Just got this used yesterday. It's a hydro. Tried to run it on my lawn today, but it isn't cutting much. Sharpened the blades, no spacers. My bermuda is pretty low already, just wondering if it isn't cutting much because it's already so low. Second season in the business...first commercial mower. Since I've seen a couple of threads about wives, my wife is very supportive, but she is wondering why this commercial mower, that wasn't cheap, is not cutting. She told me, "Looks like your Honda cuts better than that!" Any advice is welcome.
