JOHN DEERE 724K HIGH-LIFT WHEEL LOADER

Technical Description

The John Deere 724K High-Lift Wheel Loader features a turbocharged, charge air-cooled 6-cylinder 6090H engine delivering 264 hp (197 kW) at 1800 rpm, meeting Tier III emission standards. It has a displacement of 548 cu in (9 L) and a torque rise of 36%, providing strong performance for heavy-duty tasks. The loader's hydraulic system includes a variable axial piston pump with a flow capacity of 81.9 gal/min (307 L/min), system relief pressure of 3650 psi, and fast cycle times: dump time at 1.4 sec, lower time at 3 sec, and raise time at 5.5 sec. The bucket has a heaped capacity of 4.2 cubic yards (3 m³), a struck capacity of 3.7 cubic yards (2 m³), and a breakout force of 30,610 lbs (13,885 kg), supported by a 10 ft (3 m) wide bucket. The high-lift design allows a hinge pin max height of 14.7 ft (4 m) and dump clearance of 11 ft (3 m), enhancing material handling reach and efficiency. Dimensions include a length of 28.6 ft (9 m) with the bucket on the ground, a width over tires of 9.5 ft (3 m), height to top of cab at 11.1 ft (3 m), 1.4 ft (0.43 m) ground clearance, and a wheelbase of 10.7 ft (3.3 m). The operating weight is approximately 42,483 lbs (19,270 kg). The transmission is a countershaft powershift with 4 forward and 3 reverse gears, allowing max speeds of 22.2 mph (35 kph) forward and 15.1 mph (24 kph) reverse. The loader runs on a 24 V system with an 80 A alternator and carries 93 gallons (352 L) of fuel capacity. Tire size is 23.5 R25, with a turning radius of 18.6 ft (5.7 m) and rear axle oscillation of 26° for maneuverability in rough terrain. Fluid capacities include hydraulic system (29.1 gal), engine oil (7.4 gal), front and rear axle/diff (5.9 gal each), cooling system (9 gal), and transmission (6.4 gal). This robust configuration ensures high productivity and durability in demanding construction and material handling operations.
