Triple-fold agricultural implement with narrow and low transport profile

摘要

A triple-fold agricultural implement includes a center frame section, and a plurality of wing sections positioned on opposite lateral sides of the center frame section. The plurality of wing sections include an inner wing section, a middle wing section and an outer wing section. Each outer wing section may be folded approximately 180° laterally inward and over a respective middle wing section. Each middle wing section may be folded approximately 180° laterally inward and over a respective inner wing section. Each inner wing section may be folded approximately 90° laterally inward and over the center frame section, whereby each of the plurality of wing sections when in a folded state are in a transport position lying above the center frame section.

1. A triple-fold agricultural implement, comprising:
a center frame section; and a plurality of wing sections positioned on opposite lateral sides of the center frame section, said plurality of wing sections including an inner wing section, a middle wing section and an outer wing section, each said outer wing section being configured to fold approximately 180° laterally inward and over a respective said middle wing section, each said middle wing section being configured to fold approximately 180° laterally inward and over a respective said inner wing section, and each said inner wing section being configured to fold approximately 90° laterally inward and over said center frame section, whereby each of said plurality of wing sections when in a folded state are in a transport position lying above said center frame section, wherein each of said plurality of wing sections has a vertically offset pivot axis allowing said outer wing sections, said middle wing sections and an inner wing sections to stack together in a horizontally arranged stack over the center frame section when in the folded state, wherein each said middle wing section has a pivot axis that is vertically higher than a pivot axis of an adjacent said outer wing section or inner wing section, when in a unfolded state.
