Abstract
A harvesting head for an agricultural harvester including a center frame section that is pivotally coupled to each of a left frame section and a right frame section. The elevation or height of the center frame section is determined by setting a height of the inner gauge wheels of the left and right frame sections. A gauge assembly for each of the left and right frame sections includes a linking member that spans between and operatively connects to outer and inner gauge wheels. The gauge assemblies are operably connected to the left and right frame sections to adjust an elevation of the outer and inner gauge wheels relative to the linking member to thereby adjust the elevation or height of the frame section when actuated by an actuation mechanism.
