Help with 3-Point Hitch Adjustments [Kubota B3200]

[Gordon Gould]

I heard it is possible to actually bend the threaded portion of a top link if you put it in a bind. Then it becomes very hard to screw those threads in and out of the link. A close inspection might be in order.

Yes, I have done that.

If you take those screws out and unscrew the ends there are pins that keep the ends from unscrewing all the way out . You can pull the pins out and unscrew the rods all the way out .

Now that would make sense.

Always wondered what those screws were for!
Good Luck!

My Ford 1700 had a manual top link. It didn't have any grease zerks and it didn't have any "locking screws". To grease it - unscrew both ends - grease the threads liberally - reassemble. Simple and quick.

Oh, I see it. They are for limiting the rod play but not for locking it place.

Not really . The pins just keep the rods from unscrewing all the way out. If u take the screw out and turn the rod out u should see the pin its near the end .

Not sure why but many Kubota top links have those screws. LInk for B3200 parts

Wow! Someone looked it up! Everyone else hazarded a guesstimate.

The three most important words one might share (if one must share) when one doesn't actually know for certain are "I don't know."

Instead of "Just remove them and throw them away."

These are also a most valuable response from the min wage 'associate' in the big Box Store instead of several minutes of speculation wasting my time while they're paid to waste theirs.

I've a B-7800 and I do believe my top link has such screws. I suspect that they are simple caps to the sight holes there to allow one to see if grease has gotten to where it needs be. But I'd have to read my manual before concluding as much.

I would agree with those suggesting that screws long enough to contact the threaded portions of the top link would, if tightened nicely, screw up the threads of that part of the link they were intended to secure.

Removing the link might well facilitate the application of some penetrating lubricant, use of a vise to hold a part of it steady while attempting to 'free it up.' And removing those screws and looking into the voids might offer some insight into the sticky situation.

It might allow one to determine which of the ends were stuck - if not both, of course.

Top links get damaged (bent, nicked, stuck, rusted, corroded, etc.) and are relatively disposable. Toss it in your scrap pile and buy a generic replacement at any tractor store. Better yet replace it with a hydraulic top link
