JS370 Tracked Excavator

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

The JS370’s new DIESELMAX 672 engine provides up to 25% fuel savings over outgoing models, while a closed box-section revolving frame increases strength and reduces stress. We’ve also created a new high-strength boom and dipper for this tracked excavator, and we’ve used only the very best components, like Berco running gear, Kawasaki pumps and Kayaba main control valves.


Comfort and Ease of Use

We’ve designed JCB JS370 tracked excavators to be comfortable, ergonomic, simple and intuitive to operate. Which is good for operators of our excavators but even better for you; after all, great ease of use equals great productivity.

Function switches on this tracked excavator are easy to reach and include the heater and climate control panels, while the side unit doubles as part of the immobiliser code selector.
JCB JS370 tracked excavators have a spacious luggage tray behind the operator’s seat.

The JCB Advanced Monitoring System keeps tabs on functions and inputs during different working modes.

Demist/defrost keeps a JS370 tracked excavator’s front window clear at all times in any conditions.



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

To keep everything under control, JCB JS370 tracked excavators have a balanced slew and electronic/hydraulic controlled slew braking.

A large floor area with large high grip pedals gives safe, easy and precise tracking.

A 70/30 front screen split provides a clear view of the front right track, while a large laminated glass roof window gives this 360 excavator exceptional all-round visibility.



We’ve designed JCB JS370 tracked excavators to be low maintenance and easily serviceable, making them affordable, efficient and highly productive to run.

Bonnets open and close easily with gas-assisted cylinders, and the JS370 tracked excavator’s 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 JS370 tracked excavators 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.



We use Finite Element Analysis with extensive rig and endurance testing to make our 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 welded to both the upper and lower undercarriage frames, and stiff, durable doors provide further strength.

For ultimate reliability, we construct our tracked excavators using only the very best componentry, including Berco running gear, Kawasaki pumps and Kayaba main control valves.
