Product Features
The CX300C’s Advanced Hydraulic System uses five energy-saving functions to balance performance with efficiency. CASE’s Boom Economy Control, Auto Economy Control, and Swing Relief Control automatically fine-tune hydraulic power, delivering strong breakout force with reduced fuel burn. Pump torque control ensures smooth performance under load while maintaining engine stability, giving operators the power and precision to move more material with less effort. Inside the cab, the CX300C offers one of the most comfortable working environments in its class. The ROPS and FOPS certified cab is quiet and spacious, fitted with a fully adjustable air suspension seat, ergonomic joystick controls, and a large seven-inch LCD display for real-time performance data and diagnostics. Ground-level access to all service points, extended maintenance intervals, and CASE’s EMS bushings with 1,000-hour greasing intervals all help keep downtime low and productivity high.
High-Performance Isuzu Engine
The CX300C is powered by a proven 6-cylinder ISUZU Tier 3 engine that produces 212 kW and 1020 Nm of torque. The high-pressure common rail fuel system and turbocharged intercooler deliver responsive power and consistent torque, even under heavy load. Designed for strength and reliability, it delivers smooth, stable performance across demanding excavation, lifting, and loading tasks with excellent fuel economy.
