One Engine Instead of Two

The carrier-mounted XL 4100-II is a far different excavator than the model it replaces, the XL 4100. The new machine embodies Gradall's hallmark design features—a tilting telescopic boom and a highway-worthy chassis. It also keeps the high-pressure hydraulic system. Beyond these basic elements, though, nearly every other design aspect is new for the XL 4100-II. Changes range from big-ticket items—the carrier frame, boom, boom cradle, cabs, hydraulic design and engine layout—to detail items, such as dent-resistant fenders, LED swing lights and "plug-in" convenience for adding work lights, cab sound systems and air conditioning. With the single-engine design, Gradall says the machine has increased performance and saves money on filters and downtime associated with routine maintenance. Estimated list price: $275,420.
