deeregraderDecember 10, 2013, Moline, Ill. — John Deere’s G-Series
Motor Graders now meet Tier 4 Final 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 several customer-inspired ideas to
better meet the needs of today’s operator.

“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

The G-Series still includes 12 models (670G/GP, 672G/GP,
770G/GP, 772G/GP, 870G/GP, 872G/GP) with net horsepower ranging from 220 to
287. Six of the units (those models ending in two: i.e. 872G) feature six-wheel
drive, enabling them to power through the toughest cuts with power flowing to
all wheels. Six-wheel drive gives operators increased traction, the ability to
get more work done in fewer blading passes and a 30-percent increase in blade


All motor grader models weigh the same as their Tier 4 Interim
predecessors. In addition, there is no sacrifice to visibility going from a Tier
4 Interim to Tier 4 Final engine. Visibility is solid to the sides and rear and
the operator can easily view the ripper while the machine is in motion. The
customer-favorite direct-drive transmission with event-based shifting continues
to offer smooth as silk gear and direction changes.

Operators don’t have to worry about diesel particulate
filter (DPF) cleaning as it still occurs automatically with no impact to machine
operation. Also, John Deere’s DPF has been tested to go up to 15,000 hours
before ash removal. 

Additionally, all models feature excellent total fluid
economy (diesel fuel and DEF).

As with all John Deere equipment, cooling package service
access is stress-free with a swing out fan door, pivoting coolers and standard
hydraulically driven cool-on-demand reversing fan that runs only when needed.
Finally, filters are located in an easy to access bank.

Customer feedback also drove John 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.

Operator control is a hallmark of the G-Series. Customers
continue to get a steering wheel and can choose from the console-mounted
low-effort industry standard control pattern (G models) or intuitive and
easy-to-use armrest-mounted industry standard fingertip controls (GP models).
If an operator specifies the fingertip controls, he'll still have a choice
between using lever steering and the ever-present steering wheel. Either way,
G-Series controls provide a smooth, predictable response and plenty of power
whether the application calls for heavy blading or fine grading.

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 John Deere motor graders come standard with John Deere
WorkSight™ suite of technology available for increasing uptime and productivity
while lowering operating costs.
