Just for fun. A side note on that ----- Standards for ROPS published by these organizations include OSHA 1926.1000, OSHA 1926.1002, OSHA 1928.51, OSHA 1928.52, OSHA 1928.53, ASAE S383.1 and S581, and SAE J1194 and J2194. The OSHA standards are federal regulations and require labeling of each ROPS, while the ASAE and SAE standards are voluntary standards. The OSHA regulations require that all tractors built after October 25, 1976 and used by employees of a farm owner be equipped with ROPS. OSHA, however, does not have jurisdiction to enforce the regulation on farms with fewer than 11 employees.
