An unloading system (100) for a combine harvester comprises a belt-driven unloading auger assembly (12) and a spill saver door (50) mounted proximate to a discharge end (22) of the unloading auger assembly. Engagement of the belt drive is controlled by a first hydraulic cylinder (46). Opening of the spill saver door is controlled by a second hydraulic actuator (56). The first and second hydraulic cylinders are hydraulically connected in parallel.
