2016 - 2020 CASE 721E XT WHEEL LOADER

Technical Description

The CASE 721E XT Wheel Loader is a robust, high-performance machine engineered for demanding material handling tasks. Powered by a 6-cylinder, turbocharged, aftercooled Case Family IV 667TA/EED Tier III diesel engine, it delivers 182 hp (136 kW) gross power and 172 hp (128 kW) net power, with a peak torque of 596 lb-ft (808 Nm) at 1300 rpm and a 31.4% torque rise. The loader features a 4-speed forward, 3-speed reverse transmission with electronic control module, enabling torque-sensing autoshift, manual shift, and modulation for optimal control and efficiency. Hydraulic system performance is enhanced with a closed-centered, pressure/flow-compensated pump, providing 31.6 gal/min (117 L/min) flow and a 3600 psi relief valve setting, supporting fast cycle times: 5.6 seconds for raise, 3.3 seconds for lower, and 1.9 seconds for dump. The 721E XT has a rated bucket capacity of 3.5 cu yds (2.7 m³), a breakout force of 28,770 lbs (13,050 kg), and a maximum dump clearance of 9.4 ft (2.9 m). Key dimensions include a length with bucket on ground of 25.6 ft (7.8 m), a hinge pin height at max raise of 13.1 ft (4.0 m), a wheelbase of 10.7 ft (3.3 m), and a width over tires of 8.4 ft (2.6 m). The machine operates at 24 volts, with a 65-amp alternator, and has a total operating weight of 31,827 lbs (14,437 kg). Fluid capacities include 65 gal (246 L) fuel, 51 gal (193 L) hydraulic, and 9.8 gal (37 L) cooling system. The 721E XT is equipped with 20.5 R25 tires, a 24° rear axle oscillation, and a turning radius of 18.9 ft (5.8 m), ensuring excellent maneuverability and stability.
