Advanced technology improves hydraulic efficiency
Power to do more faster
When lowering the boom, this system uses the downward force generated by the boom’s weight to push fluid to the shovel arm. This greatly reduces the need to apply power from outside the system.
When you need more power instantly, engage Power Boost to get 10% more power.
