The design of the Geoprobe® Model 6610DT direct push machine offers the complete package. From auxiliary power sources, a workhorse hammer, and a well-planned work area. The tracks allow this direct push machine to be used on concrete and pavement as well as off-road and rugged terrain. The width of the machine is 48 inches with the narrow undercarriage providing excellent access to tight locations for probing and drilling. The machine is equipped with augering capabilities, a winch to help with tool placement, and a DH100 Auto Drop Hammer. The 6610DT Geoprobe can flexibly switch from environmental to geotechnical work with little time and effort. The Geoprobe DH100 Auto Drop Hammer allows the collection of Standard Penetration Test (SPT) data which conforms to ASTM D1586-99. The machine also includes a wireless remote control, onboard tool storage, and an accessible engine compartment for quick systems checks.

Water Transport System provides 25 gallons of water in a polyethylene water tank.


Overhead Mast and Hydraulic Winch aids in the heavy lifting of large tooling and augers. Also helpful for tripping dual tube samplers. Lifting capacity is approximately 3,000 pounds.


GA3000 Augerhead swings out from mount enabling 5 minutes changes from direct push. Capable of holes from 2.5 in to 9.75 in OD.


DH100 Automatic Drop Hammer allows geotechnical standard penetration tests. Uses auxiliary hydraulics on machine for repeatable and accurate blow count results.
