John Deere Reveals 250G LC, 350G LC, and 380G LC Final Tier 4 Excavators

 


348Over the coming months, there will many announcements about the introduction of Tier IV Final engines as the deadline for compliance gets ever closer. The latest company to make such an announcement is John Deere.

Three of the four tracked excavator  models in the 25 - 40 tonnes class  – 250G LC, 350G LC and 380G LC  - are now equipped with a  Final Tier 4 engine to meet the strictest emissions standards.  The other model,  the 290G LC, will be updated later.  Contractors Plant & Equipment was unable to get a date from the company.

Although there is a cost to the customer for this regulatory requirement, the resulting  higher productivity, increased uptime, and lower daily operating costs that the new technology makes possible means that the cost is soon recovered.

Contractors World understands that the higher purchase cost can be recovered within the first 12 month depending, of course, on how much the machine is used.  This typically applies to all companies who are required to upgrade to the latest cleaner engines that Tier IV Final standards deliver.

“When developing the new G-Series Final Tier 4 models, we wanted to maintain the  features that John Deere excavators are known for while evolving the line to reflect the needs and standards of the industry,” said Mark Wall, excavator product marketing manager, John Deere Construction & Forestry.

“By adding a rangel of new features, as well as design and functionality improvements, we are able to offer customers an excavator that increases performance and productivity, without compromising on sightlines and service access.”

The 250G LC features a 188 hp certified Final Tier 4 John Deere PowerTech PVS 6.8L engine.   The 350G LC and 380G LC feature a Final Tier 4 John Deere PowerTech PSS 9.0L engine with horsepower at 271 hp (350G LC) and 271 hp (380G LC).

Operators do not have to worry about diesel particulate filter (DPF) cleaning as it  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 is 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.

An 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.
