Just a quick question.

What's the question?

JKT:
He wants to know the belt numbers. Pretty obvious.

Here you go.

Lawn and Garden - Dayco (http://www.accessdayco.com/lawn#/JOHN%20DEERE/Lawn%20Tractor/LT155)

Seems like you'll have to repeat the search. These will be Dayco #'s

Go to a Local NAPA Auto Parts store and give them the Dayco #.

Maybe obvious to you - not obvious to me or I wouldn't have asked.

I wouldn't have known the answer if the OP had included an actual question in the text, as AMHD advises.

Obviously OP didn't agree with me because I got a reddie based on my "incorrect" answer.

Hi,
It gets worse than that. There are two different Freedom 42 decks and they use different belts. Try looking in the OPEbycrigby link in my sig and the Deere decks to identify which you have.
Peace,
Clarke
