I do Know that the Older 40 Loader could Be used on the X465 Which is what Deere Corporate told me in 2003 Because the 45 loader interfered with the air Cooled engine on the X465 So I’m willing to Bet You could Make a older 40 loader work on a X700 series Because the X700 frame is Not that different from the Older 425 thru 455 frame:thThumbsU
