Speed for a tractor is not the most important indicator, especially when working in the field. Speed is important when moving from one arable land to another. Higher speed means less time spent moving. There is a saving of money.
Experts have created the top fastest tractors in the world. The list includes both mass-produced tractors and one-off units made by passionate people.
The cars in the top will be presented in order of increasing speed.

The fastest tractor in the world
Speed is one of the most important indicators of any equipment, which is successfully implemented both in mass-produced tractors and in single copies of equipment created for participation in competitions and races.
One of these machines, which has been participating in racing since 2002, is considered to be a high-speed tractor built on the basis of the domestic MTZ-80. It is produced by Rostov, the organizer of Russian tractor races. Incredibly, during tests on ice, this agricultural machinery reached 120 km/h, which, according to experts, is not the limit for this “colossus.”
How does a racing tractor differ from its serial MTZ counterparts? Firstly, it is a 4-cylinder engine with a power of 200 hp. The gas tank was moved forward to prevent it from tipping over. The standard steering wheel was replaced with a steering gear from Mitsubishi Pajero, and the front suspension was replaced with a racing one from NISSAN PATROL. To better maneuver when cornering, the tractor acquired disc brakes and a hydraulic clutch. The modernization also affected the body. Instead of a cabin, a rigid frame appeared on which the driver's seat was fixed.
And although such a tractor is absolutely ineffective for a summer house or garden, the goal of its creators was achieved: now it is one of the nominees for the Guinness Book of Records.
But among serial products there are also leaders. For decades in a row they have been tractors from the British corporation JCB. Among its range, the Fastrac series is recognized as the fastest - 8 different models with a potential of 160-260 hp. Moving on public roads, such a tractor reaches a speed of 70 km/h, being on par with passenger cars.
Features of Fastrac tractors:
- wheel formula 4x4;
- differential lock;
- Cummins engines;
- ergonomic cabin;
- large diameter wheels.
Crawler tractors from the USSR era
Tracked vehicles from the times of the USSR could not boast of high speeds. The popular DT-75 traveled at a maximum speed of 11.18 km/h, the T-4 was slightly less - 10 km/h. These speeds were sufficient for plowing or harrowing work. But when it came to moving equipment between fields or to the farmyard... it was a bit difficult to drag along at such speeds. The record holder in those days was the T-150 , capable of accelerating to 15.65 km/h .

The most powerful tractor in the world
The ranking of the most powerful tractors in the world is headed by the Japanese tractor with a bulldozer blade - “Komatsu” D575A-3 SD, which is popularly nicknamed “Super Bulldozer”.
His area of specialization is construction and mining work in harsh conditions:
- ground leveling;
- transportation of earth masses, rocks;
- digging pits, trenches and their subsequent filling;
- development of metal, construction, fossil fuels; implementation of mining reclamation.
Structurally, it is a tractor with caterpillar propulsors, in front of which a blade blade is installed. Its layout was created back in the early 80s, and serial production began only in the early 90s. Since then, these tractors have conquered the quarries of Australia, Canada, and America. Ideal for the climate of the Far North, where they have no equal.
Technical features
Weighing 114.5 tons, the dimensions of the tractor are 11.7 x 3.2 x 4.8 m. The ground clearance is 74.5 cm, which allows you to move over uneven and blocky surfaces without damaging the underbody.
The role of the power plant is performed by a 1167-horsepower standard SA12V170E engine with 12 cylinders, turbocharging and a cooling radiator. In order not to be distracted by refueling, there is a 2.1 cc gas tank.
The tractor is equipped with a Komatsu TORQFLOW multi-stage transmission, which allows you to move both forward and backward. For each direction, the operator can choose one of 3 speeds.
Operating parameters:
- Soil pressure – 159 kPa;
- Forward/backward speed (max.) – 11.6/13.3 km/h;
- Blade dimensions – 74 x 36 x 80 cm;
- Hydraulic pump capacity – 1.26 m3/min.
Gearbox design and diagram
The gearbox provides not only gear shifting, but also the functioning of mounted mechanisms and units. For this purpose, a PTO (power take-off shaft) is provided, which is located on the side.
If you look at the gearbox in a longitudinal section, you can see two adjacent shafts: the primary and secondary. Both mechanisms are installed on the same axis and are connected to each other through a support bearing.
The 3rd, 4th and 5th speed drive gears are located on the input shaft. Connection type: spline. In addition, the input shaft is connected to the creeper gearbox through a gear wheel. The intermediate shaft is equipped with a gear, which meshes teeth with the gear of the third speed gear.
The intermediate shaft rotates due to a bushing installed in the bearing race. The bushing is connected to the central gear of the second gear stage. Behind this gear are located the cams of the power take-off shaft.
Gearbox MTZ-80
In addition, a lubricant spray system is installed above the main gear of the gearbox of the MTZ-80 tractor and the subsequent analogue MTZ-82. If you do not lubricate the rubbing parts, the tractor will quickly fail. This is an axiom for any machine operator.
The MTZ-80 tractor and the MTZ-82 model are equipped with a 2-stage reduction gearbox. It is added to the gearbox; the connection diagram is given above. The first gear stage has 1-5 speeds and one reverse mode.
Other operating modes occur at a different gear stage. The first gear stage is activated by engaging the drive gear with the crown of the secondary shaft. The second stage is engaged as a result of the gear meshing with the first stage gear.
The largest tractor in the world
Today, the list of the largest tractors can include at least ten models of agricultural machinery, including TERRION ATM 7360, Massey Ferguson MF 8690, Claas Xerion 4500, Komatsu D575A, Challenger MT975 B, etc. But the championship deservedly belongs to the American brainchild - “Big Bud-747”. Translated from English. it means "Big Buddy".
This record holder was released in 1977. It was created by special order and in a single copy for processing California cotton fields. But, despite this, the state of Montana is still considered his homeland.
The dimensions of the unit are impressive. The height of this 2-frame structure is about 4 m, and the width is slightly more than 8 m. To maintain balancing properties and ensure trouble-free movement, 8 wheels are provided instead of the traditional 4.
Considering that even a 5-furrow plow on a MTZ tractor covers only 3 m of field area, this giant can easily pull a 30 m plow. This allows you to cover about 400 hectares in a day, plowing them to a record depth of 120 cm.
Today “Big Bud” is a well-deserved exhibit of the American Heartland Acros Museum, which has no analogues in the world.
Technical characteristics of "Big Bud-747":
- 16-cylinder engine from Detroit Diesel with 900 hp;
- diesel consumption – 295.5 l/min;
- gas tank - 2.8 thousand liters;
- multi-stage transmission 6F + 1R;
- 2.4 m tire diameter;
- an effective air braking system copied from trucks and implemented on all 8 wheels;
- weight – 43 tons.
