John Deere has upgraded three models on the G-Series excavator line. The models – 250G LC, 350G LC and 380G LC – are equipped with a powerful Final Tier 4 engine and are designed to 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 9.0L engine with horsepower at 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, which the manufacturer says helps to lower daily operating costs.
Diesel particulate filter (DPF) cleaning still occurs automatically with no impact to machine operation. John Deere’s DPF is designed to go up to 15,000 hours before ash removal.
Additionally, all models are designed to provide 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, which the OEM claims reduces 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.
