摘要

A rotary hoe wheel is adapted to be propelled at an angle to the direction of travel and is provided with teeth extending radially from a hub and curved rearwardly with the surface of the ground being first engaged by a curved portion of each tooth between the hub and the outer end thereof. A cross-section of the tooth is disposed in a tilted plane to provide an earth penetrating leading edge and each tooth has a lower convex surface and an upper concave surface forming a scoop to lift and turn the soil.
