GEOPROBE® MODEL 6620DT

Wide tracks and a heavy-duty undercarriage provide the foundation for the Model 6620DT's robust design. The strong undercarriage allows this direct push machine to be used on concrete or pavement, and enables the machine to readily negotiate in tight, confining work areas and on off-road, rugged terrain. The machine has 12” tracks. The overall width of the machine is 60” which means the undercarriage can provide a stable base for probing and drilling operations. The strength of the undercarriage also means you can equip your machine for augering, use the winch to help with tool placement and tripping, or operate the DH66 Auto Drop Hammer for geotechnical applications. It's uniquely flexible to switch from environmental to geotechnical work with little time and effort.

The overall top ground speed of the Model 6620DT ranges from a crawl, for close maneuvering, to 4.5 mph for field movement.

A 2-speed pull cylinder on the Model 6620DT at low speed (full pulling power) will pull rods full stroke (66”) in 11 seconds. On high speed, the machine can cycle from bottom to top in less than 5 seconds.

Other features on the machine include a wireless remote control, onboard tool storage, and an easily accessible engine compartment for quick daily systems checks so you can focus your field time on field work and not maintenance.
