The Link-Belt 300 X3 excavator is a heavy-duty hydraulic excavator equipped with a robust Isuzu AL-6HK1X engine delivering a net power of 207 hp (154 kW), providing strong and efficient performance for a variety of construction and earthmoving tasks. It operates at a weight of 65,918 lbs (29,900 kg), enabling optimal stability and digging capacity. The machine’s hydraulic system features two Kawasaki variable-displacement axial-piston pumps and one Kawasaki gear pump, designed for efficient power delivery while keeping engine rpm low for fuel efficiency and smooth operation. The 300 X3 offers four selectable working modes—including Heavy, Applied Power, and others—that allow operators to fine-tune engine rpm settings and hydraulic output to match specific applications such as heavy lifting, fine grading, or pipeline installation. This excavator has a maximum digging depth of 23 feet 4 inches (7.10 meters), a maximum reach at ground level of approximately 34 feet 3 inches (10.50 meters), and a maximum dig height near 33 feet, supporting a broad range of excavation needs. Its hydraulic and electronic control systems include features like one-touch and auto idle functions to conserve fuel, an auto-power boost for peak performance, a neutral safety start, an anti-theft password protection system, and an on-board diagnostic system with memory and service reminders. Travel speeds range from 0.2 to 3.4 mph, with a drawbar pull of 52,380 lbf (233 kN) and gradeability up to 70% (35 degrees), ensuring strong mobility in challenging terrain. Overall dimensions are approximately 34 ft 3 in length, 11 ft 2 in width, and 10 ft 8 in height for transport and jobsite maneuverability.
