Kestrel Take
The heavy-duty diesel work UTV — Kubota's RTV-X900 uses a reliable diesel engine and a hydrostatic transmission (no CVT belt to burn) plus optional hydraulic dump bed, making it a genuine mini-truck for serious property and farm work. It's slow but immensely durable. Verify the diesel service, hydrostatic transmission, and dump/hydraulics. A documented Kubota RTV is a supremely dependable, no-belt work machine; the diesel and hydrostatic checks matter most.
