TAKING GRADING PERFORMANCE
TO THE NEXT LEVEL.
Our motor graders have earned a reputation for exceptional control and grading
precision without a lot of extra effort. Inspired by thoughts and ideas from you,
our customers, our latest G-Series Graders take it to the next level. With more choices,
including our Customer Advocate Group-tested dual-joystick controls. Expanded
grade-control system options, including SmartGrade models with technology integrated
directly into the machine to deliver more accurate grading results. And a smaller, more
economical machine, the 620G. Existing models boast even more performance, along
with a host of proven features to help you boost productivity and maximize uptime
while lowering daily operating costs.
WHEN YOU ASK, WE LISTEN: THE 620G GRADER.

Our competitively priced 620G offers contractors, townships,
and municipalities the grader they’ve been asking for, with just
the right amount of power and fuel savings of up to 10 percent
over our larger models. It’s equipped — not stripped — with many
of the same features found on its larger siblings, including a
superior cooling package and ground-level service.

PRODUCTIVITY.
With their exceptional visibility, an LCD
high-visibility monitor, and smooth gate-
less shifting, it’s easy to see why G-Series
Graders have become a favorite on a wide
range of jobsites.
Exceptional view
All-around visibility is virtually unobstructed,
with a clear view to the heel and toe, and
behind the moldboard. You can even see the
area beneath the front axle, for increased
awareness of oncoming obstacles.
Store your stuff

Generous storage space includes numerous
overhead compartments, plus a place for
a beverage, cooler, cell phone, and other
carry-ons.
Lighting the way

Courtesy lighting stays on after machine
shutdown and then automatically turns
itself off, making it safer to exit the cab
after dark, while conserving battery power.
Easy-access park brake

Sealed-switch module provides push-button
control of key machine functions, including
the parking brake, for more convenient access
and easier operation.
LCD hi-vis monitor streamlines access

to vital data
LCD hi-vis monitor provides intuitive, push-
button access to vital machine information

All daily service points, including fueling and diesel exhaust fluid (DEF),
are grouped on the left side for quick and convenient ground-level access.
On the right side, maintenance personnel will appreciate the easy-access
engine oil, fuel, hydraulic, transmission, and differential filter bank.
Optional premium circle

This industry-leading design features a fully sealed bearing and pinion,
reducing operating costs while delivering 40-percent more torque and
15-percent more speed than a traditional circle. Contractors will benefit
from improved accuracy when using a grade-control system by no longer
having to compensate for wear in the circle. This is especially impactful
when coupled with the innovative John Deere SmartGrade™ system.
