This SAE Standard applies to an overhead cover installed on a protective frame or enclosure conforming to SAE J2194 or alternately SAE J1194 and the following additional requirement of a drop test to verify the effectiveness of the overhead cover in protecting the operator from falling objects. The test procedures and performance requirements outlined in this document are based on currently available engineering data. This document establishes test and performance requirements for overhead protection to minimize the frequency and severity of operator injury due to falling objects encounted in normal operation of a wheeled agricultural tractor.
