ALL NEW for 2019, the kawasaki Mule SX 4x4 is now Fuel Injected! Same great features as before: Kawasaki Mule SX 4x4 is the farm/ranch/job site/homestead workhorse that helped build the Olmsted Lock & Dam project on the Ohio River. The Mule SX 4x4 offers a 400cc single cylinder engine, selectable 4wd, a dump bed, light weight and easy maneuvering, with bulletproof attitude and reliability that has made this little utility vehicle the best in its class for years running. It is our best-selling side-by-side, and you will soon see why. Stop by for a test ride, and let us show you why this ranch hand is the best in the business.
