Thanks to Bob & Roger. Sold it & moved it out today. Took out the sun gears & rolled freely right up the ramps & onto the equipment trailer. JD 550G moved it easily (weighs 20,000 vs. 14,000 Cat). Did have a tough time getting the cover holding ring off tho. Must take a special tool. Worked around it with a nailset punch. Took 2 hours getting one ring off & 10 minutes getting 2nd one off. Looks like there ought to be a slot cut to get behind the ring but found nothing. The covers themselves came hard. Had to take out the plugs & pull & pry from the inside with a hook while pecking with a hammer. About a half hour for each cover.
