With standard pilot-operated joystick controls, a more
comfortable operator station, extendible stick design
and increased performance, the 430E/430E IT lets you
get more done with less effort.
Operator Station
Comfort, visibility and style.
Experience a whole new level of comfort with the spacious E-Series operator
station. The ergonomic, automotive style enhances the operator environment.
A narrow front dash provides excellent visibility to the front bucket. Reduced
vibration keeps operator fatigue low. In-cab storage compartment and lockable
tool and battery box provides ample space for tools and belongings. The operator
station also features an easy-to-read gauge cluster and increased legroom.
Automatic Engine Speed Control
This new feature reduces engine speed when the backhoe is not in use to conserve
fuel and lower environmental noise.
Air Suspension Seat
The standard air suspension seat is adjustable for a greater operating range and
more comfortable ride. A switch allows the seat to be tailored to support differing
body weights. Adjustable seat height accommodates all operators. The deluxe
cab air suspension seat also has an adjustable back support, lumbar support, seat
cushion extension, seat cushion tilt and vertical and angle adjusting armrests.
Improved Air Conditioning
The improved air conditioning system features enhanced air distribution and
performance for a more comfortable work environment. A nearly 20% increase in
air ow combined with improved louver locations provide superior operator comfort.
Configurations
The 430E operator station is available in 5 options – ROPS Canopy, ROPS Canopy
Plus, Standard Cab, Deluxe Cab and Deluxe Cab with Air Conditioning. See Standard
and Optional Equipment for details.
Controls
Reduce fatigue.
Low effort, ergonomic excavatorstyle joystick controls provide smooth
modulation. Thumb rollers provide
convenient, ngertip control of
auxiliary functions, eliminating
pedals on the oor.
One-Touch Low Idle
Located on the right hand joystick,
this button reduces engine speed
to low idle. This new feature will
reduce fuel consumption and
improve communication with
ground crew.
Pattern Selector
The pattern selector switch, located
in the cab, allows the operator to
change from excavator to backhoe
control pattern simply by pressing
a button. This allows the operator
to use the pattern they are most
familiar with to get more done,
faster.

Hydraulics
Load-sensing system matches power to demand.
The 430E has a load-sensing, closed center hydraulic system,
which closely matches power and ow to the demand needed
by the implements. So whether you’re in full trenching mode,
or delicately digging around services, you are in control.
In applications such as production trenching, speed is
important and the system will match the ow needed to
get the job done quickly and efciently. The load-sensing
hydraulic system also delivers:
A cooler hydraulic system
•
Better fuel efciency
•
Quieter operation
•
Reduced wear on components
•
Cat XT-3 ES ToughGuard™ hoses combined with Cat
couplings and O-ring face seal ttings provide a leak-free
system. The 430E also features new ow-sharing hydraulic
valves, ensuring proportional ow of oil to all hydraulic
cylinders, providing greater control and improving multifunction performance.
Ride Control
Delivers even greater
operator comfort.
The optional Ride Control System smoothes the ride in
all conditions, including load and carry, highway roading,
or simply moving around the job site. It reduces machine
loping, providing a smooth and stable ride for increased
operator comfort and reduced operator fatigue. The Ride
Control option improves material retention in the loader
bucket for increased productivity and a cleaner job site.
The system is easily engaged by a switch on the front
console. The Ride Control switch has three positions, ON,
OFF and AUTOMATIC. In the automatic position, the
Ride Control engages automatically as the travel speed
increases. At low speed, the system disengages for loading,
grading or nishing applications.

Power Train
Built for performance, power, reliability and fuel efficiency.
Cat Engine
The 430E features the Cat® C4.4 DIT (Direct Injection
Turbocharged) engine with ACERT® technology and meets
all U.S EPA Tier 3/EU Stage IIIa emissions requirements.
The increased horsepower and torque rise deliver improved
loading and roading performance.
Electronic engine control provides precise fuel metering
•
for optimized power, response and fuel efciency.
The water separator service indicator ensures the
•
operator is alerted when service is necessary.
Dry-type axial seal air cleaner with automatic,
•
integrated dust ejection system for more efcient preseparation. Both air cleaner and precleaner functions are
incorporated into a single unit mounted under the hood.
Transmission
The Cat standard power shuttle transmission provides four
speeds forward and reverse. Hydraulically shifted clutches
allow on-the-go direction and travel speed shifts. The optional
auto-shift transmission matches gears with grade and load
conditions. Top gear is selected with the twist grip control
on the steering wheel.
Hydraulic proportional control valves smooth speed
•
and directional shifts.
Transmission Kick-Down Switch/Neutralizer allows
•
the operator to downshift through the gears to rst.
Standard Four Wheel Drive (4WD) improves mobility
•
and loader performance in poor underfoot and can
be activated on-the-go.
Maximum roading speed of 40 km/h (25 mph) for faster
•
travel between job sites.
Cat Rear Axles are designed specically for demanding
•
backhoe loader applications. Axles feature outboard
planetary gear sets for easy serviceability and brake
design improvements for longer service life.
Brake Mode Selector
The brake mode selector switch has three positions: two
wheel drive, two wheel drive with all wheel braking and four
wheel drive. Two wheel drive with all wheel braking provides
better tire life while roading and engages the front axle when
brakes are applied for improved braking performance.
5
Loader
Choice of loader linkage to meet your needs.
Caterpillar offers a choice of single tilt or integrated
toolcarrier (IT) loader linkage to suit your application
requirements. The IT loader controls provide single lever
proportional control and ne modulation of the hydraulic
work tools. A thumb roller operates auxiliary hydraulic
functions such as the multi purpose bucket on the IT
machines.
Single Tilt
The standard single tilt loader linkage
features strong lift and breakout forces
for solid performance in backlling
and truck loading applications.
Integrated Toolcarrier
The optional integrated toolcarrier
(IT) loader linkage provides higher
breakout forces, as well as parallel
lift, for efcient loading and material
handling. Integrated toolcarriers are
highly versatile and can use a wide
range of Cat Work Tools for a variety
of applications.
Return-to-Dig
The return-to-dig system reduces
loading cycle times by bringing the
loader bucket back to the dig position
with an easy pull of the lever. By the
time the loader bucket is at ground
level, the bucket is angled correctly
for the next load or cut.
6
Backhoe
Boom and stick designed for high performance and easy service.
The E-Series backhoe delivers industry-leading digging forces. Serrated edges on the stick provide
improved material clamping for clearing and demolition applications. The single pin bucket linkage
contributes to best-in-class rotation of 205 degrees for all applications.
E-Stick Design
The optional extendible stick (E-stick) increases reach and dig depth by approximately 1.2 meters
(4 feet). The new design delivers increased life and easy in-eld adjustment with common hand tools.
Curved Boom
The excavator-style boom is built for optimum performance and durability. The curved design provides
additional clearance over obstacles while digging a trench or truck loading. The narrow boom enhances
the viewing area to the bucket and trench throughout the entire operating range.
Thumbs
Thumb mounting provisions are standard on every Cat Backhoe Loader for added machine versatility.
Hydraulic thumbs are available factory-installed. Mechanical thumbs are available through your
Cat Dealer.
