ABSTRACT OF THE DISCLOSURE A novel method and apparatus is provided for testing the moisture content of grain. The invention is predicated on the discovery that the friction between one grain and another grain and/or a solid surface is a function of the moisture content of the grain. Thus the method is now provided for determining the moisture content of grain comprising the steps of: a) sub- stantially filling a cylindrical cup with the grain; (b) placing a hollow cone whose largest diameter is substantially the same as the diameter of the cylindrical cup, atop the grain; (c) applying a force on the apex of the hollow cone to a maximum predetermined amount to urge the cone into the grain; and (d) measuring the height to which the grain has risen within the hollow cone; the height of grain within the hollow cone being related to the moisture content of the wheat.
