The most powerful models in the QS range are powered by JCB’s six-cylinder Dieselmaxx engine, delivering significant fuel saving and as much as 8% less fuel than competitive generators.

At the heart of this range is JCB’s 6 cylinder DieselMaxx. Based on the company’s successful 4.8-litre engine, you can expect the same great productivity and efficiency from a tried and tested engine. The DieselMaxx engines have 500-hour service intervals, low fuel economy and low noise levels, helping to deliver low operating costs and maximum uptime for customers, making these a great engine for our reliable generators.
