“Rollover Protective Structures”. They are a bar, frame or cab that creates a protective zone around the operator. They virtually eliminate tractor rollover fatalities when used properly.
These are ROPS
The space surrounding an operator’s body. ROPS and a seatbelt keeps the operator within this safe space in the event of a rollover.
This is the Protective Zone
If your tractor does nothave ROPS:
Consult an authorized dealership or the manufacturer to purchase and install ROPS.
Make and install ROPS yourself.
You should not make and install ROPS yourself because:
Tractors that roll over without ROPS =
75% chance of operator death
In 76 fatal rollover cases studied =
All 76 victims were operating tractor without ROPS and seatbelts.
Because you DON’T want this to happen:
Tractor roll over fatalities in Washington State:

2009 - 2006 - none

2004 – 2
2003 – 1
Rollovers happen when the center of gravity passes over the baseline of stability, either to the side or the rear of the machine.
The center of gravity must be kept within the baseline of stability to keep the tractor right side up.
With ROPS, the tractor often rolls just 90 degrees, keeping the operator in a safe zone.
ROPS, and a seatbelt prevents the operator from being thrown off the tractor and being crushed by the tractor, or being thrown into the ground or into surrounding objects.
You must wear the seatbelt or ROPS are worthless. Tighten the seatbelt sufficiently, so you stay in the protective zone. Wear the seatbelt always, even on flat ground.
The next two slides show a tractor with ROPS in a side rollover.
Front wheels catch the depressions and start the roll
With ROPS and seatbelt, operator has an excellent chance of surviving a side rollover.
When the tractor is driven on a hillside that is too steep.
When a tractor with an attachment is elevated too high for a given load, driven on a hillside that is too steep, or is turned at excessive speed.
When the tractor is driven too close to the edge of the road, a ditch, or other steep slope.
Just in case you think you might consider skipping using the seatbelt, look at the next slide and see what can happen.
Even though this tractor had ROPS, the seatbelt was not used, causing the operator to be ejected from the protective zone.
With ROPS and seatbelt, operator has an excellent chance of being contained in the protective zone and surviving a rear rollover.
The ROPS may also prevent the tractor from completely rolling over backward
Five situations causing rear rollovers:
To Prevent Side Rollovers:
To Prevent Side Rollovers:(Con’t.)
To Prevent Rear Rollovers:
The operator must be aware of the ever-changing environment and be able to react accordingly.
For examples, operators must know:
If your tractor does not have a ROPS:
