In 1981 the new Bobcat® 643 skid steer loader made its first debut, powered by a 28.5hp Kubota® D1402 three cylinder diesel engine. The 643 featured hydrostatic drive with diesel economy, seat bar for additional operator safety, tip-up ROPS for easy maintenance, and the popular Bob-tach® system for attachment versatility.
