Purpose and Scope

This Standard is intended to provide the basic requirements for a uniform procedure for measuring and reporting combine capacity, as defined in American National Standard ANSI/ASAE S343, Terminology for Combines and Grain Harvesting. Because crop conditions are variable and uncontrollable, the procedure provides only for the comparative testing of one combine, or one combine configuration, relative to another, in a particular crop condition.

In addition to measuring and reporting combine capacity, this Standard is also intended to provide the basic requirements for evaluating the uniformity of material spread from harvest residue spreading or chopping device(s). Harvest residue spreaders may be evaluated for spreading either straw or chaff separately or as a system for spreading both together.
