Mack Trucks DM600
The DM600 was purpose-built for mixer and dump body work — a set-back front axle gave it the tight turning circle essential in construction sites, and the air-assist transmission, wet-line hydraulics, and frame-mounted power take-off were standard equipment. It became the definitive US concrete mixer truck.
