My brother went from a t-house to 3 acres. I told him to check out this site and compare dealers. It took 2 months, but here is his email.
After my two months of research, I found that Exmark was pretty much the best.... just expensive. I looked at a Scagg Tiger Cub and a Ferris 1000, but ended up with the Exmark. Seems like they were trying move some remaining new equipment because of the rapidly approaching end of summer. I'm sure next year they will have a more powerful one, but for what we need any commercial mower would do fine. Picked it up for $6300. Retail on it was $7600. With a 23HP Kawasaki engine.... it flies!!!!
