Don,
I am a total newbie to this world of tractors and I (and my wife!!) purchased a 7500 this spring to help clear land for our new home construction. I (we) am (are) so impressed with this baby. We cut mostly oak trees (approx. 12-18" diameter) and I can't tell you how handy it is to have this tractor. We also have lots of stone walls which we need to move. We blasted ledge for the basement and did I have a pile o' rocks!!!! I didn't move all of it, but I picked out all the good topsoil I could with the FEL and heaped it up for landscaping later.
I'll try posting a photo of the beast working on the mountain of rocks....
We don't regret for a minute buying this machine. It has taken me a little seat time to get a feel for what is comfortable (e.g., how big a rock/log I can move with it; how to get a full bucket scooped up; techniques to move objects that are beyond the brute strength limits [use the rock sled on wet ground, etc.]), but I tell you it is so satisfying to get a week's worth of manual labor done in a weekend!!
So, for what it's worth from someone with not much experience (yet), I don't think you will regret latching on to one of these.
PS I haven't even mentioned what I'll need it for this winter in Maine!
