  • Plow apparatus and method using acoustics
    Patent number: 5271470
    Abstract: The plow apparatus has plow blades to break up the soil in the plowed field. The broken up soil is scooped up with scooper blades by the forward motion of the plow apparatus and then conveyed to rotating tillers. The tillers break up the soil into smaller clumps. The tilled soil is then exposed to acoustical energy provided by acoustical transducers. The acoustical energy is of a sufficiently high intensity so as to kill or destroy weed seeds and insect larvae in the soil. The soil is then returned to the ground.
