Abstract
A draper header for a harvester useful for providing hydraulic lifting and lowering of ground wheels. Hydraulic cylinders are capable of being actuated to independently lower and raise the ground wheels of the header while using the floatation pressure from the lift cylinders of the harvester. First and second hydraulic cylinders are fluidically coupled to a charge pressure of the harvester, the charge pressure providing a floatation pressure to position first and second ground wheels at a lowered operation mode and a raised operation mode.
