ABSTRACT:
A hand held garden tool that utilizes rechargeable batteries and a variable speed, reversible motor as its power source. A drive shaft housing serves as a long handle member and contains a drive shaft. The drive shaft and its housing are connected to, and removable from the power unit. The drive shaft extends to a small, compact drive assembly which rotates a short shaft extending to each side. Each shaft holds two tine discs. The curved tines on the tine discs rotate closely around the perimeter of the drive assembly to speedily and thoroughly pulverize the soil and eliminate weeds.
