The True zero tailswing JCB 55Z-1 mini digger is incredibly manoeuvrable even in the most confined spaces because there’s no rear overhang outside the footprint of the tracks.

The efficient 2.2-litre Perkins 404D-22 engine delivering 35.7kW at 2000rpm powers the 48Z providing the optimum fuel efficiency. Tonne for tonne of material moved, the 48Z is a leader in its class when it comes to fuel efficiency. Tracking performance is smooth and precise, ensuring high dozer capabilities and fast travel times. To increase productivity, our auto kickdown motors automatically adapt to changes in terrain, increasing productivity and reducing operator fatigue.

Your JCB 55Z-1 compact excavator generates huge bucket tearout forces of 38kN and dipper forces of up to 22kN. What’s more, by perfectly matching our boom and dipper, JCB have created optimal dig end geometry, helping you to work and load in confined areas with ease. Bucket rotation is a huge 181˚, offering great spoil retention during truck loading. Smooth, precise and balanced multi-functioning is easy with this excavator, courtesy of a premium closed centre hydraulic system that provides improved flow sharing.



The new JCB 55Z-1 mini digger cab is fully ROPS and TOPS compliant. For even more protection to both cab and operator. JCB’s Safety Lever Lock fully isolates this mini digger’s hydraulic functions to prevent unintended movement.

Our unique 2GO system ensures your mini excavator hydraulics can only be operated in a safe lockable position via two separate inputs. An overload screen displays a bar chart from green to red, indicating whether the overload point is close or exceeded. Once the limit is passed, the buzzer sounds and the bar flashes to warn the operator. A large track frame width and low centre of gravity helps the JCB 55Z-1 compact excavator to offer amazing stability.

This powerful JCB small digger offers greater visibility than our outgoing JCB 8045, ensuring easier, safer trench digging and manoeuvring. This is thanks in part to a 70/30 front screen split. While the upper screen swings into an overhead storage position, the lower screen can be removed and stowed inside the cab.
