Here is a link to some old PAMI combine evaluations that were done in Western Canada some years ago. Machines were tested in wheat, barley and canola and they are all compared to a "reference" combine with was actually a JD 77xx combine. Don't list your 52 or 62, but a R72 is on the list as is a 9500 and 1666. They have stopped doing these tests due to the cost so there is nothing newer than this to compare them in a real objective way.
