I found a drive-over mower deck that came with a 2370 tractor, and the seller said that he doesn't use it and wants to sell it. Are the mounting hardware and the mower deck the same on the Series 70 as they are for the Series 80 drive-over mower decks? The deck is part number RCK54D26BX. The seller doesn't have any of the original manuals, so I will also need these to get the mower mounted on my BX23S.
