If you never use your tractor when it's too cold, or too hot for the oil, much depends on the anti-wear additive package and little else.
If you want the best metal-wear protection, buy a racing, or off-road diesel oil and not oil made for highway use vehicles. That because many anti-wear ingredients were lowered in 2009 for highway oils.
Also depends if petro-based, or non-petro-based.
The oils that can sustain the highest temps - are sythetic single or multi-grades, and some petro-based single grades.
The oils that work best in extreme cold are multi-visc sythetics.
The other issue is the use of polymers to make multi-visc oils from petroleum. They can cause deposits on piston rings, whereas sythetic multi oils do not (generally speaking).
Now, if you never want to think about temps and your oil, and IF you might have to use your tractor at 30 below zero F, or 110 F above . . . buy a sythetic off-road diesel oil like 0W-50, 5W-40 or OW-40 and you'll never have to think about it again. Deere, Delo, Shell, and many other places sell it.
For example, Deere Plus 50 synthetic-base oil. It's a 0W-40 rated oil. Has more anti-wear additives then highway EPA rated oil. Has a working temperature range from 40 below zero F, up to 122 degrees F.
Petro-based single-grade 30W oil is fine, but can damage your engine if you start it below 20 degrees F.
