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.

Abstract: A mouth-blown pneumatic system for launching disks used to play games, and the like, which includes a hollow housing having an air reservoir therein, a hose with one end connected to the air reservoir and the other end connected to a mouthpiece for blowing air thereinto, a disk launching chamber, a disk launching ramp within the disk launching chamber, a baffle inside the housing separating the air reservoir and the disk launching chamber, and a manually-operable valve for controlling the flow of air from the air reservoir to the disk launching chamber.
