Electric tractors – Sustainable and Profitable? Economic and environmental impact of autonomy and electric drivelines in agriculture

• Vehicle electrification can be an effective emission-mitigating technology in heavy vehicles, including in agriculture. Simulation was used to assess the effect of switching conventional diesel tractors to multiple lighter autonomous battery-electric tractors on a Swedish grain farm. An autonomous diesel tractor was also considered. An LCA was made to assess environmental impacts, and the annual cost was calculated. The electric scenario had a 65% lower climate impact than its diesel counterpart and had a reduced the annual cost by lowering operator, fuel and maintenance cost. In total, the cost was lowered by 31% from the conventional scenario. In both the environmental impact and cost, fuel played an important role.
