I was going to buy a Bad Boy with a 60" deck and the Briggs engine. The shop owner's daughter cornered me, she graduated with my youngest daughter, and told me to get the 54" deck and the Kawasaki engine for about the same money. Said the 60" deck sticks out too far from the wheels and tends to scalp the yard. And, so she said, the Kawasaki will run longer, quieter, and burn much less gas. So when a pretty young blond tells me what to buy, I buy it.
I've had to replace one belt, large stick hung in it, sounded like a helicopter until I shut it off. And replaced the starter solenoid. Last two years I've mowed around four acres weekly. This year I'm back to an acre.
I did own a Gravely. It had the Kohler Command engine. I was told it was a 500 hour engine. Sure enough, threw a rod at 502 hours. And, as the young lady said, the 24-hp Kawasaki engine is smooth and burns less gas than the 17-hp Kohler it replaced.
Oh year, the Bad Boy has an electric height adjust, my wife loves that.
