Flexible multi-section implement

Claim 1

An implement frame construction comprising: a. left rigid horizontal frame section and a right rigid horizontal frame section positioned in generally side-by-side relation, tillage tools depending from said frame sections, said frame sections respectively including inner and outer elongated longitudinal structural beams and front and rear elongated transverse beams welded together and forming front and rear inner and outer frame section corners; b. vertically adjustable wheels mounted on said respective frame sections and supporting same for forward horizontal movement along the ground; c. an elongated forwardly and inwardly angled draw tongue for each of said frame sections, pivotal joint members connecting the rear ends of said draw tongues to said respective front transverse beams and permitting said draw tongues to pivot vertically, a tractor hitch clevis flexibly connected to the front ends of said draw tongues and forming a common generally central draw point for said frame sections; d. a front transverse spacer link having ball joints at opposite ends, said last named ball joints being connected respectively to said draw tongues intermediate said tongue ends, an elongated rear transverse stabilizing bar having opposite ends and extending generally parallel to said rear transverse beams, said rear bar ends being vertically pivotally connected to said frame sections near said respective rear outer corners; e. a gag link having an upper end and a lower end and a central mount therebetween, said gag link being positioned generally between said frame sections and pivotally engaged at said central mount with one of said inner beams intermediate said front and rear inner corners, a first gag having a forward end pivotally connected to the other of said inner beams near said front inner corner, said first gag bar having a rear end pivotally connected to one of said gag link ends, a second gag bar having a rear end pivotally connected to said other inner beam near said rear inner corner, said second gag bar having a front end pivotally connected to the other of said gag link ends; f. whereby said frame sections are permitted to universally flex with respect to each other without substantial variation in lateral spacing therebetween.
