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.
