1 Purpose and Scope

The purpose of this Standard is to establish the test and performance requirements of a roll-over protective structure, ROPS, designed for compact utility tractors to minimize the frequency and severity of crushing injury to the operator resulting from accidental tractor upset.

This Standard applies to compact utility tractors as defined in 3.1. It does not preclude the use of extendable or foldable ROPS as long as these ROPS meet the performance requirements of this Standard. Self-propelled implements are excluded. This Standard does not apply to tractors with mass as defined in 3.3 greater than 1800 kg.

Test procedures in this standard are limited to compact utility tractors. This Standard does not apply to tractors generally designed for mowing lawns and gardening work as defined in ASAE S323.
