A harvesting machine is provided for harvesting a crop and discharging the harvested crop to an offboard container, such as a wagon or a truck, or the ground. The harvesting machine includes a power system to provide power, a crop harvester powered by the power system, and a crop discharging system to discharge crop from an onboard storage container to the offboard location, typically a container. During a harvesting operation, the harvesting machine operates at a nominal maximum power, typically a current power consumption. The nominal maximum power is reduced in anticipation of a predicted power used for discharging the harvested crop from the onboard storage container. The current power consumption for harvesting is adjusted and allocated by the predicted power to make available power for the crop discharging system. Once crop is discharged using the discharging power, the harvesting machine returns to the nominal maximum power.
