So what is the difference between the "mule drive" belt and the "hitch and drive" belt? The ebay seller I just bought belt #473462R4 from sent me a message indicating that belt is for "hitch and drive" and that #490489R2 is for the mule drive. He went on to say that belt #477599R2 is the spindle drive belt for the 42" deck (that # shows up as "spindle" belt on the chart Ironman provided). So is 477 the belt that only runs between the 3 spindles on the deck? Undoubtedly changed that one along the way also but that would be a good many years ago. What's still a bit confusing is that, on the same chart I referred to (post #4), both 490 and 473 are listed as PTO drive belts for the 42" deck for 1968-73.

Oh well...see what happens. The belt I've been using for years is the former, so the exact same one should also work.

Check the parts book for correct nomenclature.

That is someone's own terminology, not Cub Cadet's.

That's what I figured. Thanks....
