Hello sheep farmer , I clicked on the link about the 3 point control valve you sent me, but i couldn't get it to come up . Could you please check to see it is correct , I would appreciate it . Thanks
It works ok for me, but I edited it so it comes up on page 1 of Ray's thread in case that helps. But as noted above many of the photos are gone, so you can try to piece the text of the thread with the photos he has added here.

I believe the same thing TEG mentioned...

Kubota isn't going to replace an expensive part if an adjustment is all that is necessary. My valve was worn either due to maladjustment on installation or a defect in the valve during manufacture -or design. Some have mentioned an improved valve used in replacement but I cannot confirm that as my replacement had the exact same serial number as the original.

If you bought a new valve and then measured all your linkage positions before breaking the defective valve down, it should be a simple case to reset the new valve to the same clearances. Getting to the valve couldn't be much easier as its under the driver seat on the "toilet tank lid."

Be sure and cover the rear end with foil or a towel to keep foreign bits from entering the rear end.

Not "always true" when you take into account labor for either job. Granted if new one has to be adjusted anyway then most likely they will start with adjustments to existing one.
