Three G-Series John Deere excavators—the 250G LC, the 350G LC and 380G LC—have advanced to Tier 4 Final engines that Deere says “maintain or reduce total fluid consumption,” figuring in both diesel fuel and diesel emission fluid.
The 250G LC has a 188-horsepower John Deere PowerTech PVSv6.8L engine, while the 350G LC and the 380G LC both use a 271-horsepower PowerTech PSS 9.0L engine.
The engines feature selective catalytic reduction technology and use a diesel particulate filter. According to Deere, the DPF can go up to 15,000 hours before ash removal. A larger hood improves access to the engine, emission reduction components and other components.
To improve serviceability, Deere moved its nine-pin diagnostic connector into the cab, reducing diagnostic testing time for equipment technicians. All fluid filter service points—including engine oil, fuel and hydraulic pilot oil filters—have been moved to ground level on the right side of the machine.
The 350G LC has a grade reference factory option, which Deere says reduces installation time by half. The option includes factory-mounted sensor mounting brackets welded to the boom, arm, dogbone (near the bucket), counterweight and mainframe, allowing immediate installation of the owner’s choice of grade reference systems, including Topcon, Trimble or Leica.
Another option is a programmable thumb attachment mode that allows operators to program oil flow for thumb attachments via the in-cab monitor.
Safety enhancements include new handrails and an optional light package that includes an under-the-hood light for greater visibility while servicing.
