I looked at them today & know that I want the suspension. That means lightning or better. They sure have alot of engine choices. He had a 31 hp kaw 60" lightning for 8000.00 bucks. Thats not any different than the exmark I looked at. I will use the mower for around 8 to 10 acres a week, or whenever the grass needs mowed. Is that a good price? Any dealers around that know? I would like opinions of any kind as to what motor & why 31 kaw, 35 briggs. I only wanted to spend 7 grand, but I need the suspension. Thanks for your help.
