GEOPROBE® MODEL 7730DT

The Geoprobe® Model 7730DT is a high-capacity direct push machine with a durable undercarriage, hollow stem auger capabilities, and a wide-base platform.

The heart of the newest Geoprobe® Direct Push Machine ... the Model 7730DT, is the powerful GH62 hammer which Geoprobe Systems® designed specifically for direct push applications. A dependable 75 hp Kubota 4-cylinder turbo diesel engine powers all of the hydraulics used on the machine.

The undercarriage of the Model 7730DT is 18 in. wider than the Model 6620DT which adds stability in the field for deep subsurface work and augering. It’s a great foundation to support all the work you can do with the two-speed auger head, an overhead mast and hydraulic winch, and two-speed probe cylinder.
