BigMike,
I've owned a 4wd pickup for over 30 years now and while it's rare that I use the 4wd, when I need it, I'm always very glad I have it.
My neighbor owns most of the farmland around me and when we discussed new tractors his advice was - no need for 4wd. He's running large 190+ hp IH/Case (don't know the model numbers) that weigh 6-8 tons or more I'd imagine and so maybe with all that weight and with the lay of the land 'round here it's fine.
Seems the concensus on this site is that 4wd is a must have and with my experience having it in my pickups all these years, I tend to agree and so I went with it in the new tractor. No regrets though. The fact I haven't used it much yet probably means I'll use less fuel.
I love this new machine. It's my first and it's been great. :thumbsup: :thumbsup: :thumbsup:
