It features a 536.5 hp (400 kW) John Deere PowerTech PSX 6135 engine with 823.9 cu in displacement, compliant with Interim Tier 4 emission standards. The machine operates at 1600 rpm with a torque output of 1866.1 lb-ft and a torque rise of 23%, delivering robust and efficient power. Its hydraulic system includes a 99.9-gallon tank and an axial piston pump rated at 100.2 gal/min with 350 psi system pressure. This loader offers bucket capacities ranging from 8.6 to 10.1 cubic yards (6 to 8 m³), with a breakout force of 103,388 lbs (46,897 kg), capable of handling heavy materials efficiently. The machine’s operating weight is approximately 117,947 lbs (53,500 kg) and fuel capacity is 201.1 gallons (761 liters), supporting extended hours of operation. Dimensionally, the 944K stands 13.7 ft (4 m) tall to the top of the cab, with a maximum hinge pin height of 17.6 ft (5 m) and a reach at full lift and dump of 9.5 ft (3 m). Its length with the bucket on the ground is 38.4 ft (12 m), with a turning circle of 58.6 ft (18 m), a wheelbase of 14.8 ft (4 m), and a width over tires of 12.3 ft (4 m). It runs on standard 35/65 R33 tires. Braking is assured through wet multi-disc brakes on all wheels, hydraulically actuated, including an optional ride control system, and a wet multi-disc parking brake integrated with the transmission. The transmission is an A/C electric type supported by a 24V system and a robust 150A alternator, ensuring reliable driveline performance.
