I did some looking into this. It is now marked on the lever that when the mid PTO is engauged the rear spins at 960. The B7510/B7610 are also this way. I never realized this, its also marked on these tractors but the labeling is not as clear. The Grand L-series also spins the rear PTO when the mid is engauged. You can always run just the rear, but the mid can't run without the rear.
I can see how this could be a pain because it prevents you from mowing with a rear implement attached. However, to lower the mower deck down you also drop the 3pt as well so any implement that would be back there will be dragging anyway. One big benifit of this is that you have a 2-speed option for the rear PTO. If your running a rotary cutter you'd have the option of running at the higher PTO speed and keeping the engine RPMs down to compensate for the higher gearing.
