Introduction

Kubota M108S Row-Crop Tractor

The Kubota M108S is a row-crop tractor produced between 2007 and 2014, designed to provide reliable performance for diverse agricultural applications. It is built around a liquid-cooled, 3.8-liter turbocharged intercooled diesel engine, positioning it as a versatile utility machine for medium-to-large farming operations.

Engine and Performance

The tractor is powered by the Kubota V3800-DT-TI 4-cylinder engine, which generates a net power of 108 hp (80.5 kW) at a rated speed of 2600 RPM. This engine incorporates an exhaust gas recirculation (EGR) system to meet Tier III emission standards and utilizes an intercooled turbocharging system to optimize combustion efficiency.

Transmission and Drivetrain

The M108S offers significant flexibility in power delivery through various Swing Shift transmission configurations. Options range from a 16-speed partially synchronized transmission to a 48-speed partial power shift system with creeper capabilities. All models feature a hydraulic shuttle and wet disc clutches, available in both two-wheel and four-wheel drive variants.

Hydraulics and Hitch

Equipped with an open-center hydraulic system, the tractor provides a total flow of 29.3 gpm (110.9 lpm) at a pressure of 2844 psi. It supports one to three remote valves. The rear Category II three-point hitch offers a lift capacity of 5,560 lbs at the ends, ensuring compatibility with a wide array of implements.

Operator Environment and Dimensions

The machine is available with a two-post foldable ROPS or an optional climate-controlled cab featuring heat and air conditioning. It features hydrostatic power steering and hydraulic wet disc brakes. Depending on the configuration, the tractor width varies, with 4WD models providing an adjustable rear tread width between 68.1 and 80.1 inches.

Conclusion

The Kubota M108S is a robust row-crop tractor suitable for farmers requiring a balance of power, maneuverability, and transmission versatility. Its range of gear options and hydraulic capacity make it well-suited for varied field operations, from precise planting to heavy traction tasks.
