reliability and convenience of hydraulic drive, Little Beaver Hydraulic earth drills are ideal for drilling in rocky or heavy clay soils. With their extra torque, these powerful earth drills can handle augers up to 16″ in diameter and can drill depths of up to 30´ with 12″ or smaller diameter augers, depending on soil conditions. A forward/reverse lever lets you remove the auger if it gets caught under an obstruction, such as a rock or tree root.

Even with all this power, most hole drilling remains a one-man operation, thanks to our patented torque tube. The torque tube eliminates the kickback common with competitive earth drills, making one-man drilling safe, fast and productive. Convenient front and rear handles make it easy to load the Hydraulic earth drill into and out of your truck.

Telescoping Torque Tube

The Telescoping Torque Tube Kit allows the power source to remain on a vehicle while the included two-man handle is used to drill holes up to 11 feet away. The kit is perfect for drilling along roadways or other accessible areas, and also allows attachment to any equipment that has auxiliary hydraulic connections.

Tripod Kit

The Little Beaver Tripod Kit allows controlled drilling and easy 4″ auger removal up to 35′ deep. Designed for soil sampling and geophysical work, the Tripod Kit features fast set-up and a hand winch, and is compatible with both one- and two-man handles.

General Purpose Hydraulic Power Source

The General Purpose Hydraulic Power Source powers Little Beaver earth drills and a broad array of other hydraulic tools, including concrete saws, breakers, tampers, and chain saws. This versatile Power Source features an attaching point for the torque tube, oil cooler with 10″ fan and a 4 gallon fuel tank for dependable, all day operation. The Power Source can be secured in the back of a truck or mounted on optional two or three wheel carriages for in-the-field portability and maneuverability.

Towable Hydraulic Earth Drills | Little Beaver Inc

The HYD-TB11H features convenient forward and reverse auger rotation and a two-position handle that permits drilling right next to buildings or other structures. Our goal was to design a towable, hydraulic earth drill that was clearly superior to any competitive offering currently on the market. When we designed the HYD-TB11H, we weren’t interested in developing an ordinary, “me too” machine.


UN-Towable Hydraulic Earth Drill | Little Beaver Inc

The E-Z load bracket slide-in receiver hitch allows the unit to be hauled by any vehicle that is equipped with a 2-inch slide-in receiver, eliminating the need for a trailer or additional vehicle to transport when truck bed space is tight. The NTV11H is economically priced, without sacrificing the power, efficiency, and reliability of similar towable units, and incorporates heavy-duty construction and high quality components.


Earth Drilling Equipment and Accesories

Little beaver will be attending the following trade shows this year. Stop by and check out or equipment or just say hi.


Mechanical Earth Drills | Little Beaver Inc

A convenient snap button holds the auger securely to the transmission adaptor and lets you easily connect or remove augers and extensions without pins or tools. Little Beaver’s horizontal boring options easily convert your earth drill into a cost effective horizontal boring machine. The engine throttle control and the on/off switch are conveniently located on the left handle.


Augers, Extensions, Points & Blades

Available in both full flighted and tube versions, these extensions are equipped with a spring-loaded snap button for fast, yet secure connections. Lengths, Little Beaver snap-on augers feature heavy-duty flighting, replaceable/reversible blades and a secure snap button connection. To ensure maximum digging efficiency and auger life, the point and blade should be replaced when they become dull.


Accessories & Adapters | Little Beaver Inc

We manufacture a number of kits, accessories and adapters that turn your Little Beaver into a horizontal boring machine, foundation repair tool, or anchor driver. You can even use your current brand of earth drill or auger in conjunction with Little Beaver’s earth drills and augers. Little Beaver is designed to do more than just drill vertical holes.
