The Pat's is just a couple of snatch hooks to extend the lift arms.
The Woods is a frame, there are many lo/no name brand versions of it.
Supposedly you can change implements without leaving the tractor seat with the full frame ones, unless there is a PTO shaft to deal with.
Unless you have exactly the same geometry on your implements you will have to mess with the height of that top hook when you change implements.
Even then it might not reach far enough into the implement frame to find the top link pin.
I have an el-cheapo version of the full frame, it works but I don't find it to be any sort of time (or labor) saver.
Quite frankly I only keep it around to avoid cutting the PTO shaft for my tiller, it spaces the tiller back about 3 or 4 inches - just right, but only a fortunate coincidence.
I think the other thing with these kwik hook up devices is that you probably need the lower pins and lift arms to agree on level, i.e. if the implement and tractor are tilted a little differently you will lift and latch one side, continue lifting and probably move the implement before the other side engages. Probably fine if you have everything on a flat concrete garage floor - I don't.
Hmmm, I guess I'm saying I wouldn't bother with either one, but I don't mind hopping off the tractor to hook things up - and have to anyway for tiller, mower and everything that has hydraulics.
FAR more useful is telescoping arm ends and I don't think the Pat's hooks work with those.
So, please tell me, why do you think you want/need either one ?
