Deere Updates Motor Graders to Tier 4 Final

December 10, 2013

John Deere’s G-Series motor graders will implement a John Deere PowerTech EPA Final Tier 4/EU Stage IV engine, allowing the units to meet Tier 4 Final emissions standards.

"Updating the G-Series engines to Final Tier 4 allotted us the opportunity to talk with customers in more detail about what they liked and didn't like with the G-Series design," said Mike Ackerman, product marketing manager, motor graders, John Deere Construction & Forestry. "They wanted an emissions solution with no compromises, better all-around lighting, a more modern radio, an improved rear view camera with a dedicated monitor and a few upgraded cab features. We delivered on these with these new G-Series motor graders."

The 12 models of the G-Series include 670G/GP, 672G/GP, 770G/GP, 772G/GP, 870G/GP and 872G/GP. All Final Tier 4 models will have the same weight as the models with Interim Tier 4 engines.

The new G-Series models will now offer new LED worklights for better illumination, as well as the option for satellite radio with Bluetooth capability. A new laminated cab glass option will also be available in 2014.

There is no sacrifice to visibility going from an Interim Tier 4 to Final Tier 4 engine; the operator can easily view the ripper while the machine is in motion. The direct-drive transmission with event-based shifting continues to offer smooth gear and direction changes.

Diesel particulate filter (DPF) cleaning still occurs automatically with no impact to machine operation. 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).

Cooling package service access is simplified, with a swing out fan door, pivoting coolers and standard hydraulically driven cool-on-demand reversing fan that runs only when needed. Filters are located in an easy to access bank.

Customers can choose from the console-mounted low-effort industry standard control pattern (G models) or armrest-mounted industry standard fingertip controls (GP models). With the fingertip controls, operators still have a choice between using lever steering and the steering wheel. 

John Deere’s “open-architecture” design lets customers employ their favorite brand of grade-control system. GP models come factory equipped with bulkhead connectors, sensor mounts, electrical wiring harnesses, integrated controls and exclusive moldboard mast mounts. Machines can also be factory-installed with Topcon 3D-MC2 grade control system for faster availability and the ability to finance the system with the grader purchaser. All GP models come standard equipped with automated cross-slope.

All Deere motor graders come standard with the John Deere WorkSight comprehensive suite of technology.
