When I was a kid working on the uncle's farm the largest tractor that pulled the big implements had a quick hitch. The nicest thing I recall is you could back to the implement and get it lined up and the lowers attached without getting off the seat. Made it much easier for one man.
My Speedex hitch is similar in that the implement drops down into slots and the arms don't spread - only difference is once it's in it's secured with pins rather than a latch. I can back under my disc, raise the lowers up and pull it from the fence row before securing it.
My other implements don't stand up when detached from the tractor. They have to be lifted onto the hitch. Fortunately they're light, and it probably is faster than sticking pins through eyes.
The downside to the quick hitch - the implement has to pretty much exactly fit. Too wide or too narrow and its useless. I've run into that with my Speedex, its hitch is Cat 0 which means exactly 20" between the arms. You'd be surprised how much Cat 0 stuff is 21" wide. Since the arms don't spread the implement is useless to me.
Which brings me to my last point. That quick hitch is Cat 1. Are you using Cat 1 implements?
