GRAIN LEVEL INDICATOR The grain level device is generally located within the bin adjacent the upper end thereof and includes a paddle on a swing arm which hangs vertically within the bin from a bracket extending from the bin wall. The swing arm is connected to a plunger slideable within a sleeve extending through the wall. As the grain filling the bin displaces the paddle, the plunger becomes visible through the end of the sleeve externally of the bin.
