I have a John Deere JS63 with mulching blade, 3 years old. Recently, when mulching, the clippings are not mulched up, just blown out the bottom of the deck, unmulched.
I have cleaned out the bottom of the deck of all old grass, but still it is not mulching. Blade is original, resharpened about 4-5 times.
I figured I would try a new blade. Guess what, part number at John Deere is not listed anywere on the web. Drove an hour to the Home Depot were I bought it, sorry, we don't carry John Deere push mowers anymore, and no parts.
Can ANYONE direct me where to find a simple OEM 21" mulching blade for a John Deere JS63?
