Grain for testing is placed in the hopper. When the gate is opened, grain drops into the kettle, fills it and flows over the sides. The operator strikes off the top of the kettle with a leveling stick and weighs it. Weight
of grain in the kettle is measured in pounds and this value is multiplied by 32 (the number of quarts in a volume or Winchester
bushel) to obtain the grain test weight in units of pounds per bushel.
