JOHN DEERE 444J POWERLLEL PIN-ON WHEEL LOADER

Technical Description

The John Deere 444J Powerllel Pin-on Wheel Loader is a robust mid-sized loader equipped with a turbocharged, air-cooled 4-cylinder 4045H engine, delivering 119 hp at 2200 rpm and a torque rise of 32% at 1400 rpm. It features a 2.5 cubic yard heaped capacity bucket with a breakout force of 16,233 lbs, an 8.4 ft bucket width, and a maximum hinge pin height of 12 ft, providing efficient material handling and reach. The loader’s hydraulic system employs a variable axial piston pump with a 37 gal/min flow and a relief valve set at 3600 psi, enabling fast cycle times: 5.5 seconds for raising, 1.1 seconds for dumping, and 1.9 seconds for lowering the bucket. The machine’s dimensions include a ground clearance of 1.3 ft, a wheelbase of 9 ft, and an overall length of 22.8 ft with the bucket on the ground. It rides on 17.5 R25 tires and has a turning radius of 15.5 ft, suitable for maneuvering in confined areas. The 24-volt electrical system supports an 80 amp alternator. Fuel capacity is substantial at 65 gallons, with hydraulic fluid capacity of 26 gallons. Transmission is a countershaft type PowerShift with four forward and three reverse gears, allowing a maximum forward speed of 23.4 mph and reverse speed of 15.7 mph. Operating weight is approximately 23,926 lbs, providing stability supported by a rear axle oscillation of 24 degrees. This loader balances power, hydraulic efficiency, and maneuverability for versatile construction and material handling tasks.
