I guess I'm the oddball here. I have never quite seen the point of a "quick hitch" as it involves significant expenditure and much modification (standardizing pin distances) to solve a "problem" that in my mind just doesn't exist.
I have several attachments: york rake, snowblower, backhoe, log splitter, finish mower, tiller, posthole digger, rotary mower and box blade plus a couple of home-made doodads. They all get parked in the grass or on the dirt floor of my shed.
It's not at all unusual for me to switch implements 4 or 5 times in a day when I have a project going.
I make a reasonable attempt to park things on level ground, and I do go to some extra effort for the PHD (I lash it to a post to keep it vertical; the backhoe (it sits on a couple of old car rims and a 6x6 to keep it at the right height) and the log splitter (I built a stand for it to sit on to keep it at the right height and somewhere near level).
Yup, occasionally I have to rassle with one or another of them a little, but it's nothing a little tweaking with the crowbar won't fix. As long as I remember to grease the PTO shafts occasionally I've never had a problem there. I have both push button and collar types.
BTW I'm 63 and sat on my butt for a living for a lot of years too, but I'd still WAY rather take the time to put the PHD or the backhoe on than do it with a shovel.
Of course, I'm also an unreconstructed Luddite and my tractor doesn't have power steering, a cab, air conditioning, cup holders or an automatic transmission. Fits well in my cave tho.
