Nice tractor........funny thing, it looks very similar to the 2520 that I just bought.
You and I are about the same size, and I originally found that my right foot, was forced into a somewhat uncomfortable position while driving. It seemed the "go" peddles were too close, and I had to keep my foot at an uncomfortable angle in order to access the peddles, even though I have the seat as far back as it will go.
A tip on this forum suggested to cut one ring off the seat supports, which I did. This made a world of difference in my case. Much more comfortable for me at least. Just thought I would mention this in case you found the seating a little cramped.
I would liked to have seen the speed range in low just bumped up a little faster. I can mow my grass in high, as I don't have any steep hills, but still, I think a little higher speed in the low range would have solved everyone's problems, with the 2 speed tranny issue.
I think on a 3 range hydro, the low would be a "creep" speed, and probably wouldn't be used much anyway, so in effect it would still be used as a 2 speed unit.
Enjoy your new toy........I sure like mine, shoulda' had a loader years ago.
