BODY OF THE PLOW Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: body of the plow has stand 1, plowshare 3, dumping ground 5, field board 4 and fasteners 2. Grooves 7 are punched on the surface of dumping ground 5 in the direction of the layer movement. Their width increases according to their arrangement from the plowshare upwards with the simultaneous decrease of the distance between them; the volumes of the grooves are filled with antifriction material 9 up to the working surface of the dumping ground. Different characteristics of the layer movement in different portions of the dumping ground create inner stresses tearing the layer. EFFECT: enhanced quality of the soil preparation and lower power consumption. 3 dwg
