Most of my tractor implements weigh 600-900lbs. I cannot move these around (on dirt) by hand or even shove them to get into place, even if it's half an inch away. On two previous tractors with extendible draft links I found it took 10-20 minutes to change implements, between very careful backing up and a lot of fiddling and shoving with the draft link ends, and I was storing everything on pallets as level as possible and as accessible as possible. And without extendible draft links it would have been all but impossible.
The only good workaround I found was to store my flail mower on moving dollies inside a barn with a level concrete floor. That way, despite the 700lb weight, I could move the mower right into position and hook up very quickly. But dollies cost money and it's not practical to store really large implements like rotary cutters in this way, nor did I have a large enough barn to have all my implements inside, on that level concrete floor.
There are at least two different quick hitch systems available (ASAE and ISO) and both of them look very effective, with their own individual merits. I think it would be a plus if all tractors simply came with one. Failing that, I think a quick hitch is $100-300 well spent.
