tbird,
I have a simple 24 horses in my JD (MFWD) and a fairly hilly, very rocky 5 acres. I brush hog (4 foot), box blade (5 foot), finish mow (5 foot) without even the slightest bit of trouble. Is your current machine 2 or 4 WD? I would think that a Kubota 2410, 2710, 2910, JD 42XX or NH 24, 29, or 33 (Boomers) would be more power than you'll ever need. I guess most of us would choose to get a biger machine if possible but you could save a fair amount of money going smaller. This would leave you more left over for attachments /forums/images/graemlins/grin.gif
