Well I read through this entire thread this morning. A lot of interesting thoughts and ideas.
I used to mow with a 12 foot pull type finish mower. It did a very nice job and got under tree limbs and such fairly well, then I'd trim up with a little JD rider.

Then I picked up an old Kubota
F2000 a whopping 19 hp with a 72 inch side discharge deck.
My yard is very rough and lots of trees and hills, I do not mow fast, heck low range and maybe midpoint on the hydro speed. The cut is good and power is not an issue for me. I do shift it into and out of 4wd frequently as I don't care for the turning radius in 4wd and the amount of tire slip. That said turning uphill while circling a large tree I'll often engage the rear axle so as to not spin the main tires as much.
I will often do my trees and shrubs by going back and forth while moving sideways along the edges or around a tree with low branches.
I'm well pleased with the front decked
F2000, if it goes out I'll likely look for a similar unit.

I did add an air spring to the old worn out seat suspension
