John Deere upgraded three models of its G-Series excavator line — the 250G LC, 350G LC, and 380G LC. The units are equipped with a final Tier 4 engine and meet the strictest emissions standards.

The 250G LC features a 188 hp certified final Tier 4 John Deere PowerTech PVS 6.8L engine. Both the 350G LC and 380G LC boast a certified final Tier 4 John Deere PowerTech PSS 9L engine with 271 hp (350G LC) and 271 hp (380G LC). The improved final Tier 4 technology enabled John Deere to maintain or reduce total fluid consumption, helping to lower daily operating costs.

Operators don’t have to worry about diesel particulate filter (DPF) cleaning as it still occurs automatically with no impact to machine operation. Also, after extensive testing, John Deere’s DPF can go up to 15,000 hours before ash removal. 

Additionally, all models feature excellent total fluid economy (diesel fuel and DEF).

To increase uptime, John Deere designed the new G-Series models with a larger hood for improved engine access. For convenience, the nine-pin diagnostic connector was moved into the cab to reduce diagnostic testing time for technicians. Other improvements include a single side ground level fluid filter service, which moves the engine oil, fuel, and hydraulic pilot oil filters to ground level on the right side of the machine and adds a service door for easy access to change filters.

A grade reference ready option for the 350G LC is available from the factory, reducing installation time by half. Sensor mounting brackets are welded to the boom, arm, dogbone, counterweight, and mainframe at the factory, enabling immediate install of Topcon, Trimble, Leica or other grade reference systems. A programmable thumb attachment mode is also available and enables operators to program oil flow for thumb attachments with the monitor.

New handrails help maintain contact when climbing the upper structure to service the engine, improving service accessibility and security. The optional light package now includes a hood light to provide greater visibility to the engine compartment to easily see daily service points. The hood light is ideal for customers who work in dark or low light environments, or those who run multiple shifts and may need to conduct late-night fuel and lube operations.
