i am looking for a new mower for my business. I have picked up several large accounts that have some hills. I currently use a 52" surfer and a 2000 snapper hydro with a 61" deck. I need something faster like the surfer. I was looking at either getting the snapper fastback, another surfer or the lazer z from exmark. I need something that is fast and good on hills. I was leaning more towards the fastback but I wanted to see if anybody had first hand experience. Let me know your thoughts. Thanks.
