Just logged in to confirm an Oregon blade part number for my 60D. I have a 1969 Ford 1520 with a 60 inch finish mower, 2020 JD 2025R with 60D, 2009 Bad Boy (31hp professional version), 2014 JD 135SE (son in law's, I maintain). Anyhow, back to the point, I have had less than the best luck with "factory" support as to knowledge, parts availability, and general support so I have started doing a lot of business on line. One of the sites used consistently is Jacks Small Engines primarily for Gator blades and belts and no, this is not a commercial for JSE, I tend to go back to retailers that do and deliver as promised. My estimate is that I have ordered a dozen belts and twice that blades from this one site. One last example, The Bad Boy deck belt is an unusual size (152 1/4 x 5/8"). My dealer estimated 7 to 10 days on order. On line, 2 days and 2/3s the price, made in America with Kevlar and marked with the correct part number. Just be aware of Amazon junk. Honestly, I don't even trust the product description on their site, having found several over the years that weren't accurate. Do your homework, make sure you know what you're getting and I feel you will be well satisfied. Last thing, I am old, therefore by default, wise. Almost have the grandkids convinced of that.
