Abstract
Abstract There is disclosed a tiltable roll protective frame and cab arrangement for tractors and other earthworking and similar vehicles. The arrangement provides a structural frame extending over the operator station of a tractor to protect the operator in case the vehicle should roll over. The protective frame structure includes structural members which also function to support the seat. The arrangement is also constructed so that the seat structure and floor platform serve to enclose the area over controls and other machinery below the operator station. With this arrangement, tilting of the roll structure and cab provides easy access for repair and maintenance of the elements and control means below the operator station. Enclosure panels are provided which are suspended from the roof of the protective frame to provide an enclosure for environmental protection of the vehicle operator.
