The operator of a JS140 tracked excavator is notified immediately of an air filter blockage, low coolant level or high hydraulic oil temperature via audio and visual warnings on the instrument panel.

A belly guard on the lower frame and underside protection for the upper frame is designed to protect the JS140 hydraulic excavator from on-site damage.

There’s anti-slip plating on the upper decks of this JCB excavator, keeping operators safe when they’re servicing or inspecting.

ROPS and FOPS cab guarding protection is available on the JS140 tracked excavator.


JCB’s Plexus Oil Filter system constantly filters the hydraulic fluid, reducing the risk of contamination. This means that hydraulic oil life on the JS140 tracked excavator is a massive 5000 hours, while the hydraulic filter lasts 1000 hours.

To increase the engine life of this 360 excavator, an air pre-cleaner system is fitted as standard.

By using graphite impregnated bronze bushes, boom and dipper greasing intervals on this tracked excavator are 1000 hours for normal applications.

To keep downtime to a minimum, the JS140 tracked excavator’s high capacity fuel pre-filter also acts as a water separator, catching dust and impurities and helping to avoid blockages in the main fuel filters.

Basic checks couldn’t be simpler. The low-profile bonnet opens and closes easily, courtesy of gas struts, while routine inspection points are quickly accessible. The engine radiator and hydraulic cooler are mounted side by side for efficient servicing and cleaning.

The JS140 tracked excavator’s electrics benefit from IP67 dust and waterproof connectors for long-term reliability.
