LS-4300 C II Link-Belt excavator specs & Dimensions (1989 - 2023)

Mode Select

The mode selection system enables the operator to program the machine's power to the job application. The operator can select three modes according to the job conditions: H - Heavy Duty (digging in rocky conditions, dense material). 100% of the engine horsepower is made available for maximum power in the ditch. S - Standard (general excavation, loading trucks). 85% of the engine horsepower is made available to match power to the application and conserve fuel. L - Lifting (setting pipe, placing manholes). 65% of the engine horsepower is made available for jobs where accuracy and safety are valued over speed.

One Touch Decelerator

Increased fine control and fuel savings can be realized by using the exclusive fine control selection system. The operator can select from three engine idle speeds: 1000 rpm for fine inching, 1300 rpm for setting pipe, or 1500 rpm for fine grading. At the touch of a button, the engine will automatically return to high idle for power and speed when the operator is ready to return to normal digging.

SCM Monitor

The SCM (Service Check Maintenance) monitor advises the operator on all critical machine functions at a glance. Both audio and visual warnings indicate low water, high engine temperature and engine oil pressure. Indicator lights monitor mode selection system, fine control, swing brake, glow plug, air intake restriction, two-speed travel, air system, battery fluid level and free swing mode. Three bar gauges monitor fuel level, water temperature and hydraulic oil temperature.

Computer Aided Power System (CAPS)

The LS-4300 C-Series II CAPS hydraulic system with its variable volume/pressure compensated piston pumps and pilot controls provide smooth operation and maximum horsepower utilization. Fuel consumption is minimized by the digging and fine control mode selection systems and the integral Automatic Pump Destroking (APD) feature. Pump flows are automatically reduced to minimum output when control levers are in the neutral position. These systems save fuel and eliminate wasted engine and hydraulic power plus extend component life. The CAPS system enables the operator to simultaneously operate the swing, travel and attachment for full function control of the machine. This feature plus the automatic high speed arm and boomhoist result in fast cycle times and increased production.

Single Pedal Travel

A single pedal travel system allows the operator to engage both tracks at the same time using only one pedal. This keeps the machine in line with the ditch and provides safety and ease in loading/unloading the machine for transport.

Free Swing Control

The standard free swing feature allows the operator to disengage the swing brake, providing precise control and added safety when swinging a load. The swing brake can be engaged to eliminate the upper from coasting when working on a side hill. Additionally, the swing brake automatically applies 4 to 5 seconds after the control lever is returned to neutral.

Control Panel

Conveniently located in the right side control console are ignition switch, engine throttle, service monitor check button, engine stop button, control shut down switch, cushioned attachment control switch, AM-FM radio and switches for wiper, heater fan, working lights, selectable fine control, digging mode select, manual throttle and emergency bypass switches.

Maximum Window Area

The C-Series II cab is designed to provide maximum visibility for the operator with its full view front window and lower right and left hand windows.

Lift-up Arm Rest

Left arm rest lifts up out of the way providing outstanding operator ease in entering or exiting cab. For safety, when arm rest is raised all control functions become inactive.

Cushioned Attachment Control

Mounted in the right side console is the cushion attachment control switch. In this mode, cushion valves in the pilot control system keep boom and arm cylinder movements smooth for shock-free operation. This adds up to added safety during precise lifting applications and reduced operator fatigue.
