The Biggest Kubota Tractor 2023

To those who are passionate about machinery and agricultural machinery, I hope you are ready for the beast that I have chosen to present to you in detail.

Today’s machinery is the biggest Kubota tractor with its own series. Named Kubota M8, it is a heavy-duty tractor that will completely change your vision of how agriculture is done.

Now, let’s see all the features and technology that this tractor has to offer.

Kubota M8 Tractor Features

Having some unusual dimensions, it is quite clear that even in terms of features this big tractor will not disappoint.

At first sight, the tractor will leave you amazed with its cabin made entirely of glass. Those from Kubota described it as “your office, with the view”, and I am not arguing this because it is indeed right. This cabin has a 360° panoramic view and a roof panel with an unobstructed view.

To make the work of any operator even easier, the tractor comes with window defoggers, front and rear wipers, standard sun visors, and well as heated and power-adjustable mirrors, and rear visors as optional options. All these give the operator a clear and wide-ranging view, allowing for maximum visibility while operating the fields.

Inside the 145 cubic feet cabin, ample room for movement allows the controller to move freely.

At the same time, he can use the manual climate control system for an optimal temperature, but also the radio or A/C. There is also a power-ready USB port that can power multiple devices such as extra monitors, as well as a 12-volt power station just in case you want to charge your laptop while you work.

And, this is not all. What is missing? The chair’s features, of course. The Kubota’s seating has a standard pneumatic suspension that offers a feeling of softness and comfort.

Of course, this can be upgraded with the other type of suspension such as the semi-active one, but also with a package of leather covers with heating/cooling.

Command Center

To make all farming operations run smoothly and efficiently, it comes with some modern control applications that will assist you in all tasks. The tractor’s command center is a great tool that has been tailored with the operator’s convenience in mind, having a user-friendly interface and advanced functionality. This easy-to-use design maximizes the controller’s ability to perform.

Integrated technology

In addition to the command center, the biggest Kubota tractor features a standard 7″ K-monitor that can be upgraded with a 12″ LCD touchscreen display. Via the monitor, the following can be accessed: the system controls, the connectivity for cameras, and the ISO-BUS control.

The tractor’s compatibility with all industry farming solutions makes it perfect to be used in any farming scenario, while the Kubota Headland Control helps to create automatic operations.

With all these comfort and control features, the Kubota M8 really stands out as a top-of-the-line tractor.


The M8 tractor is manufactured by Kubota Tractor Corporation, which is headquartered in Grapevine, Texas.

This company has a reputation for producing also other high-quality farm tools and machinery. They even created a line of tractors of up to 170 HP, garden equipment, utility vehicles, and hay tools and spreaders.

Nevertheless, of all their products, Kubota M8 is one of their big tractors.

High performance transmission options


Those from Kubota wanted the M8 to have a powerful engine, friendly to the environment through less fuel consumption and lower emission, but to also reduce the cost of operation for farmers.

As a result, the Kubota M8 tractor is equipped with a Cummins B6.7 Performance Series engine. Believe me when I say that this engine is a real masterpiece built by Cummins, being even the most popular diesel engine from this company.

This six-cylinder, 6.7L engine has an EGR-free design, which reduces the cooling system space claim. Unlike the predecessor model, the Cummins B6.7 engine provides 5% more power and 31% more peak torque.

The Holset VGT variable-geometry turbocharger technology delivers superior performance across a wide range of engine speeds, improving its efficiency and overall responsiveness. For easy maintenance and installation, the engine components can be placed in different ways. For example, the pan locations can be placed in front-or rear sump, while the ECM and maintenance filters can be on-engine or remote options.

This engine is available in two versions, one of 180 hp and another of 200 hp.

This tractor boasts a fully electronically controlled Semi-Powershift transmission that is comfortable and convenient to use. This type of transmission offers 30 forward and 15 reverse gears, reaching a speed of 25 mi/h. Plus, there is a six-speed power shift with two of the gears overlapping, which means that you don’t have to change the speed that often during tasks.

Thanks to the all-purpose 4-speed PTO, you can use the economy mode to reduce fuel consumption and emissions.

This mode allows the engine to function at a suitable speed with a lower engine RPM. This specific function is located on the right side of the cabin. Also, the tractor comes with a left-hand lever and right-hand multi-function handle control for greater maneuverability.


The hydraulics are, as the engine, a dream of any tractor operator, or at least for me it is.

Playing a critical role in the operation of this machinery, the Closed-Center, Load Sensing (CCLS) hydraulic system ensures the right amount of pressure when controlling the movement of the attachments

Here, the tractor comes with a standard implement pump flow of 31.7 GPM, but you can always opt for the optional implement pump flow of 42.2 GPM. Same for the valves – standard 3 valves, and optional 5 valves.


When it comes to the hitch, this tractor comes with an optional Category III three-point front hitch and front PTO. It attaches quite easily and can lift a standard of 112000 lbs or upgrade to 13600 lbs. With this common three-point hitch it is easy to implement plows, mowers, or cultivators.


The tractor has an M77 loader that helps you move and transport all you want. The accessibility of the loader is simple. It is easy to handle it through an electronic Joystick control created by Kubota.

Also, the biggest Kubota tractor reaches a maximum lifting height of 181.2″ at the pivot and lifts 5490 lbs. Besides the impressive height, it also has other features such as a mechanical self-leveling system, and a loader suspension. The Kubota Shockless Ride(KSR) suspension system delivers comfort even on uneven terrain by absorbing shocks and vibrations.
