ABSTRACT:
A rotary plough has one or more rotors rotatably mounted to be driven via a power take off about a horizontal axis that extends transverse to the direction of travel. Each rotor has a central support and axis of rotation and two spaced apart and oppositely positioned rotatable soil working members, each of which has a soil working support with two rows of tines. A driving connection is established between a P. T. O. and a shaft within the central support which turns each soil working member through a control mechanism. The control mechanism can be a pinion gear arrangement or a chain and sproket combination that turns the tine supports of the soil working members so that a transmission ratio is established to cause the tines to rotate more or less about their supports while also turning about the central support. Earth lumps are cut and lifted by the tines and then moved to an inverted position back to the dug out cavity. An adjusting lever is attached to turn the shaft relative to the central support which also varies the relative positions of the rows of tines and changes their angle of soil penetration. Two rotors can be provided each with two soil working members and the four members can be spaced 90.degree. apart around the central support.
