Floating rod weeder

In combination with an implement including at least one gang section having a plurality of laterally spaced tool shanks dependingly supported therefrom, a floating rod weeder assembly including an upstanding housing having upper and lower ends, first support means supporting said upper and lower ends of said housing behind a first of said tool shanks for limited vertical shifting relative to said first shank, powered output shaft means journaled from the lower end of said housing for rotation about a horizontal axis extending transversly of said gang section, a rod weeder shaft having one end supported from and driven by said powered output shaft, and a plurality of journal means mounted on said rod weeder shaft and spaced apart axially therealong and from said powered output shaft, a plurality of second support means supporting said journal means rearwardly of and from a corresponding tool shank of the other tool shanks for limited vertical shifting relative to said second shank, said first support means including a forwardly projecting first mounting portion stationarily supported from the lower end of said housing and a rearwardly projecting second mounting portion stationarily supported from the lower end of said first shank, said second support means including third stationary mounting portions projecting forwardly from said journal means and fourth stationary mounting portions projecting rearwardly from the lower ends of said other tool shanks, said first and second support means further including elongated horizontal first and second links, respectively, extending between and pivotally anchored at their opposite ends to said first and second mounting portions and said third and fourth mounting portions, respectively, for angular displacement relative thereto about horizontal transverse axes, said first and second mounting portions and said third and fourth mounting portions including coacting portions engageable with each other to limit up and down vertical shifting of said first and third mounting portions and said second and fourth mounting portions relative to each other.
