• a safe and comfortable operator
environment
• long lasting reliability
• unmatched ease of serviceability with
low maintenance demands
This Volvo Motor Grader offering includes
three highly efficient and versatile
models, all using the field-proven Volvo
D9 engine. The result is a selection of
graders with outstanding power, torque
and fuel efficiency: the 41,660 lb
(18 900 kg) G970 tandem drive, the
43,650 lb (19 800 kg) G976 All Wheel
Drive (AWD) model and, at 48,720 lb
(22 100 kg), the largest machine in the
Volvo Motor Grader family: the G990
tandem drive.
Quality with confidence
No family of motor graders anywhere
has been subject to more rigorous
testing than Volvo G900 Motor Graders.
By listening to customer needs and
responding with design innovations
like the industry’s first 11-speed grader
transmission with autoshift, the Volvo
continuous improvement program
leads the G900 family to ongoing
quality leadership.
At home in the Volvo fleet
From end-to-end, from the ground up,
the G900 Motor Graders are fit and
finished to take their place in your fleet.
Design details and their renowned
Volvo Care Cab provide a familiar work

and operators of any Volvo machine.
Care for the environment, one of the
Volvo core values, is reflected in the
environmental performance of the G900
Motor Graders. The G900 family meets
EU Stage IIIA and US Tier 3 Emission
Regulations as well as EU noise
standards. Volvo engineering minimizes
whole body vibration to maximize
operator productivity.
For grader operators and owners
everywhere, the G900 Motor Graders
means a new standard in grading
performance and productivity.

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.
