KUBOTA M6800 ENGINE
The Kubota M6800 features a robust 3.3L 4-cylinder diesel engine, providing a balance of power and fuel efficiency ideal for medium-duty agricultural tasks. Two fuel tank options (ROPS: 17.2 gallons, Cab: 25.1 gallons) cater to different operational needs; the larger cab tank extends working hours between refueling, enhancing productivity. However, operators must consider the trade-off in weight and maneuverability with the larger tank during transport and field use.
