  • Publication number: 20150373897
    Abstract: The disclosed single pass raised bed preparation system makes use of one or more rows of adjustable height compact discs (4), to mulch up stubble and loosen the soil in the depressed furrows prior to the action of a bed-forming implement (6) mounted behind the discs. At the same time the raised beds are cultivated by two rows of compact discs, with the second row (2) opposite handed to the leading row (1). A roller or crumbler (7) levels and conditions the beds, so that both the beds and the furrows are restored in a single pass to a condition ready for sowing.
