The 350 X4 LF (long-front) excavator for the U.S. and Canadian markets uses a 268-horsepower, Tier 4-F Isuzu engine (with no diesel particulate filter) designed to deliver up to 8 percent improved fuel economy in the base machine (compared with its predecessor). The 350 X4 LF features three engine modes: Speed Priority, Heavy, and Applied Power (with 13 speed settings to accommodate applications such as heavy lifting, fine grading, or leveling). The factory-designed-and-built long-front attachment provides a maximum digging depth of 46.25 feet.
A new, proprietary control valve with 30-percent larger hydraulic passage areas is designed to assist the 350 X4 LF base machine achieve up to 8-percent faster cycle times than its predecessor. Also, increasing the size of arm, boom, and auxiliary spools assists in reducing pressure losses and distributing oil more smoothly. The machine uses two electronically controlled Kawasaki variable-displacement, axial-piston pumps and single Kawasaki gear pump.
The cab for the machine is ROPS- and FOPS-certified and features a large, automotive-grade, high-back seat with lumbar support. Arm rests move proportionally with the console, allowing the distance and angle between joysticks and operator to remain constant as the seat is adjusted. The machine uses a 7-inch LCD color monitor that displays images (with selectable guidelines) from the standard rearview camera. Rear and side lights can also be added to the camera system.
The Wide Angle Visual Enhancement System (WAVES) can be added. The system includes three closed-circuit, high resolution cameras that provide a 270-degree viewing envelope.
Other notable new cab features include dual halogen cab lights (with optional LED lighting); redesigned joysticks with radio mute buttons; MP3 audio input, Bluetooth-enabled for hands-free communication; standard control-pattern changer, and increased storage areas.
Routine service points are positioned at ground-level, including sampling ports for engine and hydraulic oil. The RemoteCARE GPS-enabled telematics system allows 24/7 remote monitoring and security, says LBX, and the system tracks and records routine and major service intervals, as well as machine-health alerts. A six-year subscription is included at no extra charge.
