Cat completely redesigned the tractor for its 613G scraper with a C6.6 engine delivering 3 percent more horsepower and a new torque converter increasing rim pull. With faster elevator and travel speeds, the 613G can load material as much as 13 percent faster than its predecessor. It has an 11-cubic-yard heaped capacity. Safety updates include an articulation neutralizer valve that prevents the machine from articulating when the operator enters or exits the cab while holding the wheel. All daily service points are at ground level. The operator can swivel the seat for a more comfortable view to the rear during loading. Hydraulically actuated brakes replace air braking found on the 613CII.
