Abstract
A low profile discharge gate assembly including a rigid frame defining a generally rectangular discharge opening and a gate slidably mounted on the frame for controlling discharge of commodity from the gate assembly. Structure carried by and extending inwardly from the frame is arranged between a lower surface on the gate and boot flanges defined by the gate assembly frame for restricting the flow of commodity from the gate assembly. A vertical distance of less than 7.5 inches separates the boot flanges from mounting flanges on the gate assembly frame whereby permitting a conventional unloading sled to fit under the gate assembly to discharge commodity therefrom. An operating shaft assembly selectively controls movement of the gate between open and closed positions. A lock assembly is also provided for inhibiting inadvertent movement of the gate from the closed position toward the open position.
