The Bravo 21 BBC is a 21“ commercial lawnmower powered by a Kawasaki FJ engine and has a 2-speed heavy duty transmission that is fastest in its class.
Model 21-610 (Kawasaki FJ180V Engine) is equipped with a Zone Start safety package. When the Zone Start device stops the blade from spinning the engine is also shut off. The Zone Start mower is a bit simpler in complexity; therefore the price on this model is a bit lower.
