Examine your Poulan riding lawnmower closely. Locate the sticker or plaque that lists the information about the lawnmower, including its model number. Some models may actually have the year of manufacture stamped on the sticker or plaque along with the model number.
Look up the model number on a website with a list of model numbers and corresponding year models. Mower Parts Web (see Resources) provides a chart listing all current Poulan mowers, their model numbers and the corresponding year model.
Contact Poulan Customer Service, which is operated by Husqvarna, and provide them with your model number. Request they provide you with the year that particular model number mower was produced. The customer service number for Poulan for wheeled equipment is
