Brian generally doesn't mess with manually actuated valves for cabbed machines I don't believe. He also warned me & I found out that the rear remotes on the Grand Kubotas are crap. It's the least happy aspect on my
L4060. I'm on my 3rd tilt valve & my tilt cylinder still leaks down in under an hour. My toplink is ok & only stretches an inch or 2 over a few hours, after they replaced it once. The crap cylinders from the dealer than never fit right & several leaked badly externally had the same issues (mostly relevant on the ones that didn't leak). Those cylinders got replaced by a pair from Brian at Fit Rite, which I have been happy with.
