8n roll bar

I have looked at ROPS on urban construction and golf course tractors around here -- mandatory for many jobs covered by insurance. Aside from factory-equipped canopies, these are two-post assemblies, usually with a mesh screen between the posts adding protection for the operator from missiles ejected by a bush hog (very worthwhile idea) or to keep you from falling in between the tractor and the implement (even better idea). They do not look like something designed by Daimler Benz. The options for connecting the device to the rear axle are pretty limited.

I think that if you use enough pipe, the device should easily stand up to a sideways roll. However, as someone on this BB recently noted, I wonder if any two-poster would do the job against a back-flip, which the literature says may be a more serious danger. I think that would require an additional post forward, bolted on around the transmission housing. (My 8N does not seem to offer an obvious place to do this.)

I have thought it would just as easy to have one fabricated as to order one from a dealer. Of course, my widow would have no one to whom to take to court if the homemade one fails, but then she would own the tractor and could install a factory model herself.

Design difference wise, the 4 post system does better then the two post system by virtue of a larger protective envelope. It's the difference of a roll bar to a roll cage, and is why Nascar says you must use a roll cage.

If you wish to build your own and test it, that's simple enough to do, but you may damage your tractor in the process. If you've got another piece of equipment available, like a bull dozer, slam it into the ROPS a few times when it's mounted on the N. This is essentially what the SAE testing is. Look for deflection and damage.

For rear roll over strength enhancement, it's a simple enough matter to weld up a set of legs that extend forward, either bolting to next flange forward, or hooping up and over the gearcase.

A mesh screen for the back would be a bit more difficult for the N, in that the seat is far back on the tractor, and a mesh would foul the seating of the operator. Though you could bow the mesh backwards simply enough for seat clearance.

For starting absolutely blind, I would suggest reading up on the roll bar and roll cage standards of construction required by SCCA and Nascar. They are well versed in home made custom race car protection, and it translates superbly into tractors.
