Hinge assembly for wing frame sections of agricultural implement

Abstract:

A hinge assembly for an agricultural implement having inner and outer wing frame sections has an inner pivot bracket pivotally coupled to the inner wing frame section at a fold pivot location, and an outer pivot bracket pivotally coupled to the outer wing frame section at a flex pivot location and coupled to the inner pivot bracket. An inner pivot link pivotally couples to the inner pivot bracket and the outer pivot bracket, and an outer pivot link pivotally couples to the outer pivot bracket and the outer wing frame section. The inner and outer pivot brackets pivot relative to each other at the fold pivot location between a working state and a folded state, and the flex pivot location moves relative to the fold pivot location during the relative pivoting. When in the working state, the fold pivot location is higher than a top side of the inner wing frame section and the flex pivot location is lower than a bottom side of the inner wing frame section.
