COST OF OWNERSHIP AND EFFICIENCY.

THE LATEST 3CX AND 4CX BACKHOES DON’T JUST PROVIDE YOU WITH THE POWER TO GET THINGS DONE; THEY ALSO OFFER YOU COUNTLESS FEATURES TO ENSURE THAT PERFORMANCE IS EFFICIENT, AND OWNERSHIP COSTS ARE REDUCED.

An efﬁcient drivetrain.

JCB’s EcoMAX engine doesn’t require exhaust

after treatment, heat-resistant oils or AdBlue, all of

which saves money on servicing.

By producing high levels of power and torque

even at engine speeds as low as 1200rpm, EcoMAX

can provide fuel-efﬁcient matching of transmission

and hydraulics.

JCB’s unique TorqueLock system is now standard on

81kW (109hp) Powershift model 3CX and 4CX

backhoes. Combined with our optional 6-speed

Autoshift transmission, it can help save up to 25%

on fuel and 10% on road travel time.

For ultimate efﬁciency, our unique new

entry-level 55kW high torque (400Nm) engine

provides excellent excavator performance with the

fuel usage of a low power unit.

3CX/4CX ECO BACKHOE LOADER2

Residual beneﬁts.

Our EcoMAX engine can be adapted to run on

lower-grade fuels, which makes the 3CX and 4CX

easily resalable across different territories. This, of

course, boosts residuals.

A JCB 3CX or 4CX is a great asset in many respects,

not least ﬁnancially – huge global demand, plus

legendary productivity, plus superb build quality

equals maximum resale value.

Added efﬁciency.

As products of the JCB Efﬁcient Design programme,

our T4i backhoe loaders use up to 9% less fuel than

our Tier 3 models.

COST OF OWNERSHIP AND EFFICIENCY

To reduce noise and save fuel, we’ve ﬁtted the 3CX

and 4CX with a viscous fan as standard; this only cuts

in when it’s needed, and doesn’t draw engine power.

High back-off brakes reduce viscous drag during

roading and rehandling, which in turn improves

economy by up to 2%.

Because the 3CX and 4CX are ﬁtted with a

Thatcham-approved security system (depending

on territory), you could beneﬁt from lower

insurance premiums.

A new high output variable ﬂow pump reduces cycle

times and saves fuel. On manual machines, it also

provides lighter lever effort for easier control.

QUALITY, RELIABILITY AND DURABILITY.

THE LATEST JCB 3CX AND 4CX ECO MACHINES ARE DESIGNED FOR HARD WORK. THEY’RE MADE USING ONLY THE VERY FINEST MATERIALS AND PROCESSES, WHICH ARE TESTED, TRIED AND PROVEN TO EXCEL. THEY’RE ALSO PROTECTED FROM THE INEVITABLE RIGOURS OF SITE LIFE.

Damage limitation.

To stop the 3CX or 4CX’s kingpost hoses from

snagging and sustaining damage, we enclose them

in a ﬂexible, robust guide.

The steering ram on these backhoes is protected

from impact damage whilst loading, because it’s

mounted behind the front axle.

4 3CX/4CX ECO BACKHOE LOADER

To protect boom and dipper hoses from the

perils of trenchwork, we’ve enclosed them inside the

rear structures of the machine.

The rams on our 3CX and 4CX machines are

ultra-reliable because they’re protected from

debris when loading by optional JCB clam shovel

ram guards.

To safeguard from impact damage on site, the

3CX and 4CX are now ﬁtted with rear light guards.

Built to last.

For added rigidity – and to protect hoses from

damage – a 3CX or 4CX has ﬂat plate-depressed

loader arms, while cat tail welds reduce stress

concentrations.

The plastic fuel tank on the 3CX and 4CX is

completely rustproof for ultimate fuel injection

system protection.

The single-piece composite cab ﬂoor on these

backhoes is also rustproof, and has moulded water

channels.

JCB’s robot welded single-piece chassis maximises

strength and minimises weight.

Tested to the limits.

QUALITY, RELIABILITY, DURABILITY

All the materials with which we construct our

backhoe loaders are tested to the very max. By

exposing those materials to extreme temperatures,

chemicals, salt, oil and light, we know they’ll survive

the most hostile conditions.

