A crop harvesting header includes a sickle knife driven by a first hydraulic motor and a crop transfer system including three conveying drapers which is driven by at least one second hydraulic motor. A mechanical drive input from the combine harvester drives a first pressure regulated piston pump generating flow for the first motor and a second gear pump for the second motor. When the drive input is driven in the reverse direction, hydraulic fluid is supplied from the second pump in the reverse direction for driving the second motor in the reverse direction. As the first pump does not pump in the reverse direction the hydraulic control circuit is arranged such that, when the second pump is driven by the drive input in the reverse direction, hydraulic fluid is supplied from the second pump to the first motor for driving the first motor in the reverse direction.
