The JCB JS300 is towards the top end of our range of heavy tracked excavators. Weighing in at around 30 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 165 kW unit, compliant with Stage 3b and Tier 4i. The benefits of the JS300 series of tracked excavators don’t end there either.
