Unless the standard has changed since I retired, certification requires a destructive test. The frame is secured in a rigid mount (usually very rigid anchors through a thick concrete floor) and the ROPS is loaded with hydraulic cylinders in the side to side and fore-aft directions. Force applied is based on the maximum machine weight (which should be displayed on the ROPS certification plate). Once the design is certified the ROPS can be built by any shop as long as it meets the print specs and is welded by a certified welder. The steel must also be certified.
One thing - I have never checked an accident where the machine had a ROPS and the a ROPS had failed. I have visited several where the machine was equipped with a ROPS yet the victim was fatally injured. In every case the victim was not wearing a seat belt. Accident reconstruction experts are amazing in how they can determine what happened. I was involved in determining the cause of one such accident. All we had to go by were pictures the police had taken, the coroner's report, and the machine. Police report stated other crew members told them the victim often stepped on the clutch going down long, steep grades in order to get back to the chop quicker. In this case we estimated the machine reached 45 mph (max travel speed 24) when he lost control and was thrown from the machine. Victim died of a broken neck. Accident reconstruction specialist had me pace off the distance from where the machine crashed to where he thought the body landed. Sure enough there on the roadside were a couple covers from heart needles - the long needle syringes that can inject medication directly into the heart. The machine was intact. They had rolled it back upright and drove it off. Victim may have survived if he had been using his belt but at that speed a person can get whipped around pretty bad on a non-cab machine.
Yes, that victim was stupid, but in many of the cases something unexpected happens like a bank gives way or you hit something that blows a tire.
Go to local racetracks and see all garage/hand built roll cages, with most of high quality. Joining multiple round tubes at various angles for high speed protection pretty much makes welding a simple ROPs tube child's play in comparison.
For those of you who think you can do what ever you want "because it only affects yourself" are the most deluded bunch of liars I've heard since the last White House press release. Your wreck , injuries, rescue, investigation, treatment and rehab if you survive are paid out by every other tax payer.
I sure hope my post doesn't incite the wrath of the safety police, but I would like to get a few thoughts on removing the ROPS. Here is my situation; I have a Grand L with FEL that I wouldn't dream of removing the ROPS from. However, I recently acquired a BX2200 strictly for mowing. During routine maintenance this weekend, I even removed the lift arms, and toplink.
I'm finding the ROPS sure hits a lot of limbs mostly on fruit trees, and even creates a situation causing more trim work. Have also lost a number of peaches recently from the ROPS hitting them.
I know the BX is considered a tractor, and is equipped just like it's big brothers, but, on the other hand, it's not much larger than the JD riding mower I have, which did not even come with a ROPS.
In short, I'm thinking of taking it off. Give me a good reason why I shouldn't.

Interesting line of logic. I've heard people use that argument for seat belt laws, motorcycle helmet laws, and other "victimless" crimes, etc..
So by that logic, I assume you would support a law that everybody has to:
1) Brush their teeth 3 times a day. (I mean, gum disease can get serious and " treatment and rehab if you survive are paid out by every other tax payer".)
2) Only eat healthy food. High fat and sugar foods should be outlawed. (Again, obesity diabetes and heart disease are serious killers and "treatment and rehab if you survive are paid out by every other tax payer".)
If not please explain why?
I never read your original post. If it were mine, I'd take off the rops for sure, and store it somewhere. Put it back on if you ever sell it.
Waxman,
I'm sorry something in life made you so fearful.
There's plenty of people like me that live, to live. For example: I live in a state that has no helmet law. According to you, we helmetless bike riders are stupid.
I guess my whole state must be stupid by your opinion.
I spent a large part of my life building and driving race cars. Now that's dangerous and stupid. A smart person wouldn't take such a chance...
"And what about if one of your welds failed after you sold it?" yes...how to sleep at night?
You really need to mature to the point where you can see the difference between stupid and risk taking...the later being, what historically smart people have done, for life's excitement, and for innovation. In fact without risk taking, many of the major technologies we enjoy would never had happen.
Myself and other have pointed out dangers by using ROP's around trees. Maybe someone like me who's not afraid to make change ( unlike you ) will come up with a better device...who knows?
Done.
I went to an auction of logging equipment in WA State to see what I could find.
In the disclosures I found custom modified ROPS
Was not sure what had been done so I asked and found out the two bars from the front of the dozer to the canopy were added as was all the heavy mesh screen on the Deere 350 Dozer I was looking at.
In MY opinion the modifications made the dozer safer for tree work... of course it was a 35 year old machine...
Which begs the question what happens should someone need to repair a ROPS and parts are no longer carried... tractors last a very long time...
I would seem a colossal waste to toss or part out a tractor simply because a manufacturer certified piece of foreign made steel is no longer available...
