I’m not at all trying to talk you out of a quick hitch.
I don’t have a quick hitch. Hooking up the WC68, all but one time I’ve been in a shop with a smooth concrete floor and the chipper on a dolly with swivel casters on all four corners. With the tractor turned off, hook up the PTO shaft first with the chipper back a bit and canted off to one side enough to allow room to get at least the upper part of your body in between the tractor and chipper. Then roll the chipper to hook up the left lift arm (the one without the tilt adjustment). Next roll it to hook up the right lift arm. Finally, hook up the top link. That method allows me to hook it up in 5 minutes or less (now that I’ve had a good bit of practice). BTW, the bottom of the steel shipping crate/pallet makes a swell dolly if you bolt on some casters.
If you are hooking it up on dirt or some other uneven surface where you can’t roll it by hand on a dolly, it’s a bit of a trick getting it on but practice should cut the 2 hours dramatically and I would think a quick hitch would help. I’ve done it once when I was away from home with it and it took me and a helper about 10 minutes, mostly because the splines on the PTO shaft refused to line up. Don’t know how long it would have taken if I was alone, but I know it would have been a lot longer.
To me, the problem is if you don’t hook up the PTO before putting it on the 3 point there’s not enough room for a full grown man to get in there to hook up the PTO. If you leave it back too far, you’ll pull the PTO shaft apart when you slide it out to hook up, but unless you don’t have much overlap in your PTO shaft, there’s a good sized sweet spot where you can leave it back far enough to hook up the PTO without the shaft coming apart.
That’s not exactly what you asked, so if you found that useless, my apologies.
