Just one point to make... regarding the 5 HP per rotary cutter foot in diameter...
I have a Ford 1920 (31 HP at PTO), and a JD 5 foot rotary cutter. In theory, I have more horsepower than I need according to rule of thumb. However, there are situations I run into where even my tractor/cutter combination requires me to gear down to a pretty slow speed to get through a rough patch of blackberries, or tall grass. Something to keep in mind: there's "able to do it," and then there's "able to do it at the speed I want to do it." Those are often two different horsepower ratings!
