The Case CX75C SR is a mid-sized midi excavator engineered for enhanced productivity and fuel efficiency in confined work environments. Powered by an Isuzu 4LE2X turbocharged Tier 4 Final diesel engine, this machine delivers 55.2 horsepower at 2,000 rpm with a 3-inch bore and 4-inch stroke, utilizing ultra-low-sulfur B5 biodiesel-compatible fuel. The excavator features a robust operating weight of 16,204 pounds and generates maximum swing torque of 12,500 pound-feet at 9.5 rpm swing speed. With a standard boom measuring 12 feet 8 inches and arm of 5 feet 7 inches, the CX75C SR achieves a maximum digging depth of 13.6 feet and extends 20.6 feet along the ground. The machine boasts a 4,264 psi hydraulic system with 19.6 gallons per minute pump flow capacity, delivering 9 percent more hydraulic power than previous models. Its minimum swing radius design accommodates work in confined spaces with a tail swing radius of just 4.3 feet and ground pressure of 4.8 psi. The pressurized cab offers 16 percent more glass area than predecessors, providing enhanced visibility and operator comfort with a height of 9.1 feet to the cab top. Equipped with a 32-gallon fuel tank—20 percent larger than prior generations—the CX75C SR achieves 7 percent faster cycle times. Three operating modes (auto, heavy, and speed priority) optimize engine throttle and RPM for specific tasks, supporting efficient operation with a 24-volt electrical system and integrated rear-view camera providing 360-degree worksite visibility.
