Load-Sensing Hydraulic System.
The variable displacement piston pump
and flow-sharing hydraulic valves
sense work demand and adjust flow
and pressure for increased productivity.
Load-sensing hydraulics deliver:
• Maximum lift and dig forces at any
engine RPM
• Cooler hydraulic system
• Better fuel efficiency
• Quieter operation
• Reduced wear on components
Hydraulic Pump. The variable
displacement piston pump improves
implement response and speed while
still providing high forces at any engine
speed. A supplemental gear pump
provides increased flow and
responsiveness.
Torque Limiter Control. The pump
torque limiter control manages
distribution of engine power to the
hydraulic system and drive train.
E-Series improvements produce more
aggressive backhoe digging and
stronger truck loading performance.
Flow-Sharing Hydraulic Valves.
Technology leveraged from Cat
Hydraulic Excavators, new flowsharing hydraulic valves automatically
distribute flow to optimize multifunction implement performance.
Closed-center implement valves signal
hydraulic system requirements to a
control valve located on the pump.
Clamps and Bushings. Metal clamps
with rubber bushings are used at hose
attachment points to eliminate metal-tometal contact and increase wear life.
Cat XT-3 ES ToughGuard™ Hoses.
Improved bend radius and abrasion
resistance provide reliable long life
in the toughest conditions. Made of
four overlapping, insulated wire spiral
wraps bonded together for durability,
Cat XT-3 ES (Enhanced Spiral)
ToughGuard hoses exceed SAE
certification standards. The hose routing
protects them from work damage, and
hose failure is substantially reduced.
Cat XT-3 ES ToughGuard hoses
combined with Cat couplings and O-ring
face seal fittings provide a leak-free
system. All backhoe hydraulic circuits
utilize the new ToughGuard hose with
extended wear characteristics.

Cat C4.4 Diesel Engine. The Cat C4.4
engine meets all U.S. EPA Tier 3/
EU Stage III emissions requirements.
It delivers high horsepower, increased
torque rise and reliable power with low
emissions. It provides excellent fuel
economy and system durability.
Direct Injection Fuel System. Individual
unit fuel injectors deliver efficient and
accurate fuel metering and reduced
emissions. The water separator service
indicator ensures the operator is alerted
when service is necessary.
Enhanced Roading Speed. Maximum
roading speed has been increased to
40 km/h (25 mph) for faster travel
between jobsites.
Air Cleaner. A dry-type axial seal air
cleaner with automatic, integrated dust
ejection system provides more efficient
pre-separation. The two-stage air filter
incorporates both air cleaner and
precleaner functions into a single
unit mounted under the hood.
New Axles. New heavy-duty axles are
designed specifically for demanding
backhoe loader applications. Features
include outboard planetary gear sets and
brakes for serviceability and longer life.
Auto-Shift Transmission. The standard
automatic transmission matches gears
with grade and load conditions. Top gear
is selected with the twist grip control on
the steering column. At the touch of a
switch, manual mode gives the operator
control over gear selection, as a power
shift transmission.
Transmission Kick-Down Switch/
Neutralizer. Located on the loader
control, the kick-down switch allows
the operator to downshift through the
gears. When this switch is depressed
for more than one second, it serves as
the transmission neutralizer to maintain
engine and hydraulic speed when
truck loading.
Standard Four Wheel Drive (4WD).
Heavy-duty front drive axle can be
engaged at any time by activating the
switch on the front console. The switch
can be activated while the machine is
stopped or moving, with or without
load. 4WD features outboard planetary
gear final drives and improves mobility
and loader performance in poor traction
conditions.
Brake Mode Selector. The brake
mode selector switch has three positions:
two wheel drive, two wheel drive with
all wheel braking and all wheel drive.
Center position provides two wheel
drive for better tire life while roading
and engages the front axle when brakes
are applied for improved braking
performance.

Ride Control System. The Ride
Control System incorporates a nitrogen
accumulator in the loader lift circuit
that smooths the ride in all conditions,
including load and carry, highway
roading, or simply moving around
the job site.
Improved Productivity. Ride Control
improves material retention in the loader
bucket for increased productivity and a
cleaner jobsite.
Controllability. Ride Control reduces
machine loping, providing a smooth and
stable ride for increased operator comfort
and reduced operator fatigue.
Convenient Operation. 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 finishing applications.

High Rotation Backhoe Linkage.
Single pin bucket linkage contributes
to best-in-class rotation of 198 degrees
for all applications, eliminating the need
to change pin position whether loading
trucks or digging tight, vertical wall
trenching. An extra pin hole in the
E-Series buckets is provided to maintain
compatibility with previous machine
models.
Backhoe Boom. The excavator-style
boom features box section fabrication
with thicker plates 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.
Backhoe Swing Casting. New swing
casting is designed to handle the high
performance of the E-Series backhoe.
It features replaceable bushings for
durability and serviceability.
Thumb Mounting. Thumb mounting
provisions are standard on every
Cat Backhoe Loader for added machine
versatility. Hydraulic thumbs are
available factory-installed.
Single Tilt Loader Linkage. The standard
single tilt loader linkage features strong
lift and breakout forces for solid
performance in backfilling and truck
loading applications. The machine is
equipped with either a general purpose
or multi-purpose pin-on bucket to meet
your specific needs.
Loader 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.
