CASE 621C XR WHEEL LOADER

Technical Description

The Case 621C XR is a robust wheel loader engineered for demanding material handling applications. Powered by a turbocharged 6-cylinder engine producing 130 horsepower net (139 gross) at 2000 rpm, it delivers 413 lb-ft of torque with 31% torque rise, providing consistent performance across varying load conditions. The machine weighs 27,091 pounds operating weight with a static tipping capacity of 18,479 pounds, enabling safe operation with heavy loads. The bucket system features a 2-cubic-yard struck capacity and 2.4-cubic-yard heaped capacity with a breakout force of 25,002 pounds, allowing efficient material loading and dumping. Hydraulic performance is enhanced by dual vane-type tandem pumps delivering 18.6 gallons per minute at 2250 psi relief setting, with responsive cycle times of 5.4 seconds raise, 1.5 seconds dump, and 5 seconds lower. Dimensionally, the loader measures 23 feet in length with bucket on ground, 8 feet width over tires, and 10.7 feet height to cab top, providing excellent visibility and maneuverability. The 9.6-foot wheelbase and 17.1-foot turning radius enable tight operation in confined spaces, while 1.4-foot ground clearance ensures obstacle negotiation capability. The transmission features a 4-forward/3-reverse proportional system with electronic torque sensing autoshift and manual shift modulation, achieving speeds to 23.3 mph forward and 15.5 mph reverse. The 51-gallon fuel capacity supports extended operational periods, while 40.5 gallons of hydraulic fluid capacity and comprehensive cooling systems ensure reliable, continuous operation in demanding environments.
