Sounds like you need a skidsteer. Tractors are great for mowing and working up the dirt but if you want to move much dirt then get a skid steer.
With 5 acres to bush hog quarterly I definitely need a tractor.
I'd love a skid steer like a bobcat, but in my particular situation that'd be more of a rental.
Or if I was rich, but then I'd buy a bulldozer & take it to Granby Colorado for upgrades.
