Have you considered a compact tractor, like a JD 1025R? They are amazingly versatile and can be had with a 60" drive-over mower deck. Plus you can get all sorts of other attachments that are incredibly handy around an acreage. Loader, pallet forks, box blade...even a backhoe. There are many choices out there. JD would be at the top of the price spectrum. Some of the imports are very capable and considerably less, though likely not as refined as the Deere.
