This tractor is a 38 and as you know hand crank only. Complete tractor was restored probably 15 years ago and has seen little use. To me, the hand crank seems much harder than expected. Even with the spark plugs removed the rotating assembly feels like it's way too tight. Even cranking it over with no sparks plugs shakes the entire tractor. I've seen people who can turn their engine over by rotating the cooling fan with the plugs removed. There is absolutely no way I could rotate this engine by turning the cooling fan. Is this normal?

How have you tried disengaging the clutch turning the engine over? If there is no difference you may have to remove the oil pan and plastigauge the bearings. I definitely this was the case with one B where the bearings were too tight, with correct clearances the problem was fixed and the engine turned over easy.

did the tractor run after the rebuild ???  Has it been setting for a while ???

You could have some rust on the liners / pistons / rings causing things to drag.. If you KNOW the engine ran good at one time, i would put some penetrant or oil acetone mixture in each cylinder and let it set for a day or two.. Crank the engine over and push this out the spark plug hole... If it seems to help, you could drag the tractor around with the truck with the spark plugs OUT and in gear.... should loosen things up..
