Technical Description
The CASE 221D is a compact wheel loader designed for efficient material handling with a heaped bucket capacity of 1.4 cubic yards (1 m³) and a breakout force of 12,182 lbs (5,526 kg). It features a bucket width of 6.9 ft (2 m) and provides a dump clearance of 8.3 ft (2 m) at maximum raise. The loader has a hydrostatic transmission with two forward and two reverse gears, enabling a max speed of 12.4 mph (19 kph) in either direction. Its 57.5 hp (43 kW) F4M2011 four-cylinder engine delivers a torque rise of 9% at 1700 rpm, balancing power and efficiency.
Dimensionally, the 221D is 17.7 ft (5 m) long with a 7.4 ft (2 m) wheelbase, 6.3 ft (2 m) wide over tires, and stands 9.2 ft (3 m) tall to the top of the cab. It has ground clearance of 1.2 ft (0.4 m) and a hinge pin max height of 10.5 ft (3 m). Reach at max lift and dump is 2.6 ft (1 m), with a turning radius of 13 ft (4 m). Operating weight is approximately 11,793 lbs (5,349 kg), with a static tipping load of 8,874 lbs (4,025 kg).
The hydraulic system includes an open-centered pressure/flow compensated pump with a flow capacity of 17.4 gal/min (64 l/min), dump time of 1.1 sec, raise time of 5.5 sec, and lower time of 3 sec, operating at a relief valve setting of 3,335 psi. Fuel capacity is 26.4 gal (98 l), and the loader runs on a 12 V electrical system supported by a 55 A alternator. Tire size is 365/80 R20, and rear axle oscillation is 24°, enhancing maneuverability on rough terrain. Fluid capacities support durability and maintenance ease across cooling, engine oil, axles, and hydraulics.
