Maliboots - hi, I'd remove the old blades and take them with me to one of the "big box" stores, or to a place like Ace or True Value Hardware. If you're in a more rural location, one of the lawn & garden or tractor supply places will likely have replacement blades. All of those places would want to compare the ones that came off your mower with what they have in stock. I hope this helps some - good luck! Jim D/West Point, VA
