Well, I called my eastern div. of Kubota and the promply called the dealer. Now the dealer is severely upset with me over it all. He says it is just a waste of time and money, but he is going to put it in. I don't think he will, is there any way to check to be sure? I told him also to do the tranny fluid level upgrade to quiet the ratcheting noise from the pto. Now he is furious! He more or less stated to me that he loses money on warranty repairs and does no like to do them. What a crock! This guy is a real jerk and I will never even buy an air filter from him. He won't get 1 more cent from me! He told me the jumping was normal. BS, I have been around and had a few tractors to know otherwise! I just want to make sure he puts the valve in, he says it won't make any difference at all which leads me to believe he won't do it. Help!
