Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Does anyone know any web sites that would provide information on lawn and garden equipment.  I am about to get a job in the lawn and garden department at sears and I dont know anything about these products. If anyone knows of a website that discusses information on lawn and garden equipment, please let me know. Or if you have any suggestions on how i can get this information.  I just want to have a basic knowledge of things before i start my training.  Thanks
