Agricultural soil aeration machine for use during prairie regeneration work, has left and right flanges comprising angular adjustment device for angularly adjusting rotors in plane parallel to work land

摘要

The machine has a tubular chassis (A) with a rectangular frame (3) reinforced by two crosspieces (4) at the proximity of a base of a three point linkage device (1). Central, left and right flanges (6, 7, 5) are welded on the frame. The flanges (5, 7) have an angular adjustment device (11) for angularly adjusting two rotors (10) in a plane parallel to a work land. The amplitude of the angular adjustment is around 10 degrees.
