It depends on what kind of parts you want. When searching on the Lowes site, I see the self-propelled belt: http://www.lowes.com/pd_230960-442-490-500-0017_4294857393__?catalogId=10051&productId=1235877&UserSearch=toro+snowblower+parts&Ntt=toro+snowblower+parts&N=4294857393&identifier=Outdoor+Power+Equipment+Parts&langId=-1&storeId=10151&searchQueryType=1. However, I didn't see a large amount of separate parts for sale other than a spool and a belt.
