ABSTRACT:
An improved minesweeper having a two-sided frame adapted to be coupled to and pushed by a tractor and a rake pivoted from each side of the frame by respective pairs of coupling bars of different lengths so that as the rake moves away from the frame to bury itself in the soil, the coupling bars rotate it to a less aggressive digging angle that prevents the rake from stalling the tractor, wherein the improvement comprises apparatus connected to the frame for catching and sifting mines, soil, rocks and other objects buried in the soil passing over the rake without small amounts of vegetation and variances in soil conditions clogging the catching and sifting means.
