The Case 821F XR wheel loader is a heavy-duty machine optimized for versatile loading and material handling tasks. It features a turbocharged 6-cylinder FPT F4HFE613X engine with a displacement of 411 cu in, delivering a gross power of 230 hp (172 kW) and net power of 211 hp (157 kW) at 1800 rpm, with a torque rise of 47% at 1300 rpm. The loader utilizes a 4-speed powershift transmission with 4 forward and 3 reverse gears, allowing a maximum forward speed of 22.8 mph (35 kph) and reverse speed of 15.2 mph (24 kph). The robust bucket has a heaped capacity of 4.2 cubic yards (3 m³), struck capacity of 3.6 cubic yards (2 m³), and a width of 10 ft (3 m), optimized for efficient scooping and dumping with a dump clearance at max raise of 11.3 ft (3 m). The hinge pin reaches a maximum lift height of 15 ft (5 m) with a reach of 4 ft (1 m) at max lift and dump. Hydraulic systems include a 63.5 gal/min (238 l/min) pump flow, with rapid cycle times including dump time of 1.2 sec, lower time of 2.5 sec, and raise time of 6.2 sec, all operating at a relief valve setting of 3625 psi. The wheel loader’s dimensions include a wheelbase of 11 ft (3 m), ground clearance of 1.4 ft (0 m), height to top of cab of 11.4 ft (3 m), and an overall length of 27.4 ft (8 m) with the bucket on the ground. It has an operating weight of approximately 39,716 lbs (18,015 kg) and runs on 23.5 x 25 L3 tires, providing stable traction and durability for demanding construction environments. The hydraulic system fluid capacity is 47 gallons (178 l), and fuel capacity is 76 gallons (288 l), supporting extended operation on site. Powered by 24 V electrical system with a 65 A alternator, this loader balances power, precision, and endurance for diverse heavy lifting applications.
