Deere updates motor graders to meet Tier 4 Final

For steering, G-Series operators can choose from the console-mounted industry standard control pattern or easy-to-use armrest-mounted industry standard fingertip controls.

Deere's G-Series motor graders have been updated to meet Final Tier 4 emissions standards with the implementation of a John Deere PowerTech EPA Final Tier 4/EU Stage IV engine. The engine update also allowed engineers to implement other updates.

"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 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 G-Series still offers 12 models with net power ranging from 220 to 287 hp (164 to 214 kW). Six of the units feature six-wheel drive, providing operators increased traction, the ability to get more work done in fewer blading passes, and a 30% increase in blade pull.

All the motor grader models weigh the same as their Tier 4 Interim predecessors and there was no sacrifice to visibility going from an Tier 4 Interim to Tier 4 Final engine. Visibility to the sides and rear allow the operator to easily view the ripper while the machine is in motion. The direct-drive transmission with event-based shifting offers smooth gear and direction changes.

DPF cleaning occurs automatically with no impact to machine operation. Also, after extensive testing it was found that the DPF can go up to 15,000 hours before ash removal.

Cooling package service access is made easier 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.

Customer feedback drove Deere to offer new LED worklights for better illumination around the G-Series models. Operators also have the ability to utilize satellite radio with Bluetooth capability. A new laminated cab glass option will be available in 2014 as well.

Operators of the G-Series continue to get a steering wheel and can choose from the console-mounted low-effort industry standard control pattern or easy-to-use armrest-mounted industry standard fingertip controls. If an operator specifies the fingertip controls, he or she will still have a choice between using lever steering and the ever-present steering wheel.

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.
