ALL-PURPOSE ALL WHEEL DRIVE.
The All Wheel Drive G976 Motor Grader is
unmatched for pure versatility.
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 Volvo
Creep Mode, the industry’s original
hydrostatic front-wheel-only drive for
exceptional fine-grading control.
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. Pump 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 high up, safely
out of harm’s way. AWD monitoring is
integrated with the Contronics system,
ensuring extensive safeguards for
lasting reliability.
Biggest is best
The G976 Motor Grader stands out as
the largest AWD machine in its class.
With a base weight of 43,650 lb
(19 800 kg) and its Volvo D9B engine
generating up to 277 hp (207 kW),
the G976 gives you the most of what
you’re looking for to get maximum AWD
performance.
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.
With high start-up torque capability,
Volvo AWD performance raises the bar
industry-wide for starting high blade
loads from a full stop.
Reaching a top speed up to 23.0 mph
(36,8 km/h) in 10
th gear 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.
When fine-grading deadlines are tight,
G976 Creep Mode gets you to the finish
line first with ultimate precision and
effortless control.
* 19.6 mph (31,4 km/h) with standard
HTE840 transmission
