Technical Description

The John Deere 84 wheel loader is a compact, versatile machine designed for efficient material handling with a breakout force of 9,040 lbs (4,101 kg). It features a 1 cubic yard heaped bucket capacity and a bucket width of 6.9 ft (2 m), enabling effective loading tasks. The loader operates on a naturally aspirated Yanmar 4TN100 diesel engine with 211 cu in (3.458 L) displacement, delivering 55 hp gross and 52 hp net power. Hydraulic performance is optimized with a gear pump providing a flow capacity of 21.1 gal/min (79 l/min) and a relief valve setting of 2,500 psi, facilitating rapid dump (1 sec), lower (3.5 sec), and raise (5.4 sec) cycles. Dimensionally, the machine maintains a ground clearance of 1.1 ft (0.3 m) and has a height to the top of the cab of 9.5 ft (3 m). The loader’s length with the bucket on the ground is approximately 15.3 ft (5 m), with a 7.3 ft (2 m) wheelbase and a 6.6 ft (2 m) width over tires. Its turning radius stands at 12.5 ft (4 m), enhancing maneuverability in confined spaces. The transmission is a powershift type with three forward gears and one reverse gear, achieving a maximum forward speed of 17.7 mph (27 kph) and reverse speed of 7.1 mph (11 kph). Operating weight is 11,246 lbs (5,101 kg), supported by 17.5/65-20 tires and a rear axle oscillation of 16°. Fuel capacity is 15.3 gallons (57 liters), with separate fluid capacities for hydraulic, engine oil, transmission, cooling, and axle systems carefully specified to ensure reliable operation under demanding conditions.
