Abstract
A plough having a landslide and tilling mechanism, illustrated as a rotary disc or soil inversion wheel, which is pivotable in relation to the landslide between alternative positions providing for the left-hand or right-hand formation of a furrow, depending upon the direction of ploughing, when the plough is required to operate back and forth across a field.
Claims7
A plough comprising a stabilising means, for maintaining direction of movement of the plough relative to a ploughing direction during ploughing, a soil tilling means which comprises a rotatable tilling member and which is pivotally movable relative to the stabilising means between first and second positions on opposite sides of the ploughing direction such that in the first position the tilling means is operative to displace soil in one direction away from the ploughing direction and in the second position is operative to displace soil in a direction opposite to said one direction and away from the ploughing direction, and a pointed member fixed relative to the stabilising means and provided forwardly of the tilling member in a ploughing direction, the stabilising means comprising a fixed landslide for maintaining the position of the plough during ploughing by engaging the side of a furrow formed by the pointed member and the rotatable tilling member regardless of the direction of ploughing.
