Introduction
Kubota M6800 Utility Tractor
The Kubota M6800 is a utility tractor produced between 1997 and 2005. Designed for versatility in agricultural and property maintenance applications, this series was manufactured in Japan to serve as a reliable workhorse in the mid-horsepower segment.
Engine and Performance
The tractor is powered by the Kubota V3300, a 3.3-liter, 4-cylinder liquid-cooled diesel engine. It generates 70.9 hp (52.9 kW) at a rated speed of 2600 RPM. The engine features a dual dry element air cleaner to protect internal components in dusty environments and operates with a compression ratio of 22.6:1.
Transmission and Drivetrain
Operators can choose between two transmission configurations, both providing 8 forward and 8 reverse gears. The synchronized shuttle version uses a 274.3mm cerametallic dry disc clutch, while the power shuttle model utilizes a hydraulic wet disc clutch, allowing for smoother directional changes.
Hydraulics and Hitch
The M6800 employs an open-center hydraulic system with a pump flow capacity of 11 gpm (41.6 lpm). The rear hitch is a category II/I type, equipped with position control and top-link draft sensing. It provides a tested lift capacity of 2,760 lbs (1,252 kg) at 24 inches behind the lift point.
Mechanical Features and Dimensions
Available in both two-wheel and four-wheel drive configurations, the tractor features power steering and a mechanical rear differential lock to manage traction. The operator station is equipped with a two-post folding ROPS as standard, with an optional climate-controlled cab available for increased comfort.
Conclusion
The Kubota M6800 is a robust utility tractor suited for varied farming tasks, offering a balance of mechanical simplicity and performance. Its flexible transmission options and category II/I hitch make it a capable machine for standard implements and daily field operations.
