An Industrial Strength 4x4 Side x Side to Get the Job Done! Whether working hard on the construction site or tackling the trail, the reliable 2014 Mule™ 4010 4x4 is the side x side that makes work seem like play. Loaded with awesome features and four wheels to replace the hooves of old, it will help workers get their jobs done no matter the task. Besides the convenience of selectable four-wheel drive, this modern machine mounts a fully automatic transmission and reliable 617 cc V-twin engine onto a heavy-duty chassis. Yesterday's pioneers would wish their pack animals were as easy to maneuver as this tough Mule, thanks to its electric power steering (EPS) and Digital Fuel Injection (DFI®).
