1999-2003 CASE 121E WHEEL LOADER

Technical Description

The CASE 121E Wheel Loader is a compact and versatile machine designed for efficient earthmoving tasks. It features a Tier 2 certified F4M2011 4-cylinder diesel engine with a displacement of 190 cu in, delivering a gross power of 59 hp (44 kW) and net power of 57 hp (43 kW) at 2400 rpm. The machine offers a breakout force of 9,337 lbs (4,235 kg) and is equipped with a hydrostatic transmission providing two forward and two reverse gears, enabling a maximum speed of 12.4 mph (19 kph) in both directions. The loader’s rated bucket capacity is 1.18 cubic yards (1 m³) heaped and 0.9 cubic yards struck, with a bucket width of 6.8 ft (2 m). It boasts a dump clearance at maximum raise of 8.4 ft (2.6 m) and a reach at max lift and dump of 2.8 ft (0.85 m), enhancing loading efficiency. The wheelbase measures 7.4 ft (2.25 m), while overall length with the bucket on the ground is 18 ft (5.49 m), and width over tires is 6.3 ft (1.92 m). Operating weight stands at 10,849 lbs (4,921 kg), supported by 14.5x20 tires and rear axle oscillation of 24°, improving ground contact and stability. Hydraulic system pump flow capacity is 17.7 gal/min (64 l/min) with pressure relief set at 3,916 psi, enabling fast bucket cycle times (raise time: 6 sec, dump time: 1 sec, lower time: 3 sec). Key operational fluids include 26.4 gal (98 l) fuel capacity, 17.7 gal (64 l) hydraulic fluid capacity, and 2.6 gal (8 l) engine oil capacity. Its compact dimensions combined with strong lift performance make the CASE 121E ideal for construction, landscaping, and material handling in confined spaces.
