The OP sounds like he already has some experience with tractors, so maybe the cost savings will be worth it to him.
Personally though, I would not even consider a 2WD model, but I don't work my tractor nearly as hard as some/most people do.
I made the mistake of buying a 2WD F250
one time.....after getting stuck IN MY DRIVEWAY, after I stopped cussing that thing out and kicking myself in the ass for being so stupid as to buy a 2WD truck, I sold it and never even considered a 2WD model anything....
On that note.....My SIL has been bragging non-stop about him finding a "beautiful Texas truck".......It was supposedly nicer than any "ratty/shitty old Michigan truck" he could ever hope to find

.......So he shows up 2 days ago to show it off........................
Yep, you guessed it...........2WD.
I just walked away shaking my head, smiled and said.."nice truck"..

.....(He would buy a nicely shaped turd if you told him it was from Texas....)
