Besides the mowing requirement, you might want to think what implements you will want to operate. For example, box blade for road work, Grapple for brush work, plow or tiller for garden, or pallet forks etc. That may help you decide what size you want to use over the next 30 years. If you look at compacts, might look at Kubota L series. I have about 4 acres and do some clearing and road maintenance (gravel road) and have the L4701. Never regreted having the larger tractor - stronger hydraulics, higher FEL lift and better overall traction. Best Wishes, Larry
