4-cylinder Kubota Diesel Engine (V3800)
The M108S is built with the power and durability to take on even the most heavy-duty tasks. This is due to its 4-valve, Electronic Center Direct Injection System engine, which help to realize greater pulling power.
The engine of the M108S has been redesigned and reengineered. Of course, it boasts the same durability and quality you’ve come to expect from Kubota E-CDIS diesel engines. But, this new turbocharged engine is now cleaner than ever before, offering higher torque and incredible pulling power. The CRS (Common Rail System) and Cooled EGR (Exhaust Gas Recirculation) System reduce emissions, helping with compliance to U.S. EPA Tier III emissions regulations. We’ve increased horsepower to 108 on the M108S and PTO power from 93 to 96HP. These are big changes for a big tractor, and ones you’ll certainly observe out in the field.
CRS (Common Rail System)
Typically found in automobiles to help reduce emissions and decrease fuel consumption, CRS has been implemented on our M108S engine to accomplish the same results. The CRS electronically controls the timing and amount of fuel injection. By delivering high-pressure injections in stages, rather than all at once, an optimal combustion rate is achieved, thus offering greater efficiency in the cylinder. This equates into less combustion noise, commonly known as "diesel knocks", better fuel efficiency and cleaner emissions. By controlling the amount of fuel injection, the CRS also serves to provide greater torque so that operations in the mid-to-high revolution range, such as baling, can be performed more smoothly.
Cooled ERG System
Our Cooled EGR (Exhaust Gas Recirculation) System aims at the same end as the CRS; to reduce noxious emissions. Specifically, the Cooled EGR System reduces smog-producing nitrogen oxides by lowering the combustion temperature. It accomplishes this by diverting exhaust gas through a cooler and then returning it to the combustion chambers, where the cooled gases minimize temperatures and hamper nitrogen oxide formation.
Our “Swing Shift” gives you access to a total of 16 speeds! The synchronized main shift’s “H” pattern puts four speeds immediately at your disposal. The Swing Shift adds to that by actuating the electric-over-hydraulic high/low synchronized range shift for a total of eight speeds—all controlled by a single lever. If a task requires more than eight speeds, simply move the auxiliary range lever left of the seat for eight more to equal 16F/16R. An optional, simple-to-install, cassette-type creep provides eight additional slower speeds. That’s 24 speeds—enough for the most demanding and precise work.
Swing Shift Plus with Dual Speed
Swing Shift Plus models give you 32F/32R speeds, and allow you to operate the Swing Shift as well as the Dual Speed with just one lever. Should your load suddenly get heavier, just push the Dual Speed’s high/low button while still in motion. Your speed will reduce by 17%, but lugging force will dramatically increase. Put this feature to best use when taking on large load increases, when working in mixed soil or during hay tool applications. Combining the Dual Speed with the optional creep provides 16 additional slower speeds—a total of 48F/48R—for specialty applications (Swing Shift Plus with Dual Speed not available on all models. See specs for details).
Hydraulic Shuttle Shift
Mounted on the left side of the steering column, the shuttle lever’s fingertip control makes it possible to shift smoothly from forward to reverse without using the clutch or stopping the tractor. This makes front loader operation significantly easier.
Multiple Wet-disc Main Clutch
Our multiple wet-disc main clutch ensures smooth and effortless operation and offers greater durability.
All it takes is a light touch to activate these highly responsive, hydraulic, wet-type brakes. This feature helps to reduce operator fatigue.
Easy to Shift 4WD Engagement
Stay moving and stay productive by switching the 4-wheel drive on and off without stopping, even when moving out of a field onto a road (do not engage while carrying heavy loads, or when a rear wheel has lost traction).
The extended wheelbase gives these tractors a lower center of gravity, directly equating to exceptional stability and pulling power.
Heavy-duty Front Axle
The M108S is equipped with a rugged front axle found on larger tractors. So you can rest easy knowing that you can count on reliable performance, even when using the front loader.
To enable the M108S to perform its best, we offer a variety of tires, including cast iron discs.
Slanted Full-open Hood
The slant-nosed, full-open hood design makes maintenance a snap, as the one-piece hood’s dual gas shock assist enables it to lift up easily. This design feature also improves operator visibility over the center of the tractor hood for safer and more efficient working conditions. The curved design also provides a sleeker overall appearance.
Air Cleaner with Built-in Pre-cleaner
This air cleaner will help protect your engine when operating your Kubota M108S in particularly dirty or dusty areas.
New Halogen Headlights with Corner Lamps
We've mounted the headlights high to improve visibility, even during loader work. These halogen lights with corner lamps are efficient and provide excellent illumination.
Auxiliary Remote Control Valves
One remote valve (SCD) is standard on the M108S. With the optional flow control valve installed, you can simultaneously operate the 3-point hitch and one remote valve, or two remote valves. Up to three remote valves can be installed in total. *SCD valve (standard) and Flow Control Valve with SCD (optional).
The PTO clutch enables the implement drive system to engage smoothly, which helps reduce operator fatigue. And because the PTO is independent, you don’t have to stop the tractor to engage or disengage the PTO, saving time no matter what the task.
Floating Lift Rods
Floating lift rods are standard on the M108S. The floating position offer a smoother ride and enhanced traction while using the 3-point hitch, especially on uneven terrain.
Cat. II Hitch (Telescoping Links Standard)
The category II 3-point hitch provides fast and easy attachment of rear-mounted implements. The hitch’s telescopic stabilizers and lower link ends make hook up and adjustments simple and worry-free.
This rugged and dependable drawbar, usually found on higher-end models, has the muscle it takes to tackle your toughest tasks, such as pulling heavy trailers.
Instrument Panel with LCD Readout
The new instrument panel makes viewing the vital functions of the tractor clear and easy. The LCD readout displays travel speed, PTO revolution and hour meter information digitally. Illuminated analog indicators include a large tachometer, temperature gauge and fuel gauge. A battery warning light has also been added to these tractors to prevent surprise battery failures, as well as indicator lights for 4WD engagement, PTO and oil pressure.
Easy Step Tilt Steering Wheel
Find the position most comfortable for you. Step on the pedal; tilt the wheel to select from among six wheel positions, and then lock it in place. Simply step on the pedal again to unlock the wheel for easy tractor mounting and dismounting.
Foldable ROPS (ROPS Model)
A foldable Roll Over Protective Structure (ROPS) comes standard on the M108S. The ROPS can easily be folded down without tools so that the tractor may pass under areas with height constraints, such as doorways or low branches. (There is no operator protection provided by the ROPS in the folded position. For operator safety, the ROPS should be placed in the upright and locked position and the seat belt fastened for all other operations.)
Extra-wide Operator Platform
The M108S boasts a wide platform that offers more legroom for greater operator comfort.
