^ I have no problem with no ROPS, I have an issue with no ROPS and using the machine on someone else's land, especially with no insurance.
My 35 has no ROPS, but it's used only on my property. Also agree with the trans tunnel getting hot. Mine gets very uncomfortable after a few hours running the brush hog or flail mower, good call! Live PTO is a must, and if not, get a ratcheting PTO adapter so you don't end up in a pond, through a fence, or whatever.
"ratcheting PTO adapter"........ is properly referred to as an....... "Over Running Clutch" (Steiner Tractor $65).
The OP absolutely should NOT use a bush hog type mower on a 2N, 8N, or 9N without an over running clutch!
This is a safety issue!
I have had my 1951 8N for exactly 49 years.
I used it for grading, and plowing for many years.
It did the job, but ONLY for my own work.
Also: A loader on any 2N,8N,9N is very problematic, as they have no power steering
I am not afraid to operate without ROPS, although I do only have flat ground
I actually removed the ROPS from my 48HP Kubota TLB, because it was a nuisance.
The OP should at least consider a newer tractor than the 8N....something with power steering, and live PTO.
My 8N has been sitting in a corner of my barn for the past eight years.
I keep a fresh 6V battery in it with a maintenance charger attached......but.....I never use it!
If the OP wants a sweet little (32HP) Ford, he should spend more, and find a good Ford 1920.
1988 - 2000
I love mine!
An older Massey (with PS) would be a good choice also.
Having insurance when working off of your own property is a absolute MUST!
