A basic workhorse with the performance and safety features of higher priced machines. The 420BU is available in four different widths – 21, 24, 28, & 40 inches (53, 61, 71, and 102 cm, respectively). Each model comes standard with a 12-volt on board electric starter and clutch. A passive vacuum and EcoSense emissions monitoring system are optional at extra charge (active vacuum is standard on the 40″ model).

 

Powered by an 18-HP, 603 cc Kawasaki engine, the 420BU uses 34 percent less fuel and requires 40 percent fewer oil changes than other machines in its class.
