7 Tractor Safety Guidelines B. Protective Devices Protective Structures Roll-over protective structures (ROPS) refer to the operator compartment structure, typically a cab or framework intended to protect operators from injuries caused by overturns or rollovers. Seat belts are an integral part of any ROPS and should always be used. All tractors should be equipped with ROPS, and most new tractors are installed with ROPS. However, not all tractor cabs are ROPS, so consult your tractor’s operator’s manual to determine if your cab is a ROPS. If it is not, a ROPS can be installed by a certified farm equipment dealer. Falling object protective structures (FOPS) should be installed (tractors with front end loaders) if there is a risk of the tractor operator being struck by debris.
