Finally cleared the P3001 code from the 4701 which had been bugging me. Thing was, one of the plastic buttons [switch?] I needed to press had disappeared from the instrument panel a few months ago. No idea where it could have gone, pulled off by a raven maybe? Stranger things have happened. Kubota dealer is a ways away so haven't gotten to them to look at a parts catalogue to see if I can order a replacement or if they are currently unobtanium. Anyway, found I could stick a finger down in the hole for the button and push it to work ok for the code clearing. At least something went right. Finger's ok, too.
