STRONGER. TOUGHER.
FINER. SMARTER.
From heavy cutting to fine finishing, G900
Motor Graders work with grader operators
to perform every task efficiently, profitably.
Power on demand
With the G900 Motor Graders, Volvo
puts the keys to new levels of profitable
grader performance in your hands. What
you’ll notice first, is the power. Dig into
the job and Volvo digs in with you. Volvo
engines are renowned for high torque at
low RPMs, producing responsive, fuelefficient performance under all operating
conditions. When you call for power to
muscle through heavy overburden or
to hold and turn loads smoothly under
power, your Volvo G900 Motor Grader
comes through without hesitation.
Then there’s the touch
Highly responsive industry-standard
controls give skilled operators the sure
feel they need to do what they do
best. Wide stance blade lift cylinders
coupled with the low angle side shift
cylinder provide the most stable grading
platform in the industry. Heavy-duty
inching clutches and a powerful twingear direct-drive circle turn system
translate responsive control into precise
earthmoving results. You get more onepass finishes with cost-saving accuracy.
Precise and predictable
Volvo’s Proportional Demand Flow (PDF)
hydraulic system, balances flow between
all grading functions for consistent and
predictable implement control. The
G900 PDF hydraulic system is ideally
suited for all leading Automatic Blade
Control systems.
Gearing up for the bottom line
Volvo HTE transmissions, including
standard 8-speed and optional 11-speed
models, translate engine output into
intelligent power for faster, simpler duty
cycles. With selectable Manual, optional
Autoshift and Travel modes, your choice
of G900 Motor Graders offers power
and speed the way you want it, when you
want it. With the Volvo Autoshift mode,
you just select your gear and go. Your
Volvo HTE transmission does the rest to
get you up to speed in your working or
travel gear ranges quickly, economically
and smoothly. Volvo shuttle shift, a
standard feature on all Volvo Grader
transmissions, allows operators to make
effortless, forward-to-reverse shifts (and
vice versa) without stopping or using
the inching pedal. In jobs that require
frequent direction changes, shuttle
shifting means faster cycle times, less
fatigue and more work done at day’s end.

HTE1160: the fi rst 11-speed
grader transmission
With 11 forward speeds and 6 reverse,
the optional HTE1160 from Volvo
expands the gear range of the grader
to offer more control in the low-speed
range, more effi cient travel speed
in the high range, more precision in
the working range and exceptional
fuel effi ciency for every task.
The HTE1160 comes standard with
Volvo Autoshift, combining maximum
control with ultimate simplicity of
operation.
THE RIGHT TOOLS IN
THE RIGHT HANDS.
Volvo knows that you only get the best from
your machine when you get the best from your
operator – so we made experienced operators
part of our design team!
New ideas for old hands
Any tool is only as good as the person
using it. So when Volvo designed the
G900 Motor Graders, we started with
grader operators.
Making the best, better
Of course, we began with familiar,
industry-standard grader controls that
come easily to hand. But we gave
them a more responsive feel, plus loweffort levers and low-effort pedals to
make long hours easier. We devised an
interior layout that puts all operational
controls right where you need them.
Then surrounded it with the industry’s
most spacious compartment plus a
pedestal and seat that adjust to fit the
space to the operator. We added a Volvo
Contronic Monitoring System with a
smart display console that tells operators
everything they need to know about
the machine at a glance, in multiple
languages. But we also cleared exterior
lines of sight with exceptional floor-toroof visibility through the front, down to
the moldboard and close in to the sides.
Plus an unequalled rear view. A Volvo
Care Cab, in every sense.
Accurate grading
When site specifications call for precise
grade control, the Volvo G900 comes
through. Volvo worked with the leading
manufacturers of Automatic Blade
Control systems and developed the
G900 family with the contractor in mind.
The result – optional mounting brackets,
hydraulic and electrical connections
designed exclusively for machine control
systems. Even the pedestal head has
mounting locations for grade displays. So
no matter what brand of machine control
you currently use, the G900 is ready.
Know what you’re getting into
Open the cab door to your Volvo
Motor Grader – then, with automatic
illumination set for the steps and
handholds, you step up to the industry’s
easiest entry and exit. Inflows of outside
air are easily adjusted for maximum cab
pressurization or increased re-circulation
for fast warm-ups or cool downs. With
extensive noise and vibration suppression
designed into the cab and with the quietrunning Volvo engine behind, operators
spend the day in peace and quiet.
For hard-working people
Volvo works hard to keep operators at
their best all day long. A high capacity,
12-speed fan pushes fresh, doublefiltered air throughout the cab via 10
well-placed outlets. Window options on
the front and sides open wide for natural
ventilation or to minimize glare. High
capacity air conditioning and heating
systems keep temperatures comfortable
in any season. A wide range of comfort
amenities and ergonomic design features
make G900 Motor Graders a great place
to spend the working day.

