CASE 721C XT WHEEL LOADER

Technical Description

The CASE 721C XT is a robust articulated wheel loader designed for heavy-duty construction and material handling tasks. It features a turbocharged 6-cylinder Cummins 6T-830 engine delivering 165 hp gross power and 152 hp net power at 2200 rpm, with a torque rise of 41% measured at 1300 rpm. The loader’s bucket has a heaped capacity of 2.5 cubic yards (2 m³) and a breakout force of 28,097 lbs (12,745 kg), supported by an 8.6 ft (2.6 m) wide bucket. The machine provides a max hinge pin height of 12.7 ft (3.9 m), dump clearance at max raise of 9.5 ft (2.9 m), and a reach of 3.9 ft (1.2 m), optimizing loading and dumping efficiency. It has an operating weight of approximately 29,856 lbs (13,543 kg) and a ground clearance of 1.4 ft (0.43 m). Dimensions include 23.9 ft (7.3 m) length with the bucket on the ground, 8.4 ft (2.55 m) width over tires, and 10.7 ft (3.26 m) height to the top of the cab. The wheelbase measures 9.6 ft (2.9 m), and the turning radius is 17.3 ft (5.27 m). The hydraulic system features dual vane-type tandem pumps with a total flow capacity of 18.6 gal/min (70.5 L/min) and operates at a relief valve setting of 2775 psi, enabling 5.4 sec raise time, 2 sec dump time, and 4.6 sec lower time. The transmission is a 4-forward/3-reverse gear proportional type with torque sensing autoshift and manual shift options, achieving max speeds of 24.2 mph (39 kph) forward and 17.1 mph (27 kph) reverse. Fuel capacity is 53.9 gal (204 L), hydraulic fluid capacity 40.5 gal (153 L), and the machine operates on a 24 V electrical system with a 65 A alternator, designed to ensure reliable performance in demanding applications.
