Header with trapezoidal profile
A header of an agricultural harvester is provided. The header includes a frame having a centerline defining a first side and a second side of the frame. A first portion of either the first side or the second side of the frame has a first trapezoidal profile that includes a first pair of legs that run along a longitudinal axis of the frame and a first pair of bases that form a height of the frame. The first pair of legs include a first top leg and a first bottom leg, and the first bottom leg is angled toward the longitudinal axis.