To prove the durability of our new EcoMAX

engines, we’ve tested them for 110,000 hours in 70

different machines across the toughest applications

and environments.

The axles and transmissions of JCB 3CXs and 4CXs

are built for a 12,000-hour life, with the heavyweight

axles designed to withstand massive shock loads. The

rear axle alone has a static load rating of 25,000kg,

and a dynamic load rating of 12,500kg.

PRODUCTIVITY AND PERFORMANCE.

JCB BACKHOES HAVE ALWAYS LED THE WAY IN POWER AND PERFORMANCE, AND OUR LATEST 3CX AND 4CX MODELS ARE NO EXCEPTION. IN EVERY RESPECT

For enhanced loading performance and smoother gear changes, we offer a 6-speed gearbox with low ratio ﬁrst and second gears.

– FROM DIGGING TO LIFTING AND MANOEUVRING – THESE MACHINES WILL MAXIMISE YOUR PRODUCTIVITY.

A productive drivetrain.

Choose from three engines to suit your

requirements – with 55kW, 68kW and 81kW

options, you can balance ultra efﬁciency against

ultimate performance.

To give your 3CX or 4CX even greater traction

and performance, as well as reduced tyre wear, opt

for our automatic limited slip differentials.

Innovative hydraulics.

There’s more tractive effort at the pile than ever,

thanks to new variable ﬂow pump power management

combined with our new EcoMAX engine.

Fast and responsive cycles are guaranteed, courtesy of an increased 165 l/min peak hydraulic ﬂow.

With a 160-litre fuel tank, the 3CX and 4CX ECO machines are designed to do a huge amount of work between reﬁlls.

The 3CX Contractor and 4CX’s heavy-duty lift

rams provide 3.87 tonnes of force for improved

lifting performance.

Digging further.

A 3CX or 4CX ECO’s 4-ram self-levelling loader

automatically adjusts the shovel on both raise and

lower cycles without any need for manual

adjustment. It also provides unhindered front shovel

visibility, especially when loading at height.

The JCB return-to-dig feature means operators can

quickly reset the shovel to dig.

To ensure an extra 1.2m dig depth and reach

– and to minimise repositioning – the 3CX and 4CX

are ﬁtted with our inner box design Extradig feature.

Both the 3CX and 4CX ECO boast high ground

clearances of up to 370mm, together with 20°

departure angles. This means operators can work

easily on steep slopes and uneven ground at

maximum productivity.

JCB 4CX: the ultimate backhoe loader.

PRODUCTIVITY AND PERFORMANCE

As the largest, most productive backhoe

model we produce, boasting unparalleled power,

peformance and versatility, the JCB 4CX ECO is

the ideal machine for just about any application,

COMFORT AND EASE OF USE.

IN ORDER TO HELP YOU REAP THE MAXIMUM BENEFIT OF THE 3CX AND 4CX’S SUPERIOR PERFORMANCE, WE’VE DESIGNED THESE MACHINES TO BE ALL-DAY COMFY, ERGONOMIC AND EXTREMELY INTUITIVE FOR OPERATORS TO USE.

A great place to work.

All our ECO backhoes have low noise levels, with

our 55kW (74hp) engine models offering the

quietest operation.

To help operators get to work quickly and safely,

our optional heated front screen removes any

built-up frost and ice without the need to climb

across the machine on cold mornings. A cab

pre-heating option can be set to warm the cab

automatically without starting the engine.

There’s storage aplenty in our 3CX and 4CX

cabs; work tools are easy to carry, the cab

environment is well-organised and, on A/C models,

there’s an in-cab cool box for food and drinks.

JCB’s single piece glass provides optimum visibility across the work area of a 3CX or 4CX ECO, while our narrow front bonnet allows extra visibility to the front shovel and wheels.

For added comfort and reduced material spillage,

JCB’s SmoothRide System minimises bounce

during travel.

Exclusive to JCB backhoe loader,

integrated a hot drinks machine option into the cab to

provide you with a delicious cup of hot tea or coffee

throughout the day.
