Here is a good suggestion, the 52" LazerHP w/ a 23hp Kohler<<< The reason for the ridder vrs the W/B is: 1: the seat 2: the option of adding a leaf vac 3: option of pulling an aerater 4: able to mount a spreader on it 5: might be able to squease 1 or 2 more in a day 6: wont be as tired at the end of the day from standing Lets put it this way, I mow a great deal of 1/2 acres lawns with a 60" and can see a big increase in it over a 52" hydro wb. But most of my accounts are well over that size. A hydro 52" WB with a "Velke" would work fine to, but have to stand. I think from what I have read you are on the right track. Good luck.
