DI (Direct Injection) Engine
All of the four M40 Series tractors are equipped with Kubota's revolutionary centre-direct injection system (E-CDIS) engine.  The E-CDIS engines offer a rear combination of more power, durability and better fuel efficiency, so you'll be able to get the job done quicker and more efficiently while minding your budget.
These engines also boast lower noise levels, which equates to less stress and fatigue after long work days. 
Finally, all of Kubota's E-CDIS engines comply with EPA Tier II (Tier III on M9540 Cab) emission standards so you can rest assured you're running a cleaner engine.
