ABSTRACT:
A reversible plough, that in one embodiment is of the semi-mounted type, and comprises a main beam, a coupling structure at the forward end of the main beam, and a carrying beam. Pairs of plough bodies are mounted along the length of the carrying beam. The carrying beam is pivotably connected to the main beam to move between a first and a second ploughing position for plough body reversal. The reversible plough further includes a coupling beam that is secured to the carrying beam, and a soil preparation device such as a packer that prepares the soil turned over by the plough bodies for seed. The coupling beam projects laterally from the coupling beam in either ploughing position and is moveable with the carrying beam during plough body reversal. A hopper is mounted at a fixed location relative to the packer and the reversible plough combination, and a distributor is mounted on the packer and arranged to distribute the hopper content onto the ground. The hopper contents are conveyed by a flexible distribution system that includes a line extending between the hopper and the distributor.
