G900 MOTOR GRADERS
FROM THE GROUND UP.
“The Voice of the Customer” comes through
in every element of the G900 design, from the
manufacturing process that builds it to the styling
details that say “It’s a Volvo”.
Balance of power
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 Creep Mode, the original
hydrostatic front-wheel-only drive
setting the industry’s standard for
fine grading control since 1999.
Frame
Rugged front and rear frames, designed
for quick installation of a full range
of attachments.
Blade Control 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 D9B 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 and
reduces service needs.
Easy to keep
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.
