JCB 4CX: backhoe loader with four-wheel steering
The JCB 4CX is a larger and more powerful backhoe loader than the 3CX, produced since 1980. We look at the versions, engines, transmission, and what to check when buying a used 4CX.
4CX in brief
The JCB 4CX is a heavier and more powerful machine than the 3CX with a front loader and rear excavator. It often features four-wheel drive and four-wheel steering, making it highly manoeuvrable with excellent traction.
The operating weight is typically around 8.5–9 t, with a digging depth of about 5.5–6 m. It's used in roadwork, utilities, earthmoving, and municipal tasks.
Versions and series
Available versions include Sitemaster, Contractor, and Super. They differ in specification, cabin comfort, and additional equipment. Newer versions offer better visibility and ergonomics.
Some machines have a sliding side excavator, while others have a fixed one. Hydraulics also vary: some have additional lines for hammers or other attachments.
Engines and transmission
Earlier 4CX versions often have Perkins engines, while newer ones feature JCB's own Dieselmax or EcoMax diesel engines. Some meet stricter emission standards.
The transmission is either mechanical reverse or Powershift. Four-wheel steering is crucial: check that all modes (four-wheel, crab, two-wheel) operate smoothly.
What to check when buying a used 4CX
Check the engine hours, leaks, starting, and smoke. Test the transmission and four-wheel steering — movements should be smooth, without juddering or strange noises.
Check the condition of the cutting equipment and loader bucket teeth and wear, cylinder leaks, and stabilizer condition. Inspect the frame for cracks, the condition of the axles and brakes, and whether the machine has been heavily used with a ripper.

Frequently asked questions
How does the 4CX differ from the 3CX?
The 4CX is larger and heavier, with a longer wheelbase, greater ground clearance, and often features four-wheel drive. The 3CX is simpler and more affordable.
What is four-wheel drive?
It's a system that allows all four wheels to turn, enabling the car to corner with a tighter radius. In some modes, you can drive 'crab-style'—diagonally.
Is it worth buying a 4CX with Powershift?
Yes, if the transmission operates smoothly. Powershift is more convenient for towing, but repairs can be pricier than a manual reverse gear.
