Welcome to the site.
My Cousin has a 2wd MX5100. Loves it.
I use my tractor in the woods a lot too. It's pretty hard on a tractor to do work like that. I try to not dent/scratch mine and keep a good maintenance program on it. But that kind of work takes it's toll. I bought my current tractor a year ago and it's got 425 hrs on it. I'm retired military and am caring for a 160 acre farm my Brother and I jointly own. Weather permitting I'm on my tractor every day at least for a few minutes.
Again welcome to the site. Look around. There's a tremendous amount of information on here.
Two links that I use most is "My Home". That lists any threads that you have posted to and that have a response since you last looked at it.
And "New Posts". That lists every thread that has received a post since you were last on the website. Lots easier than going to each specific forums and scanning for something that interests you.
You'll find both of those at the top of the page.
