I dont know why yours is so abrupt.
Just my opinion but these are what 40 ish year old units? Been working with the original equipment all this time. I don't see much reason to reinvent the wheel.
Maybe you need a new pto switch as you say yours is difficult to move? You do know on a 782 you pull the spring loaded outer shell up to engaged it? Has a safety thing built in so it can't be accidentally engaged. Shutting off just push the switch down like a regular toggle switch.
