Whats so special about a ROPS? Why can't I build my own?

ROPS are designed and engineered to comply with SAE, ASAE, ISO and Federal Standards. A ROPS is engineered to mount on a specific tractor model. It is designed to work in conjunction with the tractor's mounting brackets and main frame. This provides a structure that is not too stiff, but at the same time strong enough to withstand the loads generated during a rollover event. The use of sophisticated computer software, coupled with engineering experience and Real World Performance Testing results in a ROPS that will provide the intended safety to the tractor user.

What does Real World Performance Testing do?

This physical performance testing is done on each new ROPS design. Once a ROPS has been designed and engineered, a prototype is manufactured and mounted to the intended tractor or tractor's main frame. Once the tractor and ROPS have been joined, they are tested to SAE and ISO performance standards. This simulates the event of a tractor rollover. This testing provides confirmation of the design. Only after this is complete, can the ROPS be sold for use by the industry.

Why is it necessary to wear a seatbelt?

In the event of a rollover, the use of a seatbelt keeps the machine operator within the critical zone of protection created by the ROPS. Without the seatbelt, the operator might be thrown from and crushed by the tractor. Rops are only fully effective when used with a seatbelt. Seatbelts are now being offered on off-highway equipment with retractors and with anti-cinch devices to add to operator ease of use and comfort.

Can I modify my ROPS to add aftermarket attachments or reduce the height by shortening the legs?

Any unauthorized modification to a ROPS is inappropriate. ROPS manufacturers in most cases, will void the certification supplied with a ROPS if the ROPS has been drilled, welded, cut upon or modified without proper modification. ROPS are designed, engineered and tested to perform a specific task....to save human life. Unauthorized modification can impair the ROPS ability to perform properly in the event of a rollover. Contact your local equipment dealer or the ROPS manufacturer before making any modifications to a ROPS.

My tractor rolled over. My ROPS looks to be in good shape. Do I need to replace my ROPS now?

Yes. A ROPS is designed and engineered to provide protection for a single rollover. During a rollover a ROPS is subjected to the impact of the event. The structure has done it's job and must be replaced. Even though a ROPS may look undamaged after a machine upset, there is no way to know if the structure is cracked or damaged in such a way that will cause it to fail during a second rollover.

Are ROPS mounted with a special type of fastener?

Yes. ROPS are commonly mounted using Grade 8 Imperial and Grade 10.9 Metric sized fasteners. If a ROPS is removed and is remounted, this type of fastener must be used during reinstallation and proper bolt torque must be applied. Standard Grade 5 fasteners are not adequate for a ROPS application. Check the maufacturers installation instructions for a list of materials and proper procedures.

Is it necessary to inspect or service my ROPS?

Yes. ROPS should be inspected periodically to check for excessive rust, cracks, or other signs of wear. Additionally, rubber isolation mounts incorporated into a ROPS should be inspected periodically for possible deterioration. Any of these may cause a failure of the ROPS, if they are not addressed. If any sign of wear and tear is identified on a ROPS the manufacturer should be consulted to determine the proper course of action.

Some additions to the answers given:

Q: Why is it necessary to wear a seatbelt?

A: ... Installing a ROP's and not wearing the seatbelt can actually increase the chance of injury in a roll-over in some situations compared to a machine without a ROP's. The ROP's structure can impede falling or jumping clear of the rolling machine, and is one more sturdy object to cause injury to the operator should it strike or land on them.


Q: My tractor rolled over. My ROPS looks to be in good shape. Do I need to replace my ROPS now?

A: ... Damage could extend to more than just the ROPs structure itself. There could be damage to the axle or transmission housings (typically castings) where the ROPs is attached. In addition to considering replacement of the ROPs, the tractor should be professionally inspected for any damage to the ROPs mounting points.


Q: Can I modify my ROPS to add aftermarket attachments or reduce the height by shortening the legs?

A: ... Even modifications that do not involve drilling, cutting, or welding can reduce the safety effectiveness of the ROPs. For example, lights or other accessories clamped to the interior of ROPs can reduce size of the safety zone - one more thing to crush or strike the operator in a roll over.

Even minor things like protruding bolt ends on a clamp can cause injuries.


Q: What does Real World Performance Testing do?

A: ... These real-world performance tests are often carried out to the point of destruction or failure on sacrificial prototypes of the design so as to ascertain the ultimate failure point of the system. These prototypes (perhaps including the entire tractor) are discarded after the completion of testing. Unless one is prepared for the expense of building one or more sacrificial prototypes to be tested to destruction and discarded, it is not feasible to fully verify modifications and customizations of your ROPs with real world performance testing.


Additionally:

Q: Can I use the ROPs as an anchor point to get "upward" leverage or increased down-force for traction when pulling things with my tractor?

A: Using the ROPs or any other point forward and/or above the rear axle as an anchor point for towing or pulling is very dangerous as it leads very easily to back-flips.
