Capability and value in a full-size utility machine.

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.

 Automatic fast idle speed control eliminates the need for a choke, allowing the operator to drive off immediately after a cold engine start  
 Throttle bodies feature sub-throttle valves for optimum performance and drivability. The sub-throttles are located behind the main throttle valves and controlled by the ECU for smooth throttle response.  
 Automatic digital ignition system helps ensure smooth, efficient operation  
 Maximum engine speed is controlled by the ECU, eliminating the need for a mechanical governor  
 Offers easy engine operation and reduced maintenance requirements  
Cab Frame Air Intake
 Draws engine air and converter cooling air from the top of the cab frame where there is less dust, so the air filter stays cleaner longer  
Environmentally Friendly Emissions
 DFI® precision reduces fuel consumption and cuts exhaust emissions  
 Positive crankcase pressure ventilation system sends blow-by gases back through the intake tract to be burned by the engine
