Replacement parts for Craftsman riding lawnmowers can be purchased from Sears, engine repair shops and online retailers such as Amazon.com. Since the Craftsman brand is produced by Sears, Sears has a parts store called Sears Parts Direct that can be used to quickly find replacement parts for Craftsman products.
Replacement parts purchased from a Sears online or retail store may be more expensive than parts found elsewhere, but these parts are more likely to be original lawnmower components. The Sears Parts Direct website also has guides that can be used to aide in the repair process. Parts purchased from other vendors may or may not be genuine parts and therefore may not work in all circumstances.
