You also have the option of a hydraulically powered mower.
I have a Terrain King (now owned by Alamo) 15' hydraulically powered mower. Cuts like a beast and as I understand on the newer versions, if you raise a wing, it will stop the movement of the blade (might not slow the inertia down fast enough for you, I have no clue)
Bought mine used, guy said he never replaced blades (they don't look worn like worn blades might look) so the blades are something like 20 years old.
Cuts like a bandit, no shafts to be a glaring danger, you want to make a sharp turn? Have at it.... I can essentially take the outside wheel on the mower, (like turning around a tree for example) and turn sharp enough to pivot around that wheel.
If there's a negative to the hydraulic mower (my opinion) is that sandwiched between the mower & PTO you have to have the pump and a speed changer (multiplier to take the 540 PTO up to 2,160). There are NO "quick changes" with all this hardware on there. My 1066 is essentially a dedicated mowing machine. I have to reallyyyyyyyyyyyyyyy want and need to take the mower off, to take the mower off. But it cuts like a madman. This was waist high on the sprouts and just under knee height for the undergrowth with again, 20 year dullish blades.
When I bought mine, I liked the idea of having a wing shut down if raised... (doesn't do that on my model) The edges of the farm can used to be trimmed back and I had thoughts..... but it didn't work and the first time I raised the wing, I discovered I really, really, REALLY didn't like seeing that blade spinning back there with me in the line of rotation (should it detach).... so I very quickly struck that off my list.
