A method for using mechanical probes to sample trucks and wagons was developed. The plan involves the collection of multiple samples, with none taken from the center or corners of loads. In tests at a country elevator, the plan yielded accurate corn and soybean samples relative to the pelican method and reduced variability by 15 to 25% in Official Grade factors.
