1990-2021 JOHN DEERE 824K Z-BAR WHEEL LOADERS

Technical Description

The John Deere 824K Z-Bar Wheel Loader is a heavy-duty machine designed for robust performance and efficiency in material handling. Powered by a 6-cylinder, turbocharged, charge air-cooled John Deere 6135H engine, it delivers a net power of 333 hp (248 kW) at 1600 rpm with a notable torque rise of 59%, ensuring strong lugging ability and quick responsive power. The loader features a breakout force of 41,678 lbs (18,905 kg), providing exceptional digging and lifting strength. Its bucket has a heaped capacity of 6.1 cu yds (5 m³) and a struck capacity of 5.3 cu yds (4 m³), with a width of 10.8 ft (3 m), suitable for large volume loading tasks. Dimensionally, the 824K Z-Bar measures 30.4 ft (9 m) in length with the bucket on the ground, 10.1 ft (3 m) wide over tires, and 11.5 ft (3 m) in cab height. The hinge pin reaches a maximum height of 14.7 ft (4 m), and dump clearance at max raise is 10.5 ft (3 m). The ground clearance is 1.6 ft (0.5 m), and it has a wheelbase of 11.4 ft (3.5 m). The machine operates at a weight of about 57,783 lbs (26,210 kg), providing stability for heavy lifting operations. Hydraulically, it employs two variable displacement, load-sensing axial piston pumps delivering a flow of 135.6 gal/min (511 L/min), with cycle times of 5.9 seconds raising, 1.3 seconds dumping, and 2.5 seconds lowering the bucket. Operating pressure is set at 3650 psi. The transmission is a powershift countershaft type with 4 forward and 3 reverse gears, reaching a max forward speed of 24.9 mph (39 kph) and reverse up to 18.8 mph (29 kph). It incorporates a robust 24 V electrical system with an 80 A alternator and large fluid capacities supporting engine oil (10.1 gal), hydraulic fluid (42.1 gal), and fuel (124.1 gal), ensuring long operational duration and reliability in demanding applications. Tire size is 26.5 R 25, and the rear axle oscillates 26° for enhanced maneuverability on uneven terrain. This combination makes the 824K Z-Bar a powerful and versatile loader for heavy construction, mining, and industrial material handling tasks.
