If you pay attention to the turnbuckle, you can usually find a place where it is visibly loose/wobbly. Just a smidge. This is where the handle will be easy to turn. Depending on whether you are raising or lowering the side with the turnbuckle on it, there may always be weight on that side, in which case it will never loosen up.
Dear jioshuavardwel. Thanks for the response. I know exactly what you describe.....I lowered the bb just to that point where I saw the turnbuckles on the tilt adjustment shaft slacken. I thought "perfect....now I should be able to adjust the shaft by-hand". I grabbed it and to my dismay, it was still really tight while the entire shaft and turnbuckles were loose against the upper/lower control arms. It would turn but only by using a large crescent wrench on it. Weird. I so think there's something going on with the threaded connection. It doesn't appear to be bent or otherwise damaged in any way so perhaps the threads are filled with dirt, etc. When I get a chance I'm going to remove the bb, remove the threaded adjustment shaft from the control arms and completely unscrew the entire adjustment shaft, check the threads, clean all the threads, reassemble and maybe that will fix it! I'll keep you posted.

My turnbuckle turns easy but I still dont care for it... I plan to modify that section with a gearbox style adjuster from an old MF 135 or Ford 3000 type lower link. It would need shortened to fit, and I would make it replace the entire section from the lift arm to the lower link so as to allow the original to be reinstalled, unchanged. But that style does not require tools to unlock and adjust, and also has more leverage so you dont have to be so centered in that lose "sweetspot".
My Kubota has a crank, which I assume is a little pinion and rack, on the right side arm. Even though there is some gear torque multiplication, it's also difficult to turn. Even when well-greased and there is little weight on the arm. It does sound to me like you have some crud in yours making it unusually tough to turn, so I bet the disassembly/clean will be very beneficial. BTW, "Fluid Film" is a very good lube for this application - relatively "dry" so it does not attract new dirt and stays in place (but pricey).

If you are still trying to shorten the link, you still have to much grease in it. Take that plug out again. Set it as short as you will use it then put the plug back in.
Success! I completely disassembled the adjustment arm, removed all the grease using a long, narrow piece of rag soaked in WD40 that I twisted through the disassembled adjustment arm and then rotated around the rag multiple times (using a few different rags) until the inside threads were finally cleaned. I toothbrush also worked well. I cleaned all the crud off the bolt threads then applied a LIGHT coat of grease and reassembled. I also found a burr on one of the threads and lightly filed it down using the cut-off wheel on a Dremel tool (that worked really well). Now the adjustment shaft can be rotated with one hand and I can put my large Cresent wrench back in the drawer! Thanks much to all who responded with their ideas.
