350D/HM300 Haul Truck

Full Specifications

Limited-slip differentials (250D/300D), controlled traction differentials (350D/400D), and transfer case diff lock provide a traction
boost in poor underfoot conditions.
Excellent payload-to-weight ratio means more of your fuel dollars
are spent moving material, not the machine — decreasing your
cost per ton.
Best-in-class transmission retarder slows the truck when the operator backs off the accelerator. For superior braking and increased
service-brake life.
High-pressure common-rail fuel injection (250/300) and electronic
unit injection (350/400) provide high injection pressure even at
low engine speeds for improved cold-weather starting, low-speed
response, and reduced emissions.
Short-sloped front end provides an industry-best approach angle
that allows these ADTs to attack steep terrain.
Inter-axle differential delivers equal torque to each axle on favorable footing. When conditions get ugly, engage the diff locks to
deliver torque to the tires that can best use it.
