I don't believe you can find the blade that works on these older decks by the tractor or deck model number. I was looking for them for my 42" deck and cross referenced the IH part number for each blade with the number for a replacement blade. This gave me the length of each blade. Then I looked for a Gator blade in that length and found none. I used
