I am starting my new business in 04 and I am in the market for a mower. I think I am going to purchase a 60" Lazer Z by exmark. Does anyone think that this is too much mower for a new business. I plan on having 30 to 40 accounts by the end of the season. Also, I was wondering how important it is to carry a large walk-behind mower. Could I get by with a small push mower.
