CASE 621E WHEEL LOADER

Technical Description

The CASE 621E is a robust articulated wheel loader designed for demanding construction and material handling applications. Powered by a 6-cylinder, turbocharged and aftercooled Case Family IV 667TA/EDB engine, it delivers 156 hp (116 kW) at 1,800 rpm and 146 hp (109 kW) net, with a 33% torque rise for strong performance under load. The loader features a Z-bar linkage for high breakout force of 23,249 lbs (10,546 kg) and a rated bucket capacity of 3.0 cu yds (2 m³), with a bucket width of 8.6 ft (2 m). Its hydraulic system provides a pump flow of 45.2 gal/min (170 L/min) and a relief valve setting of 3,600 psi, enabling fast cycle times: 6.3 seconds to raise, 4.7 seconds to lower, and 1.3 seconds to dump. The transmission is a 4F/3R proportional type with electronic control module, offering torque-sensing autoshift/manual shift and modulation for smooth operation. The loader has a maximum hinge pin height of 12.6 ft (4 m), a dump clearance at max raise of 9.2 ft (3 m), and a reach at max lift and dump of 3.4 ft (1 m). With a wheelbase of 9.6 ft (3 m), a turning radius of 16.9 ft (5 m), and a ground clearance of 1.3 ft (0.4 m), it delivers excellent maneuverability. The operating weight is 27,406 lbs (12,431 kg), and it is equipped with 20.5 R25 tires. The machine features a 24V electrical system, a 65A alternator, and a 65-gallon (246 L) fuel tank for extended operation.
