ST JOSEPH, Mich. — The American Society of Agricultural and Biological Engineers (ASABE) has begun the process of withdrawing ANSI/ASAE S478.1, Roll-Over Protective Structures (ROPS) for Compact Utility Tractors.
The standard, first published in 1996, no longer aligns with current equipment requirements and contains references and definitions that are out of date. In addition, adequate ROPS requirements for small and narrow tractors can now be found in several international standards:
- ISO 5700:2013, Tractors for agriculture and forestry — Roll-over protective structures — Static test method and acceptance conditions
- ISO 12003-1:2021, Tractors for agriculture and forestry — Roll-over protective structures on narrow tractors — Part 1: Front-mounted ROPS
- ISO 12003-2:2021, Tractors for agriculture and forestry — Roll-over protective structures on narrow tractors — Part 2: Rear-mounted ROPS
ASABE is recognized worldwide as a standards developing organization for food, agricultural, and biological systems, with more than 280 standards currently in publication. Conformance to ASABE standards is voluntary, except where required by state, provincial, or other governmental requirements, and the documents are developed by consensus in accordance with procedures approved by the American National Standards Institute. For information on this or any other ASABE standard, contact Scott Cedarquist at 269-932-7031, cedarq@asabe.org. A current listing of all ASABE standards projects can be found on the ASABE web site at www.asabe.org/projects.
