    • 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.
    • 旋转花园工具具有用于大致水平切割的切割刀片,通常以闭合回路构造设置,在两侧切削,在沿逆时针方向顺时针旋转的同时切割。 柔性齿设计成在旋转期间向外从切割刀片向外弯曲,从而在刀片和尖齿之间产生捕获空间。 该工具还具有叉形组件,通常是切割刀片的中心和柔性尖齿,以在使用中稳定工具,并且也可以直到土壤。 还提供了叶片,叉形和叉形组件的轴中心,以将工具的其余部分附接到诸如手动曲柄或电钻的旋转系统。
