IF (and that is a big IF) they were able to "up-grade" the valve to the Grand-L style, so what? I am still not sure why every one thinks they should get the best 3 point valve available on an economy tractor. Kubota has sold 10s of 1,000 of these units and the "normal" valve that is supplied with them works for over 90% of the people who buy them. If you want a better valve, then buy the better tractor. Sorry, but to me this is no different than saying that your
L3800 does not have tilt steering and you want it so it should be given to you for free.
If you want tilt steering, buy the model that has tilt steering, don't buy the most basic tractor and then get mad because you don't have all the best features. If all you do is use the 3-point, then you should have tried it out before you purchased it. If "everyone" who has one knows it is so bad (as most people hear act like), then it should have been easy for you to figure out that there was a "problem" before you made your purchase. I know that these thoughts won't go over very well on this post, but really, it is the truth.
