Abstract:
An implement for supporting a plurality of ground cultivating implements extending transversely along a line substantially perpendicular to a line of working travel comprising:a main section having a main tool bar with first and second ends and having a main longitudinal axis that extends substantially perpendicular to the line of working travel;a first wing section having a first wing tool bar with proximal and distal ends and having a first longitudinal axis that extends substantially perpendicular to the line of working travel wherein the proximal end of the first wing tool bar is coupled to the first end of the main tool bar;a second wing section having a second wing tool bar with proximal and distal ends and having a second longitudinal axis that extends substantially perpendicular to the line of working travel wherein the proximal end of the second wing tool bar is coupled to the second end of the main tool bar;a first flexible coupling through which the proximal end of the first wing tool bar is coupled to the first end of the main tool bar;a second flexible coupling through which the proximal end of the second wing tool bar is coupled to the second end of the main tool bar;wherein the first flexible coupling includes a first pivot bracket extending substantially vertically and having an upper pivot and a lower pivot vertically opposed on the first pivot bracket pivotally coupled to the first end of the main tool bar and the other of the pivots pivotally coupled to the proximal end of the first wing tool bar and;wherein the second flexible coupling includes a second pivot bracket extending substantially vertically and having one of the upper pivot and the lower pivot pivotally coupled to the second end of the main tool bar and the other of the ends pivotally coupled to the proximal end of the second wing tool bar.
