ABSTRACT:
Longitudinally extending main and motor and drive frames are provided with the frames supported from each other for relative angular displacement about a horizontal central axis extending longitudinally of the frames and about an upstanding axis spaced centrally intermediate the opposite ends of the frames. The motor and drive frame include motor driven ground engageable drive structure and the main frame includes support structure for supporting a depending earthworking tool. Adjustment structure is provided for releasably retaining the main and motor and drive frames in adjusted angularly displaced positions relative to each other about both the horizontal and upstanding axes and the motor and drive frame includes rear elevated hand grip structure angularly displaceable with the motor and drive frame relative to the main frame. Further, the support structure for the depending earthworking tool is oscillatably supported from the main frame for angular displacement about a horizontal axis extending longitudinally of the main frame and control structure is provided for adjustably angularly displacing the support structure relative to the main frame inversely relative to angular displacement of the motor and drive frame relative to the main frame.
