JCB’s JS 300LC 30 tonne excavator is towards the top end of our range of heavy tracked excavators.

This 30 tonne excavator is engineered with exceptional strength, productivity, efficiency, comfort, safety and ease of maintenance.

A closed box section revolving frame increases strength and reduces stress, and also makes these tracked excavators highly resistant to impact damage. We’ve used strong parts and components throughout – premium industry standards, in fact.

In addition, this tracked excavator’s engine is a highly efficient JCB 672 6 cylinder 7.2L DieselMAX. The benefits of the JS300 series of tracked excavators don’t end there…

JCB have designed the 30 tonne excavator to be comfortable, safe, ergonomic, simple and intuitive to operate. Which is good for operators of 360 excavators but even better for you; after all, great ease of use equals great productivity.

Cushioned boom and dipperends prevent shock loadings, protect your machine and increase operator comfort, while 6 viscous rubber mounts minimise noise and vibration.

A 70/30 front screen split for a clear view of the front right track, plus a large laminated glass roof window provide this excavator with exceptional all-round visibility.

To keep everything under control, JCB 30 tonne excavators have a balanced slew and electronic/hydraulic controlled slew braking. Function switches are easy to reach and include the heater and climate control panels, while the side unit doubles as part of the immobiliser code selector.


It’s more important than ever to save money and time so it’s just as well that JCB 30 tonne excavators are designed to make the most of both.

A massive 145kn bucket tearout makes our 30 tonne excavator up to 12% more productive than the closest competitors, and the Geith quick hitch system makes attachment changing fast and easy.

Simultaneous tracking and excavating is smooth and fast with an intuitive multifunction operation, and four operating work modes allow operators of these 360 excavators to tailor performance to any application. Auto, Economy, Precision and Lifting modes provide very different optimised settings.


JCB have designed their 30 tonne excavator to be low maintenance and easily serviceable. Which makes them affordable, efficient and highly productive.

Bonnets open and close easily with gas-assisted cylinders, and the service bays are large and wide for good access. 1000-hour boom and dipper greasing intervals and a 5000-hour oil life provide maximum uptime on these 360 excavators. Grease points are centralised on JS300 tracked excavators too, for safe and easy access to high level pivots. Likewise filters (engine oil, hydraulic oil and fuel).

Because they’re mounted side by side, the JCB 30 tonne excavator engine radiator, hydraulic cooler and intercooler can be serviced individually and cleaned easily.


Before you buy tracked excavators, you need to know they’re going to be tough enough to perform any job you ask of it. Fortunately, with a JCB 30 tonne excavator, strength and durability come as standard.

We use Finite Element Analysis with extensive rig and endurance testing to make these 360 excavators last longer. A JCB 30 tonne excavator’s reinforced boom and dipper is made of high tensile strength steel, with single piecewrapper plates and internal baffle plates for long life durability.

The high-strength undercarriage of JCB 30 tonne excavator is of a fully-welded X-frame construction for long-term durability even in the most demanding applications, and the rigid upper frame provides maximum durability and support.

The turret on JCB 30 tonne excavator is then welded to both the upper and lower undercarriage frames, and stiff, durable doors provide further strength.
