I have seen this posted multiple times but I just purchased a tractor and they third function and two rear remotes took one week to ship to the dealer.Yes, Kubota does make a specific 3rd function valve kit made by Landpride, if you're willing to wait till October or November for delivery. When I bought my L3560HSTC-LE the Kubota dealer suggested looking elsewhere for 3rd function valve. Superior or not, I bought the tractor to use.
