Welcome, we seem to think alike! I took delivery on a NX5010C last week and the 60" Wicked Grapple came this week. We needed the cab for East TX summers and our uses favor shuttle shift.
My Dad passed away nearly 10 years ago, but I don't I would ever catch him on a tractor. Enjoy your time together with Dad.
In many ways, I had more interests in common with my FIL (also passed away). I think that he would have been like a kid in the candy store on our retirement property in the country - tractoring, hunting, fishing, piddling in the shop ...
I'm pretty anxious to get my 3rd function hooked up; that grapple looks like a TOOL!
