G900 MOTOR GRADERS
FROM THE GROUND UP
“The Voice of the Customer” is evident in every
element of the G900 design, from the manufacturing
process that builds it to the styling details that say
“It’s a Volvo”.
Productivity
The complete structural design of G900
Motor Graders is balanced to focus their
weight and power for optimum blade
down force and drawbar pull values.
Heavy-duty front axle
Purpose-built axle with high center
ground clearance; a minimum of
components ensures long life with
minimum maintenance; achieves sharp
steering angle for tight turning radius.
AWD
G976 models are equipped with three
easy-to-use operating modes: efficient
standard tandem drive, rugged All Wheel
Drive or Volvo exclusive Creep Mode for
the industry’s best fine-grading control.
Frame
Rugged front and rear frames, designed
for quick installation of a full range
of attachments.
Blade Lift System
Twin-gear direct-drive circle turn system
provides maximum strength to either
hold or to turn the moldboard smoothly
while moving under full load; wide-stance
blade lift cylinders provide fine grading
stability with the full range of mobility for
any application.

Service access
Easy Lift rear hood opens wide for easy
cleaning access to the radiator; cover
panels for the engine, hydraulic centre
and battery pack all open up fully for
ease of service; ground-level access to
all engine service points.
Volvo engine
Volvo D9 Tier 3/Stage IIIA engine
with V-ACT technology matched to the
powertrain with three power levels as
standard for optimum performance and
fuel efficiency.
Planetary rear axle with clutched
differential lock
Volvo APR90 axles with planetary
reduction final drives reduce loading on
tandem chains for maximum service life;
purpose-built differential with hydraulic
clutch lockup ensures maximum tractive
effort at the flick of a switch.
High capacity cooling system
Hydraulically driven, variable-speed
fan draws power only when needed;
optional auto-reversing feature reduces
maintenance, improves efficiency.

Serviceability
No daily greasing or weekly servicing is
required; optional 500-hour engine oil
change interval. Tandem and final drive
sight glasses make level checks fast
and easy. Large capacity hydraulic filter
extends change intervals and prevents
re-fill contamination as all top-up oils
must pass through the filter prior to
entering the hydraulic tank.
Contronics
Contronics display provides detailed
system status to the operator in real
time: records up to 25 points of interest
for service analysis through the exclusive
Matris system from Volvo.
Volvo transmission
The full power shift HTE840 and
optional HTE1160 transmissions were
developed expressly for motor graders.
Manual, optional Autoshift and Travel
modes optimize performance and fuel
economy. Standard shuttle shift feature
enables smooth shifting between forward
and reverse gears without using the
inching pedal.

Autoshift
Just select a target gear in the working
range and the transmission shifts
automatically through turns and grades,
as needed. Optional for HTE840
transmission, standard with HTE1160.
Operator-friendly cab
ROPS/FOPS enclosed operator
compartment lives up to every
expectation for a Volvo cab with
industry-leading comfort, safety and
efficiency. Ergonomic design includes
low-effort, short-throw levers; adjustable
pedestal with all most frequently used
operating controls centered in front
of the operator; unobstructed
wide-angle views to reduce operator
fatigue, increase productivity and
maximize safety.

Rear-view visibility
Interior and exterior mirrors combine for
a clear wide-angle view to the sides and
rear of the grader. Rear cab posts are
positioned to optimize operator visibility.
Fast refueling
Two-stage pop-up rear hood allows
quick, convenient access for ground level
refueling; lockable panels provide added
security on the job site or in the yard.
PDF Hydraulics
Proportional Demand Flow (PDF) is an
intelligent closed center, load-sensing
hydraulic system that delivers the exact
amount of hydraulic oil flow when and
where it is needed; variable displacement
axial piston pump provides excellent
multi-function control while conserving
fuel; minimal connections for high
reliability and low service requirements.
