I know this sounds goofy, but I bought my Craftsman LT1000 used. It has a 42" cutting deck, but only has one blade installed. I'm told that it is supposed to have two. How should the two blades fit?

Thanks.

If you give us the correct model number starting with 917 I can be more specific. http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Riding-mower-tractor-Parts/Model-917288514/0247/1509200/1106116P/00007?blt=06&prst=&shdMod=

I'm sorry... it is 917.271633. Thanks again.

You can zoom in on this http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Riding-mower-tractor-Parts/Model-917271633/0247/1509200/P0104108/00010?blt=06&prst=0&shdMod=917271633 and by surfing this same site likely buy a manual. Sears rearly allows for a free download

So, it does just use one blade. Thanks for the info!

Nope, two. Blow the diagram up and look at part #11, blade. This one is exploded to show you all the mandrel parts but , to the left, is an assebled second balde. Maybe try for that manual to help.
