The rationale for moving SAE J 873 to a Noncurrent status is that we are not aware that this standard is being used in industry today and no experts exist to maintain this document.

This SAE Standard establishes a test method to measure drag force of self- propelled, as well as towed, construction, forestry, and industrial machines, with or without payload, as listed in SAE J/ISO 6165 and SAE J 1116.

Drag force is measured as a function of travel speed.
