The American Society of Agricultural and Biological Engineers (ASABE) announced that the international community has approved a new International Organization for Standardization (ISO) standard for determining the center of gravity and stability of self-propelled, ride-on agricultural machine.

The new document, ISO 16231-2, Self-propelled agricultural machinery – Assessment of stability – Part 2: Determination of static stability and test procedures, will help prevent rollover accidents.

A variety of factors affect the operation of self-propelled, ride-on machinery, including axle movement, the topography of the land, and whether or not the machinery is carrying or towing a load. This standard assists in determining the safest design configurations for a variety of conditions and provides calculations to determine the center of gravity and best rollover safety limits.

ASABE is accredited by the American National Standards Institute as the administrator for the U.S. technical advisory group to the ISO subcommittee for operator comfort on Tractors and machinery for agriculture and forestry, ISO TC 23 SC 3. Individuals, companies, or organizations interested in joining the committee or wishing additional details regarding ISO 16230-1 may contact Scott Cedarquist at ASABE,
