Thanks for all the help guys. Sorry I took so long to let you know what happened. It has rained enough to drown every frog in the county.
I don't have the means to send/attach photos, so I will try to explain what I found inside the transmission case. After removing the seat and its support bracket, I had to take off the "draft control" mechanism in order to remove the access cover exposing the internal high/low shifting parts. Once I got the cover off, it was obvious what was was wrong. The hi/low gear, splined trans. output shaft and differential input shaft were exposed. The shift lever that extends through the side case into the transmission has on its end, a flat bar welded at a 90 degree angle. This "bar" is approx. 1/8 in. thick, 3/4 in. wide and 2 1/2in. long. Welded at a 90 degree angle on the opposite end of this bar is a tempered round rod about 3/8 in. in diameter and 2 1/2 in. long. This tempered rod is intended to fit into a machined groove on the hi/low gear. The shift lever slides this gear back and forth on the differential input shaft and at it's forward most position, engages both the transmission output and differential input shafts creating "high" range. Slide it backwards and "low" range is what you have.
In my situation all that happened was the "actuating rod" somehow slipped out of its groove around the sliding hi/low gear. I think the previous owner was too rough when shifting. Anyway, I was able to loosen the 2 bolts holding the shift lever in place and gain enough slack to coax the rod back into the groove. Now it works fine.
I went in to extra detail thinking someone else with the same problem might see the post and figure out how to fix theirs. It was easy, just be CAREFUL when re-attaching the cast iron draft control cover. It has an o-ring on it that can be CUT unless you're careful.
Thanks again to those who responded with help and ideas. I wish I had located this site years ago when I was rebuilding my old Fordson tractor.
