1997-2007 CASE 621F WHEEL LOADER

Technical Description

The Case 621F is a robust wheel loader featuring a 6-cylinder, 6.7L FPT F4HFE613W engine delivering 172 hp gross (152 hp net) at 2000 rpm, meeting Tier 4 emissions standards. It provides a maximum torque of 538.5 lb-ft, powering a 4-speed powershift transmission with LSD differentials front and rear, achieving up to 24 mph forward speed. The hydraulic system operates at 3625 psi with a 45.2 gal/min axial piston pump, supporting efficient cycle times of 11.9 seconds unloaded. Equipped with wet multi-disc service brakes and articulation steering, the 621F ensures reliable control and durability. The loader’s bucket capacity is rated at 4.5 cu yds (3 m³) heaped, with a breakout force of 25,425.9 lbs (11,533 kg). It offers a dump clearance of 9.5 ft (3 m) at max raise and a dump reach of 3.2 ft (1 m) at 45 degrees. Key dimensions include a wheelbase of 9.6 ft (3 m), overall length with bucket on ground of 24 ft (7 m), width over tires of 8.3 ft (2 m), and cab height of 11.2 ft (3 m). The machine weighs 26,711 lbs (12,116 kg) operationally. Fuel capacity is 65 gallons (246 L), supplemented by a 15.6-gallon DEF tank and 7.1-gallon cooling system capacity. The 621F offers strong rear axle oscillation (24°) for terrain adaptability. An alternator supplies 120 A at 24 V operating voltage. The design incorporates a cooling cube with a reversible fan to maintain high cooling efficiency, making it suited for dusty environments. Its heavy-duty axles and hydraulic capabilities deliver productivity and versatility for demanding construction and material handling applications.
