the G976 All Wheel Drive Motor Grader.
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 front-
wheel Creep Mode for exceptional
fine-grading control.
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,
from highways to haul roads. Now with
advanced inching capability, Volvo AWD
performance raises the bar industry-wide
for starting with high blade loads from a
full stop.
Reaching a top speed up to 23.0 mph
(36,8 km/h) with the 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.
* 19.6 mph (31,4 km/h) with standard
HTE840 transmission
When fine-grading deadlines are tight,
G976 Creep Mode gets you to the finish
line first with ultimate precision and
effortless control.
Biggest is best
The G976 Motor Grader stands out
as the largest AWD machine in its class.
With a base weight of 40,500 lb
(18 370 kg) and its Volvo D9 engine
generating up to 265 hp (198 kW),
the G976 gives you the most of what
you’re looking for to get maximum
AWD performance.
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. 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
safely out of harm’s way. AWD monitoring
is integrated with the Contronics system,
ensuring extensive safeguards for lasting
reliability.
Ultimate precision
Operating at speeds under 2.5 mph
(4,0 km/h), the exclusive Volvo
Creep Mode allows the operator
to grade using only the hydrostatic
front-wheel drive; the rear tandems
roll freely behind to minimize
scuffing and rework.
Creep Mode is easily selected
via the transmission controller.
Ground speed 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.
