durability. The front 240° of circle teeth
are hardened to reduce wear and ensure
component reliability.
Drawbar Construction. The A-frame
drawbar features a tubular design for
high strength and optimum durability.
Aggressive Blade Angle. With a long
wheelbase the operator can obtain
aggressive moldboard angles, so material
rolls more freely along the length of the
blade. This is particularly helpful when
handling very dry materials or cohesive
soils. Better material control gets the job
done faster, requires less power and
saves fuel.

power and efficiency while reducing the environmental impact.
Power Management. The 140M Power
Management System automatically
delivers an additional five horsepower
in each forward gear 1st through 4th,
and each reverse gear 1st through 3rd.
This standard feature optimizes rimpull
for all gears by balancing traction, speed
and horsepower while conserving fuel.
The system limits horsepower in lower
gears, which helps reduce wheel slip
where traction is limited. With the
Variable Horsepower Plus (VHP Plus),
which is optional on the 140M and
standard on the 140M AWD, an
additional five-horsepower is delivered
in each forward gear 5th through 8th
for more power at higher speeds.
ACERT™ Technology.
ACERT Technology allows Cat
engines to supply more power per unit of
displacement without causing premature
wear. This breakthrough technology
reduces emissions during the combustion
process by using advanced technology
in the air and fuel systems, in
conjunction with integrated electronics.
ACERT Technology enhances overall
engine performance while dramatically
reducing exhaust emissions.
Fuel Delivery. Both the C7 and C9
engines with ACERT Technology
use multiple injection fuel delivery to
precisely shape the combustion cycle.
Several small ignitions lower combustion
chamber temperatures, generate fewer
emissions and optimize fuel combustion.
Bottom line: more work output for your
fuel cost.
Performance. The Cat C7 and C9 engines
meet specific performance requirements
for 140M and 140M AWD applications.
Both engines provide superior torque
and lugging capability that can pull
through sudden, short-term increases in
loads, maintaining consistent, desirable
grading speeds to get the work done
faster without downshifting.
Hydraulic Demand Fan. The hydraulic
demand fan automatically adjusts cooling
fan speed according to engine cooling
requirements. This system reduces
demands on the engine, putting
more horsepower to the ground
and improving fuel efficiency.
Exhaust Emissions Certified. The Cat C7
and C9 engines with ACERT Technology
meet or exceed all U.S. EPA Tier 3 and
European Union Stage IIIa emissions
control standards.

Page 13
Hydraulics
The 140M electro-hydraulics enable advanced machine controls with precise and
predictable movements.
Consistent and Predictable Movement.
PPPC valves have different flow rates
for the head (red) and rod ends (blue)
of the cylinder. This ensures consistent
extension and retraction speeds for
each cylinder, and gives the operator
a consistent and predictable response
every time an implement control
is moved.
Balanced Flow. Hydraulic flow is
proportioned to ensure all implements
operate simultaneously with little effect
on the engine or implement speeds.
If demand exceeds pump capacity, all
cylinder velocities are reduced by the
same ratio. The result is improved
productivity in all applications.
Advanced Electro-Hydraulic System.
The 140M incorporates a state-of-the-art
electro-hydraulic system. This technology
is the foundation for revolutionary
changes of the machine and implement
controls. Advanced joystick controls

movements and the reliability
you expect from Caterpillar.
Blade Float. Blade float is built into the
blade lift control valves and is optional
for some auxiliary hydraulic functions.
The blade float feature allows the blade
to move freely under its own weight.
By floating both cylinders, the blade
can follow the contours of the road
when removing snow. Floating only
one cylinder permits the toe of the
blade to follow a hard surface while
the operator controls the slope
with the other lift cylinder.
Cat®XT™ Hose. Caterpillar hose
technology allows high pressures for
maximum power and reduced downtime.
Intelligent routing minimizes exposure
to damage. Hose clips prevent hose
rubbing and excessive vibration for
lower owning and operating costs.
Independent Oil Supply. Large, separate
hydraulic oil supply prevents crosscontamination and provides proper oil
cooling, which reduces heat build-up
and extends component life.
Load Sensing Hydraulics (PPPC).
The time proven load-sensing system
and the advanced Proportional Priority
Pressure-Compensating (PPPC, or
“triple-PC”) electro-hydraulic valves
on the 140M are designed to provide
superior implement control and enhanced
machine performance in all applications.
Continuous matching of hydraulic flow
and pressure to power demands creates
less heat and reduces power consumption.
