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.
