ASABE to Withdraw Roll-Over Standard

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in 1996, no longer aligns with current equipment requirements and contains references and definitions that are out of date.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 an international scientific and educational organization dedicated to the advancement of engineering applicable to agricultural, food, and biological systems.
