140 hours on my MX6000 over the last 6 months. Much of it grapple work while reclaiming fields. You'll love the tractor and it is surprisingly nimble in spite of the larger foot print. It's well planted...good balance of power, weight and size.
I have the ROPS by choice, it was not a cost decision. Everything I'm doing with the tractor is because I want to be doing it, rather than "have" to be doing it. I prefer being outside and feel more "in touch" with the work being done with the open station.
If not too late, add the 3rd Function for the grapple now, plus the 3 remotes.
Easier than adding them after the fact.
Also noted that you are tall. I found it simple to add a couple of 2 inch x 3 inch x 1/4 inch aluminum rectangle tubes to raise the seat 2 inches, helping to make it even more comfortable to operate.
