I ordered a new shuttle shift switch that ought to come tomorrow or the next day. I started the tractor and raised and lowered the boom with me and my wife keeping a keen eye on hose joints. Two were leaking rapidly at the FEL valve so I had some made. Plan on installing them shortly and hope for the best. rScotty, it is interesting about the wiring diagram but I will have to look for part 21. I did look up and print the parts diagram from Kubotausa and I do have the shop manual so I will check it out. Thanks.
