Some embodiments include a handle and an interchangeable tool implement including a garden tool end, a connection end, and an impact platform. Similarly, some embodiments include a drive mechanism coupled to the handle, the drive mechanism including a power source, a motor that provides rotational motion to a rotary shaft, and a piston coupled to the rotary shaft, the piston exhibiting reciprocating motion from the rotational motion, the piston making contact with the interchangeable tool implement, such that the reciprocating motion of the piston causes motion of the interchangeable tool implement. | 04-14-2011 |
| 20130175062 | TURF EDGER FOR CUTTING A CLEAN EDGE ALONG A BOUNDARY BETWEEN A TURF SURFACE AND A SOFT NON-TURF SURFACE - A turf edger is attached to a traction unit in the form of a self-propelled turf grooming or working vehicle. The turf edger has a narrow U-shaped edging blade carried on an edger frame. The edging blade oscillates to cut and free a strip of material along a boundary between a turf surface and a non-turf surface. When this strip of material is brushed away, a clean edge is provided along the boundary without the need for any manual hoeing. Side walls of the edging blade at least partially nest around a ground engaging roller on the edger frame to more easily cut horizontal grass runners in the turf surface. The edger frame is selectively movable between a lowered edging position and a raised transport position by the operator. Limited ground following action is provided for the edger frame when the edger frame is in the edging position. | 07-11-2013 |
| 20130228350 | WORK APPARATUS - A handheld work apparatus such as a bed redefiner or edger has a handle for guiding the work apparatus over the ground. The apparatus also includes a drive motor which drives a tool in rotation. During operation, the apparatus is moved over the ground by the operator in a direction of movement. The tool is covered at least partially by a protective hood and a sliding skid is arranged on that end of the protective hood located at the front in the direction of movement. The sliding skid has an abutment surface for a flexible spray guard fixed to the protective hood. The spray guard is fastened to the protective hood in its fastening region located at the front viewed in the direction of movement.
