<p>The invention relates to a machine for working the soil, such as disc tiller, of the type comprising at least one frame (2) equipped with agricultural tools formed by at least two successive rows of discs (5), respectively termed front (3) and rear (4) rows, extending transversely to the longitudinal axis of the frame (2), taken in the direction of movement of said frame (2), each row (3, 4) of discs being formed by discs (5) mounted individually, or in a group, generally by two to five independent discs which oscillate with respect to the frame (2), so as to yield under a predetermined, preferably adjustable, pressure (5) and obtain ground working with a constant depth of the discs (5), the discs (5) of each row (3, 4) of discs working in the soil to a variable furrowing depth by means of at least one reference element (7), such as a wheel, runner or roller, coupled to said frame (2). This machine is characterized in that the discs (5) of at least one (3) of the rows (3, 4) of discs (5) have a diameter which differs from that of the discs of at least one other row of discs (5).</p> |
