The Craftsman 536.8145 is a riding lawn mower produced from 1956 to 1960 by Western Tool and distributed by Craftsman, a part of Sears. Built in Des Moines, Iowa, USA, it originally sold for $300 in 1956. Early models used a two-cycle 4 hp Power Products AV-80 engine, with a manual recoil starter. The mower features a friction disc transmission with infinite forward and reverse speeds, two-wheel drive, and manual steering with an open operator station. It weighs 264 lbs and rides on 10-2.50 front and 12-3.00 rear lawn/turf tires. Attachments include a 24-inch mid-mount Craftsman mower deck with a single blade and adjustable cut height from 1.5 to 3 inches. Serial numbers vary by year from 1956 to 1960. Limited information is available, but models from 1958 onward were advertised with a four-cycle engine and electric start.
