Abstract: A conversion backhoe-to-crane type system, including preferably a box type, 50' boom and two, hydraulically driven cable or line winches, the hoist one of which is mounted directly on the crane-like boom. The winches have "true free fall" characteristics, by using a high torque, radial piston hydraulic motor directly driving the drum, which motor cn be put into a "neutral" disposition, exerting no significant drag on the cable winch drum when it unwinds under the force of the suspended load and/or work implement falling under the force of gravity. Additionally, a supplemental braking system, e.g. a disc brake carried on the winch drum shaft, is added. Thus, the winch drum becomes truly free wheeling, when the hydraulic winch is put in "neutral," but can still be controlled, when desired, by the supplemental disc brake sub-system. A second, spring apply, disc brake is included for emergency back-up. For exemplary purposes, the backhoe conversion is illustrated in a dragline configuration (FIG.
