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

July 8, 2014

Three John Deere excavator models, the 250G LC, 350G LC, and 380G LC, have been upgraded with Tier 4-Final engines and serviceability improvements.

The 250G LC features a 188-horsepower certified Tier 4-Final John Deere PowerTech PVS 6.8L engine. Both the 350G LC and 380G LC have a certified Tier 4-Final John Deere PowerTech PSS 9.0L engine generating 271 horsepower. Deere says DPF cleaning on the Tier 4-Final models occurs automatically with no impact to machine operation, and that the DPF can go up to 15,000 hours before ash removal.

The new G Series models also feature larger hoods for improved engine access. For convenience, the nine-pin diagnostic connector has been moved into the cab to reduce diagnostic testing time for technicians. Another improvement is 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 access.

In addition, a grade-reference-ready option for the 350G LC is available from the factory, reducing installation time. Sensor mounting brackets are welded to the boom, arm, dogbone, counterweight, and mainframe at the factory, enabling immediate installation 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 by using the monitor.
