I'm no pro like most of you but I would like a commercial grade mower. Can anyone tell me the pros and more importantly the cons of Bad Boy mowers. I'm also looking at the Gravely 152M XDZ. The Gravely dealer talked trash on the Bad Boy pumps, hydrogear 10A, verses the Gravely Hydrogear 12cc/ hydrogear 15E motor. This all sounds like Greek to me.
