- Model C1000 - Drill



ARDCO’s C1000 drill is an industry standard for geophysical, geothermal and geotechnical drilling. For other applications, ask us about the ARDCO skid drill, which offers custom specs to accommodate a variety of other needs.


The K 4x4 comes standard with a Cummins QSB 6.7L diesel engine. Rated at 190 HP at 2,200 RPM, this high-torque unit offers plenty of power to get where you need.


With five forward gears and one reverse gear, the fully automatic Allison transmission features a push button shifter and adaptive shifting technology.

Transfer Case

The two-speed transfer case efficiently transfers torque to the wheels. It offers front axle disconnect for 2x4 or 4x4 performance.


Extra-heavy-duty axles are rigid-mounted to the frame. They offer heavy-duty inboard planetaries, and the front axle includes a “no-spin” feature to deliver full power to both front wheels, even when one loses traction. Driver controlled differential lock is available.


The fully enclosed inboard wet-disc brakes are pressure applied. The K 4x4 also features an emergency brake off the transfer case. It is spring applied with hydraulic release.


Durable tires offer excellent longevity, traction and floatation for traversing practically any terrain you may encounter.


The K 4x4 has a high-strength tubular steel frame with a heavy-duty articulated center pivot trunnion.


Engineered for maximum safety, the standard open-air cab is ROPS certified.


The unit is equipped with ample lighting for superior visibility. It includes LED lights at the front and rear corners of the vehicle, red rear lights and white reverse lights. It also has a flashing warning light on top of the cab.


The 16-foot welded tubular steel mast is designed for use with 10-foot (3.1 meter) drill pipe. It is raised and lowered by dual 3-inch (7.6 cm) hydraulic cylinders. Controls are conveniently located at the left rear of the drill frame.

Rotary Assembly

The top-head drive rotary assembly is hydraulically driven through 3-inch (7.6 cm) wide straight-tooth gears with a 5.923:1 gear ratio. The quill opening is 1-1/2 inch (3.8 cm) with a Carey modified 3-thread bottom box connection. The rotary quill is equipped with a special break-out sleeve, and the rotary assembly is aligned in the mast channels by specialized guides with roller bearings.


Two continuous #80 1-inch (2.5 cm) roller chains are hydraulically actuated through a Ramsey 35YR gearbox. The dual-crown idler sprocket assemblies are held by stress-proof shafts mounted in pillow blocks with adjusting bolts. The unit is also equipped with specialized heavy-duty turnbuckles for correct chain tension and rotary alignment. It offers a speed of up to 100 feet (30.5 m) per minute and pull-up/pull-down force of 6,000 pounds (2,722 kg).

Hydraulic System

A direct-drive, three-stage gear pump powers the pull-down and rotary. The K 4x4 comes standard with large-capacity hydraulic valves and high-pressure hoses. Additionally, the 80-gallon hydraulic reservoir includes 10 micron filters.

Mud Pump

The K 4x4 is equipped with a Centerline hydraulic mud pump with a continuous flow rate of 150 gpm (1,567 lpm) and 0-200 psi.

Hole Loader

The cable drum is loaded with 250 feet (76.2 m) of ¼-inch (6.4 mm) cable. It comes with a mast-mounted cable pulley and weight, and is hydraulically driven by a Char-Lynn motor.

Pipe Rack

A heavy-duty pipe storage rack is located on the right side of the drill unit.

Headache Rack

A vertically adjustable headache rack is located at the front of the drill frame.
