by all means save it, paint it and use it.
great old tractors.
mix up a 50/50% solution of Acetone and automatic transmission fluid.
pour this solution into each cylinder and put the plugs back in, wait a week or two and see what happens.
this solution is suspose to be the #1 penetrating fluid.
as you well know, dragging the old tractor around poping the clutch can only break some drive train parts.
good luck with the old tractor.
