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, Volvo Motor
Graders offer 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 gear ranges
quickly, economically and smoothly.
The innovative shuttle shift feature
standard on all transmissions ensures
the industry’s quickest, simplest duty
cycles ever. Shuttle between selected
forward and reverse gears in a single
smooth motion without clutching, without
pausing, for easy effortless control and,
best of all, less fatigue at the end of a
long day.
HTE1160: the first 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
efficient travel speed in the high
range, more precision in the working
range and exceptional fuel efficiency
for every task. The HTE1160 comes
standard with Volvo Autoshift,
combining maximum control with
ultimate simplicity of operation.
EVERY DAY BEGINS WITH
SAFETY FIRST
To make your work environment more productive,
Volvo starts by making it safe and comfortable.
A healthy workplace
Open the cab door to your Volvo Motor
Grader – with automatic illumination set
for the steps and handholds, you step up
to the industry’s easiest entry and exit.
A sloped rear wall provides extra headroom and more side window visibility. A
constant flow of fresh double-filtered air
fills the cab from 10 well-placed outlets.
Inflows of outside air can be adjusted for
maximum cab pressurization or increased
re-circulation for fast warm-ups or cool
downs. High capacity air conditioning
and heating systems keep temperatures
comfortable in any weather. Windows to
the front and sides open wide for natural
ventilation. Spend the day in peace and
quiet with extensive noise and vibration
suppression designed into the cab and
the quiet-running Volvo engine behind.
What you see
Expansive glass areas provide
exceptional floor-to-roof visibility through
the front of the grader, down to the
moldboard and close in to the sides.
The rear view is equally clear with
sculpted side posts opening the line of
sight over the shoulder, complemented
by a unique arrangement of interior and
exterior mirrors. From the operator seat,
all essential operational controls and
displays are directly front and center on
the pedestal. Environmental and service
controls are also packaged together
conveniently in the right-hand console.

ASSURED QUALITY
LIFELONG RELIABILITY
Volvo Motor Graders set the standard
worldwide for performance you can bank on
every day, for every job.
Volvo D9 engine
Real world flexibility
G900 Motor Graders are purposebuilt with a true tool-carrier frame
designed to withstand the rigors of
all-season service.
The full perimeter rear frame
provides effective support for
rear and side attachments while it
protects powertrain components
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.
All in the family
Built on a solid foundation of fieldproven Volvo components including the
D9 engine, Volvo transmissions, the
Contronics monitoring system and many
service items, G900 Motor Graders have
been engineered with years of reliable
service already built in.
Keep on rolling
Trust Volvo G900 Motor Graders for a
long life of hard work.
The modular Volvo assembly process
and precise welding technology
ensure uniform end-to-end strength
in all structural components for lasting
durability. Exclusive DURAMIDE
support bearings prevent metal-tometal contact to keep critical tolerances
tight and the circle turning smoothly.
Innovative design of the articulation
joint achieves a robust assembly that
simplifies and protects the routing for
hydraulic lines.
Volvo APR planetary reduction axles
with operator-controlled hydraulic
clutch differential lock deliver power to
the ground efficiently while ensuring
dependable long-life service. In every
detail, G900 Motor Graders reflect the
Volvo commitment to lasting value.

LESS WORK
MORE PRODUCTION
The Volvo approach to servicing lets you spend
more time working on the job, less time working
on the machine.
Ease of service,
low maintenance demands
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.
Start every day easy. Sensible Volvo
service design starts with fueling and all
engine service points accessible from
ground-level, with minimal grease points
and no daily greasing required. Sight
glasses and level sensors make daily
checks virtually effortless.
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
With their modular powertrain design
concept, G900 Motor Graders simplify
maintenance on major components and
allow new levels of flexibility for optimal
service scheduling.
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.
Everything you want to know
The G900 electronic monitoring
system provides a familiar window to
the standard Volvo Contronics system,
providing a complete record of grader
functions to help operators, owners and
service technicians achieve optimum
machine performance.
V-ACT
The new generation of D9 engines
with Volvo Advanced Combustion
Technology (V-ACT) is tailored for
grader applications, designed to run
cleanly and efficiently without the
extra service requirements
of additional equipment or
after-treatment of exhaust gases.
