Abstract: A rotary garden tool has cutting blades for generally horizontal cutting generally disposed in a closed loop configuration sharpened on both sides to cut while rotating in either a clockwise of counterclockwise direction. Flexible tines are designed to bend outwardly away from the cutting blades during rotation, thus creating a trapping space between the blades and tines. The tool also has a forked assembly generally central of the cutting blades and flexible tines to stabilize the tool while in use and can till the soil as well. There is also provided a shaft central of the blades, tines, and forked assembly to attach the remainder of the tool to a rotation system such as a hand crank or electric drill.
