Technical Description

The CASE 721C is a robust wheel loader engineered for demanding construction and material handling tasks. Powered by a turbocharged 6-cylinder Cummins 6T-830 engine, it delivers 152 hp (113 kW) net power at 2,200 rpm and 165 hp (123 kW) gross power, with a maximum torque of 525 lb-ft at 1,300 rpm and a 41% torque rise for enhanced performance. The loader features a 4F/3R proportional transmission with electronic control module, torque-sensing autoshift/manual shift, and modulation for smooth, efficient operation. With an operating weight of 29,630 lbs (13,440 kg) and a static tipping weight of 23,221.3 lbs (10,533 kg), it provides excellent stability and lifting capacity. The hydraulic system includes a dual vane-type tandem pump, offering a flow capacity of 18.6 gal/min (68 l/min) and a relief valve setting of 2,775 psi, enabling fast cycle times: 5.4 seconds to raise, 5.1 seconds to lower, and 1.8 seconds to dump.
