Front Suspension. New front suspension

oscillates ±6° to provide a smoother

ride, allowing the operator to travel

faster over rough terrain and softening

impact loads on structures and

components.

Rear Suspension. Features a walking

beam geometry that provides a stable

ride for excellent load retention.

Traction Control. The traction control

system is comprised of a wet clutched

inter-axle differential and wet clutched

cross-axle differentials. All differentials

can be engaged and disengaged on-the-

go for maximum versatility. When used

together, the differentials provide 100

percent driveline locking.

Inter-Axle Differential Lock. Modifies

torque distribution to give a fixed 50/50

torque split between tractor and trailer

for excellent traction in poor underfoot

conditions and on grades. It is operated

by a switch in the footrest.

Cross-Axle Differential Locks. Provides

full driveline locking – all three axles

and all six wheels – for maximum

performance in the most adverse

conditions. Acts in unison with the

inter-axle differential lock when the

footswitch is actuated and the dash-

mounted switch is selected.

Oil-Immersed, Oil-Cooled Brakes.

Multi-plate oil-immersed brakes are

fitted to both front and center axles.

These brakes provide outstanding

stopping capability, while maintaining

maximum durability and low wear

characteristics.

Fastest Hoist Cycle Times. Carried over

from the E Series II, fast body raise and

lower times mean less time spent in the

dump area.

Load-Carrying Capacity. The 740 has a

large target area to provide consistently

high load-carrying capacity. Its

diverging flow design gives clean load

ejection, which maximizes production

and avoids the waste of material

carryback.
