CASE 621D XR WHEEL LOADER

Technical Description

The Case 621D XR wheel loader features a robust 136 hp (101 kW) turbocharged and air-to-air cooled six-cylinder engine with 409 cu in displacement, delivering a torque rise of 33% at 1200 rpm. It has a breakout force of 23,936 lbs (10,857 kg) and comes with a standard bucket capacity of 3 cubic yards (2 m³) heaped and 2.6 cubic yards (2 m³) struck, with a bucket width of 8.6 ft (2 m). The machine’s operating weight is approximately 26,364 lbs (11,959 kg) with dimensions optimized for versatility: 24.5 ft (7 m) length with bucket on ground, 7.9 ft (2 m) width over tires, 10.9 ft (3 m) height to the top of the cab, 9.6 ft (3 m) wheelbase, and 1.6 ft (0.5 m) ground clearance. The bucket dumping clearance maxes at 10.7 ft (3 m) with a hinge pin height of 14 ft (4 m). Its hydraulic system includes a 45.2 gal/min (170 l/min) closed-centered, pressure/flow compensated pump, achieving dump, raise, and lower cycle times of 1.5, 5.4, and 5 seconds respectively at a relief valve setting of 3600 psi. Transmission is a 4 forward/3 reverse electronically controlled torque-sensing autoshift with manual modulation, enabling max speeds of 24 mph forward and 15.6 mph reverse. Fuel capacity is 50 gallons (189 l), and operating voltage is 24 V with a 70 A alternator. The front and rear axles have fluid capacities of 5.9 gallons each, with rear axle oscillation of 24°. Tire size is 20.5x25 L3, and the turning radius measures 17 ft (5 m). This loader combines power, hydraulic precision, and maneuverability for demanding construction applications.
