The present invention relates to an agricultural machine for strip cultivation of soil, particularly the agricultural machine for strip cultivation of wide-row plants, comprising a frame (1) with at least two cultivation units (2) for loosening strips of soil, has at least two rolls (3, 4), which are arranged one after the other in the direction of the machine movement after the at least two cultivation units (2). Each roll (3, 4) comprises a plurality of spike-teeth (5, 6) arranged on the circumference thereof in at least one point of its axis. The spike-tooth (5) of the front roll (3) is axially shifted relative to the spike-tooth (6) of the rear roll (4), whereby a circle (7), circumscribed by the front roll (3) spike-tooth (5) during the rotation thereof, overlaps the circle (8), circumscribed by the rear roll (4) spike-tooth (6) during the rotation thereof. The spike-teeth (5) of a common front roll (3) and spike-teeth (6) of a common rear roll (4) are arranged in zones (9) behind the at least two cultivation units (2) with the proviso that the width of each zone (9) is less than 60 percent of the pitch (10) of the adjoining cultivation units (2). |
