摘要：
Embodiments of the present invention provide systems and methods for tilling ground material. According to one embodiment, a tiller system is provided comprising two coiled conical blades that penetrate ground material to provide both forward propulsion and tillage of the ground material. An operator of the tiller system can adjust the angle at which the coiled conical blades penetrate the ground material to achieve an optimal balance of forward propulsion, stability, and tillage of the ground material.
