A header support for supporting a header during road transport of an agricultural harvester. The header support has a header mounted to it in order to reduce a front axle load of the agricultural harvester. During harvesting, a support wheel of the header support is folded upwardly so it does not touch the ground during harvesting. The rotation axis of the support wheel extends in a substantially vertical plane during harvesting. This allows for a simple construction of the header support and reduces the vibration loads on the bearing of the support wheel during harvesting.
