This dataset presents two Life Cycle Inventory (LCI) data of an agricultural tractor. The inventory takes into account the raw materials needed for the tractor manufacturing and maintenance over its lifetime as well as the energy and infrastructure needed for manufacturing. Calculations were made based on a tractor of 7300 kg with the following characteristics : 155 CV, 6 cylinders, four-wheel drive. Two LCI are produced : a LCI for a 7200 h lifetime tractor, representative of an accounting depreciation, and a LCI for a 12000h lifetime tractor, representative of the whole service life of the tractor (first use to final disposal). The functional unit is 1 kg of tractor (kg) or 1 piece (p) of tractor during its lifetime.
