They happen to be Prince valves in a DIY installation.
I don't have a problem/issue as such, I was just pointing out that, when hooking up, a hydraulic top link doesn't provide the VERY FINE and slow adjustment of a turnbuckle style top link and that this can be a minor factor in adding to any difficulty that someone might have with hooking up implements.
I don't have enough of an issue with hooking up to use either Pat's ends or a frame style quick hitch, I do have telescoping arm ends and I really don't mind getting off/on the tractor an extra time or two - which I have to do for PTO hook-up/uncouple anyway.
"Bumping" works for me, it isn't worth changing valves and it might not even be worth adding restricters - again, for ME.
Oh, here's a bit of fodder for the safety police;
I typically dump my bucket outwards to get the bottom vertical before I hook up an implement.
I get the tractor "close", drop the bucket, do not apply the brake, then dismount.
I use the dump/curl of the bucket to inch the tractor back/forth to get it where I want it for hooking-up.
It works, it is "safe" as long as I only do it when I am BESIDE the tractor's rear wheel and not BEHIND it.
Sometimes I do this to get the top link connected; as well as or instead of using the top link's hydraulic lever.
Sometimes I can't get the top link to extend quite far enough, so I back the tractor up another inch or two with the bucket curl.
It is a bit slower and finer than the top link lever.
Works for ME.
