I mainly have residential accounts that are about 5k-10k in size. I have some bids out for larger commercial properties. I use my 52" walk-behind and never had a problem with the deck being to big. The engine is a 19hp exmark hydro. My question is will I regret getting a 60" exmark 23 hp? I worry that the strip will look to "big" on some of my smaller residential lawns, or scalping may actually become an issue? Also, if I get these bigger commercial properties an employee will be doing most of the mowing so is a less experienced operator going to struggle more with a 60" walk behind compared to the 52"? I would still have the 52" and run the 60" along with it.
