Powered by a proven Kubota 108 HP diesel engine, available with an all-weather cab, and built from the hardest working materials around, the M108S is a mid-size ag workhorse packed full of high-performance and lasting durability. Plus, working with a full line of performance-matched implements is made easy thanks to a standard Category II, 3-point hitch with up to 7,490 lbs. lift capacity.

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.

M108S Engine

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.

Swing Shift

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.

Hydraulic Brakes

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).

Extended Wheelbase

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.

Tire Options

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).

Independent PTO

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. 

Heavy-duty Drawbar

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.

M108S Front Loader (LA1403)

With a host of convenient options, Kubota's powerful and versatile front loader lets you take on a wide variety of chores.

Lifting Power and Height Adjustments

Two separate boom cylinder fulcrum points (Power position and Height position) give you the option to increase the loader’s lifting power or height based on your needs. When using the pallet fork or bale spear you may want to set the fulcrum to give you more height. For bucket work, a lower setting offers more power.

Protected Cylinder Tubes

To protect the tractor’s hydraulics and offer the operator greater visibility, we’ve neatly tucked the hydraulic tubes inside the loader’s boom. Hydraulic tube covers provide further protection from wear and tear.

Frame Design

The loader’s thick steel frame has been simplified by removing braces and connectors. This redesign reduces the effort and time it takes to attach the loader and offers increased visibility.

Quick-mount Attach/Detach

Attach or detach the front loader with ease and without the use of tools. Simply utilize the boom stand and mounting pins to quickly ready your tractor for its next job. A single-lever Hydraulic Quick Coupler (optional), available for the loader’s hydraulic fittings, allows you to release all four lines at once.

Joystick Control

The joystick offers you the ability to control the movement and speed of the loader with a single lever. The joystick tower also adjusts vertically, towards or away from the operator, and locks in place. This allows you to easily find your best working position. The Series Circuit makes simultaneous boom and bucket operation possible, while the Regenerative Bucket Dump Circuit enables quick dumping for efficient operation with quick cycle times.

4-bar Linkage

The 4-bar bucket linkage increases the rollback and dumping angle for quicker scooping and dumping.

Bucket Design

A recent design improvement in the loader bucket is its round back. This feature increases the durability of the bucket, helps keep wet materials from sticking in the corners and makes dumping sand and soil easier.

Rubber Caps

Rubber caps help to prevent grease drips, keeping the operator’s clothes clean. They also give the loader a more appealing look.

Skid Steer-type Quick Coupler

A standard feature on the M108S loader, this coupler makes attaching and detaching buckets, bale spears and pallet forks as easy as can be.

Kubota Shockless Ride (KSR)

The KSR helps to minimize fatigue by “smoothing out” the ride of the tractor. This feature is particularly useful when your tasks include a lot of tight turns or lifting and dumping of heavy loads. It makes handling round bales far less jarring.

Single-lever Hydraulic Quick Coupler

The optional quick coupler allows the operator to attach all four hoses at once. This makes attaching and detaching fast and easy, even when you’re doing it often.

3rd Function Valve

Operated with buttons located on the grip of the joystick, the 3rd function valve broadens the capability of the front loader. It also enables the simultaneous operation of the bucket and loader boom, allowing smooth and easy operation.

Hydraulic Self-leveling Valve

This optional feature allows the operator to raise or lower the loader boom without changing the angle of the bucket. This will help prevent spills when carrying soil or sand and will make pallet handling smooth and easy.
