ABSTRACT:
A soft excavator (10, 90, 110, 130) is disclosed which utilizes a jet of high velocity fluid flow such as air or water flow, preferably supersonic, through a nozzle (48, 92, 112) to excavate a material, such as the ground. A second passage for air flow is provided which is directed by an evacuator skirt (52, 102) in a direction along the excavator generally opposite the direction of discharge of the high velocity excavating flow to entrain the material excavated for disposal.
