I've been using a 11 HP, 36" Murray lawnmower purchased by my mother in law when my wife was a child. It runs great, but I have some parts I need to replace under the deck. If I can find out when it was manufactured, then I might be able to find a maintenance book for it on the web and determine the parts I need. The model number is 8-36508X41; date is 3527.

Thank you:
