1. A garden implement comprising:
- a frame comprising a lower frame portion including two spaced-apart leg portions, and an upper frame portion comprising two spaced-apart handles;
a hub motor assembly comprising a horizontal non-rotating shaft, a hub motor mounted on the shaft for rotation thereabout, and a hub body encompassing the hub motor and operative to be rotatably driven by the hub motor, the hub body having an outer surface extending coaxially about the shaft, the shaft protruding laterally outward from the hub body on a left and right side thereof, the leg portions of the lower frame portion being selectively couplable to the shaft;
a working tool couplable to the hub body, the working tool comprising a plurality of working tool segments serially coupled together and mountable at the outer surface of the hub body extending coaxially about the shaft, the working tool segments being removably clampable to the hub body and configured to rotate therewith as the hub body is rotatably driven by the hub motor; and
a power supply module coupled to the frame and operatively coupled to the hub motor to provide electrical power thereto.

Abstract
A garden implement that utilizes a hub motor assembly coupled to a frame. One or more working tools may be selectively coupled to a hub body encompassing a hub motor of the hub motor assembly. The working tools are operative to work soil in a garden or other agricultural setting. The hub motor may include a brushless DC motor driven by an electrical power source. The electrical power source may include a battery or an AC power source. Alternatively, the hub motor may be used to drive a wheel which propels the garden implement.

23. A garden implement comprising:
-
a frame comprising a lower frame portion including two spaced-apart leg portions, and an upper frame portion comprising two spaced-apart handles; a hub motor assembly comprising a horizontal non-rotating shaft, a hub motor mounted on the shaft for rotation thereabout, and a hub body encompassing the hub motor and operative to be rotatably driven by the hub motor, the shaft protruding laterally outward from the hub body on a left and right side thereof, the leg portions of the lower frame portion being selectively couplable to the shaft; a working tool couplable to the hub body and configured to rotate therewith as the hub body is rotatably driven by the hub motor; and a power supply module coupled to the frame and operatively coupled to the hub motor to provide electrical power thereto; wherein the working tool comprises; a first substantially semicircular section having a first end and a second end, and a plurality of tines therebetween; a second substantially semicircular section having a first end and a second end, and a plurality of tines therebetween; and a coupler attached to the first end of the first substantially semicircular section and the first end of the second substantially semicircular section such that the first and second substantially semicircular subsections are pivotally coupled together at their respective first ends and movable between an open position wherein the respective second ends are spaced-apart from each other such that the working tool may be freely removed from the hub body, and a closed position wherein the respective second ends are substantially adjacent to each other such that the working tool may be selectively clamped around the hub body for rotation with the hub body. - View Dependent Claims (24)

25. A garden implement comprising:
-
a frame comprising a first end portion including at least one axle supporting member, and a second end portion comprising a handle; a hub motor assembly comprising a horizontal non-rotating shaft, a hub motor mounted on the shaft for rotation thereabout, and a hub body encompassing the hub motor and operative to be rotatably driven by the hub motor, the shaft protruding laterally outward from the hub body on a left and right side thereof, the at least one axle supporting member being selectively couplable to the shaft; a working tool couplable to the hub body, the working tool comprising a plurality of working tool segments serially coupled together and removably mountable in a position extending circumferentially about the hub body and configured to engage soil and rotate with the hub body as the hub body is rotatably driven by the hub motor; and a power supply module coupled to the frame and operatively coupled to the hub motor to provide electrical power thereto.
