A versatile cultivator is provided wherein to a transmission mechanism for transmitting the power of an engine to a cultivating mechanism is operatively connected a power take-off shaft which projects from a lower front portion of a transmission housing accommodating therein the transmission mechanism, and wherein a running wheel unit is removably attached to the lower front portion of the transmission housing, the wheel unit having running wheels rotatably mounted on lateral sides of the front end thereof while being provided with an interlocking mechanism for linking the running wheels to the power take-off shaft. The cultivator can either be used as a rototiller or as a rotary cultivator, simply by mounting or dismounting the running wheel unit.
