Coal, and the like, contained in a truck is sampled by initially removing a core sample from the load, crushing the sample, dividing out an unwanted portion of the crushed sample, and returning the unwanted portion back to the load while the sample portion is delivered to a predetermined receptacle associated with a vender of the coal or other material forming the load. An auger mounted for reciprocation in a substantially vertical path and having a cutting head at the lower end is provided for cutting through the lumps of coal in order to obtain a representative sample.