protected from the severe load stresses
of ripping, scarifying, plowing, pushing
and snow clearing.
With attachments built and approved
by Volvo, G900 Motor Graders adapt to
year-round duties without compromising
design integrity.
MORE UPTIME.
LESS UPKEEP.
G900 Motor Graders reflect the Volvo commitment
to equipment that spends more time on the job, less
time in the shop.
Ease of service,
low maintenance demands
Start every day easy. G900 Motor
Graders carry on the Volvo approach to
maximum uptime: minimize the machine’s
need for service, then simplify the service
tasks it does require.
Sensible service design starts with easy
ground-level fueling and minimal grease
points, with no daily greasing required.
Sight glasses and level sensors
make daily checks virtually effortless.
Exclusive long-wearing Duramide™ circle
support bearings prevent metal-to-metal
contact to keep critical tolerances tight
and the circle turning smoothly.
Changing the Duramide bearings on
the moldboard slide rail is fast and easy
- simply remove 4 bolts and slide the
lower sleeve bearing out!
The G990 top and bottom moldboard
rails are shim-adjustable to maintain tight
blading tolerances.
Open for business
With an “Easy Lift” rear hood, gull-wing
side panels and removable hydraulic tank
cover, G900 Motor Graders are unrivaled
for easy routine service. The complete
rear cowling opens wide to allow quick,
thorough service checks, then back to
work quickly.
Keep it simple, smart
The hydraulic system is designed for fast
manual or pressure fills through the top
of the tank. All added fluids must pass
through a large, full flow return filter to
prevent accidental contamination in the
reservoir that could lead to down time.
Hoses are routed over the surface of the
frame for simple inspections.
The Volvo cooling module eliminates
stacked cores. Instead, multiple
cooling cores are positioned to receive
fresh, cool ambient air continuously.
A thermostatically controlled, hydraulically
driven fan maximizes available power
and fuel savings. An auto-reversing
cooling fan option allows continuous
self-cleaning to further improve cooling
performance and reduce service needs.
CareTrack:
Everything you want to know
All G900 Motor Graders can be equipped
with CareTrack, a remote monitoring
system developed by Volvo Construction
Equipment. The system collects
machine data which can be wirelessly
transferred to a computer. The machine
data displayed remotely includes:
machine position, operating hours, fuel
consumption, alarms and more*.
CareTrack makes it easier to plan for
service and reduces costly downtime.
It also helps eliminate unauthorized
usage and theft by using virtual fences
to restrict the operating area of the

V-ACT
The new generation of D9B engines
with Volvo Advanced Combustion
Technology (V-ACT) is tailored for grader
applications, designed to run cleanly
and effi ciently without the extra service
requirements of additional equipment or
after-treatment of exhaust gases.
ALL-PURPOSE ALL WHEEL DRIVE.
The All Wheel Drive G976 Motor Grader is
unmatched for pure versatility.
The drive to succeed
When you’re looking for excellence in
every grader task, Volvo All Wheel Drive
is the grader that gets you there.
Having a Volvo AWD is like having three
drive systems in one: a highly efficient
4-wheel tandem drive, a powerful
6-wheel drive plus the exclusive Volvo
Creep Mode, the industry’s original
hydrostatic front-wheel-only drive for
exceptional fine-grading control.
A firm footing for AWD
The Volvo AWD system is built around
two variable displacement axial piston
pumps feeding direct drive wheel motors:
no planetary gear reductions, no clutch
packs. Pump displacement is controlled
in response to the aggression switch
setting for precise wheel power control.
The system requires no flow divider valve,
providing efficient transmission of power
from the pumps to the motors with
minimal pressure drops.
Hydraulic hoses for the front wheel
drive are positioned high up, safely
out of harm’s way. AWD monitoring is
integrated with the Contronics system,
ensuring extensive safeguards for
lasting reliability.
Biggest is best
The G976 Motor Grader stands out as
the largest AWD machine in its class.
With a base weight of 43,650 lb
(19 800 kg) and its Volvo D9B engine
generating up to 277 hp (207 kW),
the G976 gives you the most of what
you’re looking for to get maximum AWD
performance.
When the going gets tough
Volvo All Wheel Drive can deliver up to
8,500 lb (3 855 kg) of additional rim
pull at the front wheels for increased
blade loads. With 16 selectable levels
of aggression, operators can match
traction to any operating conditions.
With high start-up torque capability,
Volvo AWD performance raises the bar
industry-wide for starting high blade
loads from a full stop.
Reaching a top speed up to 23.0 mph
(36,8 km/h) in 10
optional* HTE1160 transmission in AWD
mode, the G976 is today’s top-of-the-line
for optimum snow-clearing operations or
any high speed AWD application.
When fine-grading deadlines are tight,
G976 Creep Mode gets you to the finish
line first with ultimate precision and
effortless control.

HTE840 transmission
Ultimate precision
Proven on job sites since 1999,
Volvo Creep Mode sets today’s
benchmark for fi ne-grading control
by allowing the operator to grade
using only the hydrostatic frontwheel drive; the rear tandems roll
freely behind to minimize scuffi ng
and rework. Creep Mode is easily
selected via the transmission
controller. Operating at speeds
under 2.5 mph (4,0 km/h), the
front-wheel-only drive is controlled
simply by pressing the accelerator
pedal. Creep Mode allows extremely
smooth starts and stops, eliminating
ridges often left by the moldboard in
a conventional grader. The result is
more precise passes in less time to
complete the job.

Volvo Construction Equipment is different. It’s designed, built
and supported in a different way. That difference comes from
an engineering heritage of over 170 years. A heritage of
thinking first about the people who actually use the machines.
About how to help them be safer, more comfortable, more
productive. About the environment we all share. The result
of that thinking is a growing range of machines and a global
support network dedicated to helping you do more. People
around the world are proud to use Volvo. And we’re proud
