I'm looking to get the Scag Freedom Z with the 61 inch deck. It comes with either the Kawasaki FS730 or the B&S Professional Cyclonic Engine. The Kawasaki is 24 hp while the B&S is 30 hp. Which one should I get for homeowner use, 3 hours per week? One dealer doesn't like B&S and won't stock them unless absolutely necessary and the other said that the Kawasaki wasn't strong enough in that mower and prefers the 30 hp B&S. He tested both. Thanks.
