There are two types of rollover protective structures:
Rollover Protective Frame
Rollover Protective Enclosure
Rollover Protective Frame
These are either two or four post frames which are securely mounted to the main
body of the tractor.
Use the provided seat belt to keep the operator within the protected area.
Rollover Protective Enclosure
A rollover protective enclosure utilizes the protective frame, but totally encloses the frame with metal
and glass. Seat belts are provided and must be used to contain the operator within the protected area.
In addition, this cab enclosure gives protection from weather, dust, noise and vibration.
Enclosures on older tractors were designed for operator comfort not
for rollover protection and they are not considered ROPS. ROPS must
meet regulations and standards that certify that they provide adequate
protection in a tractor rollover. To find out if a frame or enclosure is
certified, look for a certification label, contact the manufacturer, or
check for the presence of a manufacturer installed seatbelt.
Reducing the risk of a side rollover:
Set wheels as far apart as possible.
Lock the brake pedals together before high speed road travel.
Match speed to operating conditions and loads. Do not let the front
wheels bounce.
Slow down before turning.
Use engine braking when going downhill.
Avoid crossing steep slopes. Watch for depressions on the downhill
side and bumps on the uphill side. Turn downhill, not uphill, if stability
becomes a problem.
Stay at least as far from ditches and rivers as banks are deep.
