I would also like to explain, I use to own a Kawasaki Brute Force 750 4x4 ATV, that had a front locking differiential. That ATV had ITP Wheels, and Tires. The Tires were 26 in Mudlite XL's If your not familiar with them, then you can check them out, that are similiar to AG tires in tread design. When I would go offroading, through mud, over logs, up steep hills, over rocks, etc.. 4 Wheel Drive would have be the appropriate thing to have. 2 Wheel drive, would have been real difficult to take a lot of places I took it. The thing with an atv though, it is not a tractor. It isn't designed like a tractor, it has 4 equal tires, with a mid engine design, that places an evenly distributed weight over all 4 tires. It was effective in muddy conditions etc.. I have 4 wheel drive Toyota Tacoma pickup truck. I drive in 2 wheel drive 98% of the time. My truck could serve every need I have basically in 2 wheel drive, but 4 wheel drive does come in handy in the winter, and other situations, It does. I expect to use the 4wd in it though like that. I have taken it off roading by the way. If you know the topography of Southern West Virginia, yes there is plenty of steep mountains to climb, mudding, and off roading, etc. I have seen some video's of people take 2 wheel drive Fergies off roading, that seemed to get by ok. I don't reall plan on doing that, but my point is for what I plan on doing, 2wd will likely work best for me. If I get stuck in the field, I will likely be able to use my pickup truck to pull it out.
