Sometimes the job is just too big and too nasty for anything but a full-sized utility vehicle. And when that's the case, the Kawasaki Mule™ 4000 is ready to go. As the foundation of Kawasaki's full-sized utility line, the Mule 4000 offers all the hardware and technology you need to tackle really big jobs, including a full-sized chassis, powerful four-stroke V-twin engine with digital fuel injection and serious towing capacity, a fully automatic transmission, locking rear differential and a tilting cargo bed. Think of the Mule 4000 as the stronger big brother to an already capable Mule 600 series machine.
