The Geoprobe® Model 7720DT is a high-capacity direct push machine with a narrow platform for limited access areas and a longer stroke for added work space under the hammer. This machine is equipped with many features Geoprobe® customers are accustomed to and with many new advantages for all types of field conditions. It combines a 77-in. stroke from a 7730DT machine with a 6620DT's undercarriage design. The result is additional working space under the hammer for dual tube and auger work with a more compact and lighter weight package than the 7730DT.

  • 77 in. (1956 mm) probe cylinder stroke allows use of 60 in. (1,524 mm) probe rods
  • Over 20 ton pulling capacity for today’s larger sampling tools and deeper depths
  • Equipped with the powerful GH62 Hammer
  • Built-in rotary spindle for concrete drilling, augering, and anchoring
  • Equipped with a hydraulic winch for handling augers and tripping dual tube sampling tools
