Rear PTO horsepower?

16.7 pto hp is what it produces. I figure it doesn't matter which PTO is used.

They both come on at the same time - driven by the same linkage (pretty much, but I don't want to try and publish a tech manual here). As long as you are running an implement on one or the other, you'll get the same HP output (pretty close, at least) for either connection.
Not sure if this is what you are asking, but I suppose you can (in theory) hook implements up to both PTOs at the same time, but that isn't a good idea. The design of the tractor and the implements (I'm pretty sure) assumes that you'll use either one or the other. So if you're thinking about using a mower on the mid PTO and something else on the rear PTO at the same time - doesn't sound good.

The tractor's engine is capable of making a certain amount of power. You can use any amount of it up to the maximum. When idling with no attachments running, the engine makes very little power - it uses very little fuel, makes less heat, less noise, etc.
As you add load (as you resist the engine turning) more fuel goes in, more power is made, more heat, more noise etc. up to the maximum the engine can do.
The power-take-off shafts and the drive wheels share whatever power the engine makes. If there is something taking 8 hp on the rear pto, and the wheels are using 4 or 5 to move the tractor up a slope, your BX would have 3 or 4 left you could use at the mid pto. (maybe not practical)
BTW, the pto speed is directly proportional to engine rpm. It is not constant at 540 rpm (unless the engine runs at the corresponding rpm - usually about 2300 depending on model)
Hope this is useful. Sorry if it's too basic.
On the subject of multiple attachments, it is rare that you would find a situation in which that would work well. The idea of two mowers - one on the rear and one sidemount, running from the mid-pto is appealing in theory - but that's a lot of machinery to keep track of - you'd be watching where the side cutter is and not notice a rock the rear one is about to eat.

On the BX2200 you can select mid PTO, rear PTO or both at the same time. The only time I can see the need to run both is when you have a MMM and grass catcher. In this config. the MMM uses the mid PTO and the grass catcher uses the rear.
That's exactly my question. I want to attach a trac-vac or similar PTO driven collection system to the rear PTO while engaging the deck as well. The literature states I need a minimum of 13.5 horsepower available (rear I am assuming)
so if the BX takes up so much HP and the deck takes up so much HP, I doubt I will have 13.5 HP left for the rear but I guess it's possible. I could just tow a unit with it's own 8HP engine but then I don't understand the trac-vac specifically made for the BX series (needing min 13.5 HP rear). I hope this makes sense because I lost myself.....

I have 5 acres but only need to clean up about an acre of it.
Fall cleanup is a chore since I have a portion of my property with lots of trees boardered by a full fledged forest. The collecting will be mainly leaves so I need a unit big/strong enough to collect and reduce. I don't want to get something too small or something that will burn up the new BX. I don't plan on collecting grass clippings on a regular basis. Anyway, I have until mid/late October to figure it all out.

don't know why u would want to run 2 implements at the same time? but if u did i do beleive u would not have enough power to run either efficently(just my guess)

Have you looked at Kubota's grass catcher system? It uses both pto shafts one for the deck and the other to run a blower to pull the grass out from the deck.
