Tough enough to perform any job you ask of it

The JCB JS370 sits at the top of our range of heavy tracked excavators. Weighing in at around 37 tonnes, it’s engineered with exceptional strength, productivity, efficiency, comfort, safety and ease of maintenance.


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


Meanwhile, this tracked excavator’s engine is a highly efficient Isuzu 210 kW unit, compliant with Stage 3b and Tier 4i. The benefits of the JS370 series of tracked excavators don’t end there either.

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 JS370, strength and durability come as standard.


We use Finite Element Analysis with extensive rig and endurance testing to make these excavators last longer. A JCB JS370’s reinforced boom and dipper is made of high tensile strength steel, with single piece wrapper plates and internal baffle plates for long life durability.


The high-strength undercarriage of JS370 tracked excavators 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 JS370 tracked excavators is then welded to both the upper and lower undercarriage frames, and stiff, durable doors provide further strength.

It’s more important than ever to save money and time so it’s just as well that JCB JS370 tracked excavators are designed to make the most of both.


Our Tier 4 Interim compliant Isuzu engine has a high power rating – 210 kW – that’s 25% more than our outgoing model. Yet, because it produces high torque (27% more than the outgoing model) at low revs, it’s very efficient too.


A massive 155kn bucket tearout makes our JS370 tracked excavators up to 12% more productive than the closest competitors, and the JCB JS range quickhitch 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 excavators to tailor performance to any application. Auto, Economy, Precision and Lifting modes provide very different optimised settings.

We’ve designed JCB JS370 tracked excavators 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 excavators. Grease points are centralised on JCB 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 JS370 tracked excavator’s engine radiator, hydraulic cooler and intercooler can be serviced individually and cleaned easily.
