Our EcoMAX Stage IV/T4F engine uses up to 10% less fuel than our Tier 3 units, saving you money. This is partly because EcoMAX produces high torque at just 1,500-1,600 rpm, and also because JCB uses efficient advanced hydraulic technology. JCB’s tracked excavators use hydraulic regeneration to recycle oil across the cylinders for faster cycle times and reduced fuel consumption. Auto-idle technology automatically reduces the engine speed of the JS220 tracked excavator when its hydraulics aren't in use. Simultaneous tracking and excavating is smooth and fast with intuitive multifunction operation, and four operating work modes allow operators of these 360 excavators to tailor performance to any application. Auto, Economy, Precision and Lifting modes provide very different optimised settings. For ultra-versatility, JCB offers a full list of auxiliary pipework options including hammer, auxiliary, merged and low flow.
