Bob,

If you know the factory model number (not the 252-h that's on the side of the tractor), generally found on a plate under the seat or some other location on the tractor, you might be able to download documentation from Toro's site. I've placed a parts search link below. If your model number works there, go to Toro.com, and click on one of the links such as "homeowner" under "product information." Then follow the subsequent links to try to locate the manual you're looking for.

Thanks john, I was able to determine I need a 07-07bk01 bagger for a 37" deck.
