3-point hitch top link issue

[NoNewParts]

When I get a new Kubota, the first thing I do is put that pretty little delicate toplink up on a shelf.
Back on at trade-in time.
Cheap heavy duty toplink replaces it, grind to fit.

The idea of a chain for a toplink on some things is fine,
but run the chain thru a piece of pipe, to protect you from implement flip up in a bad situation.

Modern day 3-points like most Kubotas, are really only half there compared to Ferguson's original design.
On the original, the toplink would press in on a rod connected to the lift control with a big spring around it.
too much implement load when plowing, etc, and the pressing would raise the implement slightly with no input from the operator,
so you could continue. (draft control)

Mid range and up (e.g. M series) Kubota have draft control which will lift the 3 point if it encounters too much forward resistance. I wouldn't compare the small Kubotas to real farm tractors.

As for putting the toplink on the shelf for trade in time, why bother? When I have traded tractors (only a couple of times), no attention was paid to minor details like that. If you have something functional, I can't see it making any difference.
