Abstract
A grain cart is provided having a storage hopper for holding crop material, load cells positioned on the grain cart to measure a weight of crop material in the grain cart and an indicator connected to the load cells. The indicator can be operative to receive signals from the load cells indicating the weight measured by the load cells and to send an electrical signal on an output connection in response to a predetermined weight of crop material being removed from the grain cart. The output connection can be electrically connected to a close gate conductor wire that is operatively connected to the gate actuator, so an electrical signal generated by the indicator on the output connection of the indicator causes the gate actuator to close gates in the storage hopper stopping crop material from being discharged from the storage hopper.
