Abstract
A draper header for a combine, the draper header including an attachment frame adapted for attachment to the combine. A harvesting assembly includes a plurality of sections and a plurality of belts operable to feed crop material into the combine. The draper header is operable in a first mode that allows the plurality of sections to float relative to the attachment frame for ground following during harvesting, and in a second mode in which the attachment frame is raised to lift and support the harvesting assembly to be spaced above the ground. A hydraulic leveling system includes at least one leveling actuator. A valve is operable in response to the movement of the draper header into the second mode to direct pressurized hydraulic fluid into the at least one leveling actuator to automatically level the plurality of sections of the harvesting assembly when in the second mode.
