B-Series

Originally designed as a basic machine to run Walker discharge and mulching decks, the B-series has evolved into one of the most agile and versatile tractors in power equipment. The B’s hillside performance is unmatched by competitive machines in the industry. The B-series tractors easily fit into tight spaces and can also reach up to do larger jobs with bigger decks up to 56 inches. A variety of year-round attachments make the MB a no-nonsense workhorse for homeowners and commercial operators.
