Geoprobe® Model 7822DT

The 7822DT was designed with ‘Serviceability’ in mind, from the lift-up lid on the engine compartment to easy access to the battery, fuses, and relay panel.
The control panel was totally redesigned and features thumb-dial control for the auxiliary hydraulics, more options, more controls, and more feedback for machine operators.
