CASE 721D WHEEL LOADER

Technical Description

The CASE 721D wheel loader is a robust construction machine featuring a turbocharged, air-to-air cooled 6-cylinder Family III 668TA/E2 engine delivering 170 hp (127 kW) at 2000 rpm with a torque rise of 24.8%, optimized for high-performance loading cycles. It boasts a breakout force of 29,806 lbs (13,520 kg) and a heaped bucket capacity of 3.6 cubic yards (2 m³) with an 8.9 ft (2.7 m) wide bucket, enabling efficient material handling. The loader has a dump clearance of 9.5 ft (3 m) at maximum raise and a reach of 3.9 ft (1 m) when fully lifted and dumped. Its dimensions include a 25.3 ft (8 m) length with the bucket on the ground, 8.6 ft (2.6 m) width over tires, 11 ft (3.3 m) height to the cab top, and a wheelbase of 10.7 ft (3.3 m). Ground clearance is 1.2 ft (0.36 m), with rear axle oscillation of 24°. The operating weight is approximately 30,644 lbs (13,900 kg). The hydraulic system employs a closed-centered, pressure/flow compensated pump with a 54.5 gal/min (204 l/min) capacity and 3626 psi relief valve setting. Cycle times are efficient with raise at 5.6 seconds, dump at 2.4 seconds, and lower at 3.3 seconds. The transmission is a 4-forward and 3-reverse gear proportional system featuring an electronic control module with torque sensing, autoshift/manual shift capability, and modulation, enabling a maximum forward speed of 23.6 mph (38 km/h) and reverse speed of 16 mph (26 km/h). Fuel capacity is 65 gallons (246 liters), supporting extended operation. Electrical systems operate at 24 volts with a 70-amp alternator. The CASE 721D is suited for demanding loading applications requiring power, durability, and operational efficiency.
