Transmission
F8/R8 Transmission. Synchronized four speeds of the main shift and a high/low range supply tractors with 8 Forward and 8 Reverse speeds.
The main shift allows you to shift "on the fly", making operation smooth. Tailor this transmission to your needs by choosing from a hydraulic or synchronized shuttle transmission.
F12/R12 Transmission. (Factory option on M8540/M9540 Hydraulic Shuttle models.) For heavy-duty work such as plowing, hay work and heavy trailer applications, the hydraulic-shuttle models of the M8540 and M9540 can be equipped with an F12/R12 transmission. This transmission features six speeds of the main shift and a high/low range giving it a total of 12 Forward and 12 Reverse speeds.

(M9540 Traveling Speed, F8/R8 with creep speed, 18.4-30 rear tires, @2600 rpm.)
The M-Series shifts into high gear.
Hydraulic Shuttle. (Hydraulic Shuttle models) Better than ever, Kubota's Hydraulic Shuttle for the M-Series makes shifting between forward and reverse smooth and quick. With the Hydraulic Shuttle, a column-mounted lever, conveniently located next to the steering wheel, does all the work. Boost productivity, especially while using loaders, by eliminating the need to depress the clutch every time you change directions. And when attaching implements, Kubota's improved inching feature is easy to perform, giving you the same feel as a half-clutch operation.
Synchronized Shuttle. (Synchronized Shuttle models) Shifting between forward and reverse is made quick and smooth with the M-Series synchro-shuttle, located within easy reach of the steering column. The M8540 and M9540 also offer greater durability with a new, larger diameter cerametallic clutch.
Wet Disc Brakes. (M8540 and M9540) To decrease operator effort and increase overall tractor longevity, the Kubota M8540 and M9540 now come standard withHydraulic Wet Disc Brakes. These brakes require less pedal effort and retain high performance efficiency even after repeated heavy-duty work.
Transmission Parking Lock. (M8540 and M9540) An easy-to-operate transmission parking lock, located beside the main shift, is now independent from the main brakes. This lock is highly durable and reliable, providing precise parking on any terrain.
Clutch. Built to extend clutch life, the main clutch in the synchro-shuttle transmission features cerametallic material of superb abrasion resistance. The clutch diameter is 10.8 inches on the M5040, M6040 and M7040, and 12.8 inches on the M8540 and M9540.
Limited Slip Differential. (M7040, M8540, M9540) Limited Slip Differential on the front helps you maintain a stable travel speed should the drive wheel on either side of the tractor slip. A standard feature on the M7040, M8540 and M9540, Limited Slip Differential is perfect when reliable traction is essential.
Convenient 4WD Engagement. Switching the 4-wheel drive on and off is easy and quick, and done with one simple lever. Best of all, there's no need to stop the tractor even when moving out of a field onto a road, so you can stay productive. (Do not engage while carrying heavy loads, or when rear wheel is spinning.)
