Not too often a person gets lucky with tractor problems but this time we actually did! I took some advice on here and talked to the Kubota mechanic. The problem is luckily simple and fairly cheap. There is a drive shaft under the tractor running from the transmission to the front drive axle. On each end of that shaft there is a sliding internally splined coupler that connects the shaft at the front to the axle drive spline and at the back to the output shaft at the transmission. Those couplers once the roll pins are pushed out slide onto the drive shaft and it can be removed. The coupler at the axle end was stripped clean at the end that goes over the axle spline and that's what turns out to be the noise and loss of 4wd. The mechanic said that shaft can be removed and the shield put back in place and the tractor can be used as a 2wd while the new couplers are on their way. Apparently that is a fairly common configuration of many 4wd tractors and those couplers are made of a softer metal than the gear splines to act as a shear to protect the really expensive and hard to replace internal parts. Thank you to everyone for the help to get pointed in the right direction! We may grow old but never too old to learn something new every day lol
