Ok, here's the deal. PTO on and off is effected by flywheel inertia amount/mass on implement. My dealer almost won't sell you a brush mower without a slipper clutch for the electric PTO tractors. When you start up an implement with a lot of flywheel mass, you need to do it at low RPM. I do it at idle to reduce the "hit". I've done it at high RPM's, and I've turned it off too at full throttle. So far, I've had no problems, but I do try and start and stop at low RPM's to reduce the stress.
Our 5420 has an "old style" clutch lever to engage the PTO, when you disengage at high RPM, the mower blades keep turning for up to a minute. So, this type would'nt help you out if you need fast starting and stopping of the blades. Maybe if your field was knocked down first with a brush mower and then switch over to a finish RFM mower. They have less flywheel inertia, and are closer to the 3 pt hitch for less up and down "pivot effect" from your above equation.
Good luck on your search...Kyle
