I was at the JD dealer today looking at the Z's, There is a big JD Show here in the Atl. area starting tomorrow. My question is regarding the JD's with the one hydro, is this an issue? or is this as reliable as dual hydros? They will be having good prices I'm sure, I was told for under 1 Ac. the 737 with a 54" deck is the way to go, it has a 23hp Kaw. Any JD owners replies would be appreciated, I understand they cut wet grass very well, so they must cut dry even better?
