After all the advice that it probably was the battery or ground, I went back and connected via starter cables the starter to a battery that I knew worked that was on another tractor. The starter turned over. So, I went back and checked the battery on the Cub again. I connected the starter to the battery via starter cables and the starter turned over. Then I took the connector off the negative ground cable and the wires look corroded. I cleaned them up and put a new connector on. Installed the starter and connected up the battery, and the starter turned over.
I gotta keep remember than when I hear hoof beats that it is probably horses...not zebras
. I thought I had checked the ground pretty well, but obviously not enough.
Thanks for the help...and patience.
