Hi Becca, I've got near to about the same amount of grass to cut that you do. I have about 3 acres here at my place, and an 1 1/2 at my parents. I found a used TC21d with FEL, and 60" MMM for $13,500. Its perfect for me. The other tractors you mentioned are also good choices. The BX would be a little nicer if you have a lot of tight areas. You've got some great advice here from all who posted. I wish you good luck whatever you decide. Kent
