many old iron still in use that have no ROPS.
Just know your machine and you shouldn't need a ROPS. Many safety devices we have today come about from those that have no business operation a tractor,or just doing things they shouldn't be doing.
Back in the day, only farmers had tractors. Now, it seems everyone has a tractor .
Just look at all the safety devices we have in vehicles these days. Some are very good. some are just common sense things.
especially, with TPMS. I guess many can't even check their tire pressures
Keeping your bucket low when carrying loads, Be mindful about being sideways on grades, try to pull difficult things from the front instead of rear.
Using Common sense is safer than any man made device could ever be.
Having said that, I don't know if any of those that built the ROPS for the VN imports are still building them,or not.
If they are, they may have made one for your model
