A tractor is a vehicle intended for drawing, towing, pushing or pulling something which cannot propel itself and, often, powering it too. In addition, tractor serves to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction. Tractors (one of which is pictured above) are available in sizes appropriate for farmers with 1 acre all the way up to those working 1,000 acres or more. You want one that has the right amount of horsepower and the right hitch rating for the work you plan to do with it.
