KEN - My Super H was Our mowing tractor, and since it wasn't a Super H-TA even though it went down the line @ FARMALL with probably one ahead of it and one behind it it doesn't have LPTO. With a sickle mower I'll take the transmission driven PTO any day mowing tangled alfalfa for when the sickle plugs up and the slip clutch starts chattering everything except the hyd. stops....Hit the clutch, raise the bar, shift into reverse to back up & clear the bar, shift back into forward gear, 3rd (5 mph) or 4th 6-1/2 mph) ease forward, drop the bar. let out the clutch and go back to mowing. When I mowed with the SUPER M-TA I had to disengage the LPTO and re-engage it while still shifting which required about as many arms as if I had been on one of those miserable 2-cylinder green things!
When We ran the Brillion 6 ft rotary mower (bushhog) with the Super H, Yes, the inertia of the blades did push the tractor around until You could get the tractor back into neutral or disengage the PTO which in close quarters WAS much nicer than using it with a transmission driven PTO tractor. But most of Our work was in wide open 20 acres, 40 acre, or 80 acre fields and even with the SUPER H all You had to watch out for was making too tight of turns and getting the hammering back through the transmission from the PTO shaft on the mower. When We mowed roadbanks, or around farm buildings the SUPER M-TA or later the 4010 jd went on the mower.
If You notice I did mention about close quarters verse wide open spaces. I've never used an over-running clutch but I'm sure they are Very annoying as You say. Handiest bushhog Dad ever had was a 5 ft FASTHITCH mounted mower We put on the 450 FARMALL....It was built like a battleship and if You could drive the tractor over stuff it would shred it....and the 450 did have LPTO....and since the bushhog was fully mounted You could chop two rows of cornstalks and make a pivot turn and take the next two right next to them, and run 6-1/2 to 7 mph all day long.
