Kubota's reputation for making exceptional engines has never been more evident than in the Grand L40. Kubota's Three Vortex Combustion System (E-TVCS) allows for increased airflow into the combustion chamber, where it mixes quickly and evenly with fuel from the fuel injection nozzle to deliver exceptional power and efficiency. This resourceful system provides the user with a sustained higher torque rise, under heavy loads and at lower speeds, for optimum performance. Furthermore, the Grand L40 tractors boast engines that produce clean emissions, complying with EPA Interim Tier IV standards and emit minimum noise and less vibration, helping to reduce operator fatigue and stress.
