One, way too expensive and I'd need multiple implement sides anyway. I have no trouble hitching up anything PTO driven anyway.
To me, almost is like creating a problem and the solving it for a price. In my case I only run an over running adapter on my PTO stub if an implement don't have a built in over running clutch and all of mine do except the shredders.
Kubota's have notoriously weak PTO brakes, especially my M9's, consequently, I run the over running coupler which completely eliminates any inertia driven motion from the implements. IOW, I can disengage an implement at 540 rpm and not be concerned about the inertia of the PTO shaft destroying my clutch brake and replacing a clutch brake in any Kubota is a BIG job as in splitting the tractor to access it. You can see the brake if you take off the back cover, but you cannot reach it. It has to be replaced from the front.
