My loader valve has started leaking, and I read all the rest of the sad tales of woe where people have swapped the Kubota system for individual quick connects, etc. I decided to call my selling dealer to see what the present status of the problem resolution was. I was first informed that my tractor was out of warranty, and then this morning I got a call from the fellow who deals with warranty issues and was told that Kubota was extending the warranty on the loader valve for 5 years from the delivery date. They are sending me new parts to install since I don't want to trailer the tractor back to them for the service. The new part has been redesigned to resolve these leaking problems. I will update this post with pictures of the new part(s) when they arrive.
