gmtb42 thank you for your reply, I have read all the posts on this problem, and wish I had before buying this tractor. At its present operating condition it is unacceptable to use as a final grade machine. As I had stated before, I own Ford and Massey Ferguson tractors involved in my landscape business, didn't even know a 3 point hitch could be so erratic until purchasing this L3000. I had always heard what a great reputation the Kubota's had. From what I have read on TBN, even with the new style valve you still can't achieve infinite or feathering operation with the hitch. I cannot believe that a tractor manufacturer can design and call this unit acceptable [maybe China] I guess I'll stick with my Fords and Masseys'
