ABSTRACT:
The system includes a pull-type frame with a forward line of disc blades widely spaced to part the trash, mix it with soil and displace most of the mixture laterally on top of previously undisturbed soil, thereby creating strips of ground which are alternately cleared and windrowed. At least a second line of disc blades, also widely spaced, is placed to the rear of the first line; and these blades are offset laterally from, and located in the windrows formed by, the discs of the first row, to part and return at least some of the previously cleared trash and previously undisturbed soil back onto the cleared strips while still leaving strips of undisturbed soil with an accumulation of cleared trash on top. Following the discs are novel plow tips located in the undisturbed strips having accumulated layers of cleared trash. The plow tips each include a tooth for breaking the soil and wings which twist and turn the broken soil without throwing it to the side, thereby mixing the trash with top soil, evenly distributing the mixed soil and trash, burying a controlled amount of trash, and bringing up some deep soil, all without creating a plow sole or digging up the buried trash.
