  • Positive open grain saving unloading system
    Patent number: 8265837
    Abstract: An unloading system for an agricultural harvesting machine for reducing grain loss by detaining a grain saver door after movement to a fully open position during the unloading process, and by rapidly returning the door to a closed position with sufficient force for urging grain in the door area back into an unloading tube a predetermined time after the unloading process pauses or ceases. The system can advantageously detain the door in the open position in the presence of varying or reduced amounts of grain for increasing consistency and cohesiveness in the flow discharging grain and reduce the amount of grain remaining near a discharge end of the unloading tube when the door is in the closed position.
