ABSTRACT:
In an attachment combination for agricultural tractors used for loosening soil in a field covered with living or dead plants or crop residue, a covering hood forms an ejection channel with a motor driven flail mower positioned under the hood. A support tube is located behind the mower and it carries at least one row of loosening elements. Motor driven rotatable tools are located rearwardly of the loosening elements. The flail mower hood can discharge in a first position where the material is directed downwardly and rearwardly in front of the support tube or in a second position where the material is directed behind the loosening elements and the rotatable tools. The mower is mounted on a rearwardly open U-shaped support frame consisting of a cross beam and two laterally spaced longitudinal beams extending perpendicularly of the cross beam. A coupling piece is located on the free end of each longitudinal beam with a counterpiece clamped on the support tube. The coupling pieces can be easily detached from the counterpieces.
