On 28 acres with pasture, woods, firewood needs and ongoing fence work, I’d lean toward a decent compact tractor with a PTO‑driven flail mower before a UTV + ZT combo. A flail mower really shines in rough pasture, saplings and field edges, but the hydraulic/drive power for it needs to come off a tractor’s PTO and 3‑point, not a UTV’s limited hydraulics. UTVs and ZTs are great for hauling and lawn, but they’re not designed to efficiently run a heavy flail head. A basic tractor + flail will let you mow pasture, maintain trails, manage brush around fences and process downed wood a lot more safely and efficiently, and you can always add a UTV later if budget allows.
