1. A portable hand operated two wheel golf course sandtrap type surface breaking and smoothing device of the attendant guided type where the attendant walks and guides the device through sandtraps; said device comprising: a frame including a pair of generally like shaped vertical basic frame members disposed in laterally spaced apart relationship; a pair of surface engaging wheels rotatively mounted on and supporting said basic frame members; a generally flat motor and implement mounting structure secured to the top portion of said basic frame members; motor means mounted on said motor and implement mounting structure; means operatively connecting said motor means with said wheels to drive the same; an attendant guide and control means including a handle fixed to said frame and extending generally upwardly therefrom where the upper end thereof has a hand gripping portion; an implement mounting sleeve fixed to said frame on the side opposite said handle and projecting generally rearwardly and downwardly therefrom; an implement mounting arm slideably confined within said implement mounting sleeve and projecting generally downwardly therefrom; releasable securing means associated with said implement mounting sleeve for adjustably securing said implement mounting arm therein; and a surface working element secured to the lower end of said iMplement mounting arm rearwardly of said wheels and including a series of transversely aligned hingedly mounted tine plates each having a plurality of surface penetrating tines and a smoothing means in the form of an impervious plate having serrations along one edge thereof whereby a smooth, loose surface can be mechanizingly produced, and wherein the hinged connection between respective tine plates enable the working element to be foldable about at least a single axis extending parallel to the path of travel of the device and allow the working element to more accurately follow the contour of the sandtrap in which employed.
