Well first of all that is not the best residential mower available in that price range...but secondly and even more importantly is the fact that something like that is not rated to cut three acres as you are hoping to do. They just are not designed to cut that much land and hold up over a period of time.
I would look at the Cub Cadet Z-Force machines. They are actually rated to cut that much land and will hold up. Cub is also offering a Z-Force with a fabricated 48" deck this year that will retail for $4,599.00. Either way to get a zero turn mower that is rated to cut that much grass you are going to spend 3.5K.
Now if you wanted a ridding mower you could get away spending about 2K...
