UPDATE.....
Yesterday, I got a new replacement cylinder. When pulling the original cylinder out, I compared the two by pulling on the ram. Big difference in the resistance. I am guessing that after 35 yrs, the seals on the original cylinder, are just worn out. Anyway, got the install new one installed, and took the tractor for a spin. All is well and good.
I would like to thank those who responded with comments and suggestions. This was my first attempt at "power steering". Through this process, I gained some knowledge on how this system works.
Thanks again,
