15、s intended to guide the manufacturer who wishes to supply an instructional seat and restraint inside the enclosed cab of an agricultural tractor. Nevertheless, many types of agricultural tractors will not be able to accommodate this feature.This International Standard is recognition that an instruct

17、o persons one seated in the operators seat with restraint and the other, a trainer, trainee or service person, seated in the instructional seat with restraint provide greater safety for both persons in a rollover than would be available without an instructional seat.
