Engine

Kubota's cutting-edge diesel engine technology is world famous. So, it's no surprise that the engineers delivered again on the new Grand L30 engines. Improvements start with balancers and larger displacement for increased power output and higher PTO torque, even with heavier loads or at lower speeds. In addition, this ultra-quiet engine produces cleaner emissions with less vibration. That's why for the ultimate in performance and reliability, day in and day out, Kubota diesel engines are simply the best.

E-TVCS Diesel Engine Kubota's Three Vortex Combustion System (E-TVCS) provides increased air flow into the combustion chamber, where it then mixes quickly and evenly with fuel from the fuel injection nozzle to produce greater power, efficiency and cleaner emissions. This diesel engine system found in the new Grand L30, exceeds CARB (California Air Resources Board) certification for ULG (Utility, Lawn and Garden engines below 25 hp), considered the world's most stringent regulation for diesel emissions. What's more, surpassing these Tier-1 regulations or cleaner emission means the Grand L30 is suitable for livestock work.	High Torque Rise The Grand L30's dependable E-TVCS engine delivers an increased airflow to its combustion chamber, where it then mixes evenly with fuel from the fuel injection nozzle. This system provides users with a sustained higher torque rise, under heavy loads as well as at lower speeds, for optimum performance.	Low Noise and Vibration The Grand L30's improved engine design also decreases noise and vibration levels, which help to reduce operator fatigue, especially when the job requires long hours. In fact, Grand L30 engine noise and vibration levels are significantly lower than those of competitors' conventional direct injection systems.
