US Patent 9144188 Autonomous self-actuated tillage implement

An implement has at least a first plow share in front, provided with an anti-rollback mechanism, and at least a second plow share in the rear, with another anti-rollback mechanism. The plow shares are interconnected by alternate approaching and distancing mechanisms. A telematic control unit based on a computer system that is assisted by a global positioning system, autonomously guides movement of the implement. A steering system formed by an oscillating support can rotate in a plane perpendicular to the advancement direction of the implement and lifts one of the plow shares in relation to the ground and moves it laterally. A power supply system using renewable energy or internal or external combustion engines is mounted on the implement.
