I have mine 2/3 installed.
It is very nice. I was concerned that i would have to remove it for filter changes, but they had that figured out. There are still lots of ways for brush to cause issues even with the skid plates. I may still end up doing some mods with expanded metal. But the real risk is for big rocks and whatnot, and these will definately be worth their price!
I cannot see any way that it would interfere with the mid pto and mower, but i would check with a dealer...
Again, I would highly recommend them....
