Abstract:
An in-line sub-surface seeding, fertilizing and watering device comprising an in-line blade mounted to a header member of a parallelogram linkage so as to be vertically downwardly disposed generally in a plane containing said linkage, said blade having internal conduits for transporting seed, fertilizer or water from an upper infeed to openings at a lower end of said blade, said parallelogram linkage comprising a pair of parallel rigid drag arms extending between said header member and a hanger member, said arms pinned at their respective ends to said header and hanger members so that rotation of said header member relative to said hanger member on said parallel arms maintains a generally horizontal orientation of said header member thereby supporting said blade, when mounted in said header member, downwardly in a constant orientation, wherein said hanger member is mountable to a supporting frame, said device further comprising selective actuation means for selective control of a downward force urging said blade, when on said header member, downwardly into soil.
