Furrow Slice Retainer Patents (Class 172/757)
  • Patent number: 5063999
    Abstract: A moldboard plow apparatus having alternate and cooperating moldboards or so-called "scoops". The first of the moldboards digs out and lifts a first soil section from a ground surface thereby forming a first furrow or so-called "cut". The second moldboard or so-called "scoop" cuts and lifts a second soil section thereby forming a second furrow, parallel to and usually adjacent to the first furrow. The moldboards are shaped such that a rearward movement of the soil sections on the respective moldboards causes the soil sections to be inverted and thrown from the moldboards into the opposite furrow in an upside-down condition. Thus the first soil section is thrown into the section furrow and the second soil section is thrown into the first furrow.
