An excavation apparatus especially useful when mounted on backhoes and other lighter vehicles used in the construction industry. The excavation apparatus does not require a winch for letting out and retracting its cable nor a reel for storing retracted cable which reduces the weight of the excavation apparatus, lowers its cost while facilitating both operation and servicing. The apparatus has a kelly assembly housing which houses an outer kelly section, and an extendable innermost kelly section adaptable for attachment of a tool. More than one extendable kelly section can be used. A rotary table rotates the kelly sections. A support structure supports the rotary table and the housing. A frame allows the housing to slide relative to the frame in a direction parallel to the axis of the assembly. A downcrowd mechanism, supported by the frame, downcrowds the support structure relative to the frame. A kelly deployment and retraction mechanism deploys all extendable inner kelly sections out of the housing and retracts them back into the housing. This mechanism has at least one kelly extension sheave supported by the frame, and a cable having one end attached to the innermost kelly section and a second end attached to either the support mechanism or the frame. The cable is alternately looped under lower extension, and over upper, extension sheaves so that the downcrowd mechanism also serves for letting out and retracting the cable.
