Abstract
A handle-guided, walking type, power-operated rotor tiller, having blades for digging a path in crusted soil while propelling itself along a path is provided with a plow, mounted in rear of the rotor blades to follow in the cultivated path with minimum resistance to advance of the tiller. The plow faces rearwardly and has an upstanding, trailing, plowing edge, and an upstanding trailing plowing surface, obliqued to the path of the tiller, to plow a furrow only when the tiller moves reversely along it's path.
