<font color="blue">Oh, and I advise anyone to take the extended warranty, why you would think this is silly in my situation I cannot understand? You mean, ? I should have mercy on JD? or the dealer? I dont know what you mean by this statement. I may be stuck with this machine for awhile. I dont know if I can absorb the loss to upgrade at this point. So to me, the warranty would have been a wise investment.</font>
1) My point was that when you give someone your money, you are "voting" for their success. Your whole situation is a comedy of errors (yes, iamgott, I fully realize that it doesn't seem that way to you-quite understandably). And yes, things always look differently from inside looking out, than from outside looking in. Whether you realize it or not, my suggestion (and several others) to dump the thing and move on is the best thing to do. Not only have you apparently lost money by buying this JD, but it has obviously frustrated you, no doubt affected your health (even if nothing more than raising your blood pressure), etc. Life is short enough without diliberately aggravating yourself dealing with people who are causing you problems.
2) If you absolutely must keep this thing (the JD), buy yourself a set of shop manuals and find an independent (or another dealer - NH, KUB or even JD) mechanic-good ones do exist. Parenthetically, BEFORE I bought my current tractor I spent time with, and interviewed, the service manager at the dealer-in fact, I probably spent as much time wandering around their service department as with the salesman. Don't buy anything from JD (unless you absolutely HAVE to, such as parts). Don't "vote" for the success of people who have obviously harmed you. Buying their extended warranty may, or may not, cost them money. But it will certainly cause you frustration and loss. If you must keep it, learn to take care of it yourself-you can certainly get some help on this site.
3) Why would you continue putting on turnbuckles that kept braking when you were told <font color="blue">they were cheap pot metal</font>? Take the advice and buy a comparable NH or KUB turnbuckle, or, have one made. If the pressure relief valve has been properly adjusted, it isn't that. There have been some other posts regarding details on the geometry (and implement) issue. Follow through on that. You should certainly be able to get it worked out, sooner or later. After all, its not brain surgery.
Good luck.
