New Cat 559 knuckleboom log loaders give both high production and low fuel consumption. Different power modes and an automatic idle down system work together to maximize production, while minimizing fuel use. For normal loading operations, the Run Mode saves more than 20% in fuel. The Power Boost Mode provides 40% more productivity muscle for heavy duty delimbing, slashing and loading applications.
Activated by a flip of the switch, the Run and Power Boost Modes allow the operator to match engine speed and pump flow to the application, yielding maximum production and minimum fuel use. Idling the engine decreases fuel consumption. As soon as the operator moves a joystick control or swing pedal, the engine automatically returns to the previous throttle setting.
