I think you mean as opposed to 1/4 inching hitches and the type you where you have to return to neutral manually.
JD makes some small ones that have the latter type hitch, don't remember the model
I know most of the small Kubotas have 1/4 inching valves.
There are WAY too many models and brands for me to know for sure, but I KNOW my smallish CK20 has true position control.
As far as I know, nothing in it's class does, but I'm likely not correct. Sorry, but do go to the different tractor sites and check out their models and specs.
