US Patent 10278330 Combine feeder house gauge wheels

A combine has a feeder house extending forward from the front of the combine, with the front of the feeder house defining a rectangular frame for supporting a harvesting head. A gauge wheel arrangement is supported on the rectangular frame and in turn supports the harvesting head. The gauge wheel arrangement includes a center frame that abuts the rectangular frame and pivots with respect to it. A left side frame with gauge wheels is hinged to the center frame. A right side frame with gauge wheels is hinged to the center frame. The center, left, and right frames can support the harvesting head and permit the harvesting head to pivot with respect to the feeder house, as well as supporting a part of the weight of the harvesting head on the gauge wheels.
