Building huge structures or working in big mines and quarries sets very high demands on the size, performance and reliability of machines that are used to do the hard work. And there is only one type of equipment that can completely meet them: bulldozers. The world’s largest bulldozers, to be exact. These giant machines that lead the way on the jobsite are the only ones technically equipped to deal with the harshest working conditions and with a lot of difficult operations: pushing large quantities of soil, sand, rocks or debris, digging, excavating and levelling materials. And when it comes to crawler dozers, bigger is, indeed, better. Big crawler dozers are far more efficient than any other machine. They push more material per hour and have all that it takes to move or demolish basically anything that stands in their way: huge dimensions, super powerful engines and blades that can be tilted, lifted, angled and pushed forward or backward in order to complete a variety of difficult tasks. But what makes these machines even more special is the amazing trio blade-ripper-tracks that works its magic when put to work: while the blade moves material from one place to another, the ripper breaks the ground, making it easier to work with, and the tracks generate excellent ground hold and weight distribution, preventing the bulldozer from becoming stuck or to slip on difficult terrain. We did some…digging, as well, and found out who holds the title for the largest and most powerful dozer ever built. Check out our Top 10 biggest bulldozers in the world, according to operating weight and engine power/dimensions.

10. Caterpillar D10T2 – Strength from the past, power for the future
If our Top 10 would have been made in 1970, Caterpillar D10T2, our 10th biggest bulldozer in the world, would have been at the top of the list. This beautiful piece of machine that brings strength from the past and power for the future holds a lot of nostalgia behind it. It was born from Caterpillar’s engineers ambition to come up with a bigger and more powerful dozer than the ones that its competitors were building at that time, and also than the previous model, Caterpillar D9. And their efforts paid off: When it was introduced by Allis Chalmers, at Conexpo, in Chicago, in 1969, as the HD-41 (391 kW / 524 HP), the now D10T2 was the largest crawler dozer in the world and the first tractor to use the elevated drive sprocket. From the moment it was first launched and until now, Caterpillar D10T2 has undergone many technical transformations, but did not disappoint once: it turned out to be exactly the highly productive and versatile machine, engineered for demanding work, both flexible (to be used on heavy construction sites) and robust (to be used on mine sites), that everyone expected it to be. This machine of 70.17 tons is well suited for tough working conditions. The durable construction, the 766 HP engine and the 18.5 m3 capacity blade keep the material moving with the reliability that is so specific to Cat dozers.

9. Chetra T40 – The most powerful Russian dozer
Number 9 in our Top 10 biggest bulldozers in the world, CHETRA T40, is the most powerful serial Russian bulldozer made for the gold and coal mining industry by the Concern Tractor Plants manufacturer, a specialist in heavy duty machinery. This strong machine stands out from the entire range of crawler-type dozers not only by its heavy weight of 70.28 tons, but also by the bogie-type undercarriage, specially developed to ensure the best traction when dealing with very rough working environments. In combination with the powerful engine rated at 660 HP and the supersize blade with a capacity of 21 m3 that gets the work done on the jobsite, CHETRA T40’s technical features provide the utmost efficiency, keeping, at the same time, the operator safe and comfortable while operating this large dozer. Like all the other CHETRA bulldozers, the T40 is a fusion between the traditional Russian reliability in frame & undercarriage materials and the high efficiency of hydraulic components from American and European suppliers. And, since the hydromechanical or hydrostatic transmission of bulldozers no longer require physical strength from the operator, today, CHETRA T40 can be easily controlled by fingertips, which makes this super bulldozer even more appreciated by operators.

6. Fiat Allis HD-41 (FD50) – Caterpillar’s first worldwide famous dozer
The first version of the now Caterpillar D10T2 model, our 6th biggest bulldozer in the world, made a huge impression on the market at the Chicago Road Show in 1969, when it was released, being described as the largest dozer ever built at that time. Its amazing ripping capabilities were exactly what contractors from large earthmoving, surface mining and quarry applications were waiting for. Weighing 80 tons and being powered by a 524 HP Cummins VT-1710-C four cycle turbocharged engine, Fiat-Allis, that was put in production in 1970, offered a semi-U, full U and cushioned push hydraulically controlled blades. The dozer featured a torque converter and a power-shift transmission with three speeds in forward and three in reverse. Attachments included bulldozer blades up to 20 feet wide in semi-U and full-U options and a cushioned push block for push-loading scrapers. Between 1970-1974, 1,900 units of Fiat-Allis HD-41 were built. After the joint venture with Fiat SpA, the machine improved into Fiat-Allis 41B which was launched in 1982, and later into FD50, equipped with a Cummins VT28-C engine. Unfortunately, due to market reasons, Fiat-Allis stopped production in 1989, but Fiat-Allis HD-41 continued to fascinate the public, as the world’s largest bulldozer, for a very long time.

4. Komatsu D475A-8 – A great combination of power and speed
This is the exact description given by Komatsu to this beautiful piece of big crawler dozer, one of the most famous in the world. Number 4 on our Top 10, the D475A-8 is the second biggest dozer model from the Japanese producer included in our ranking, which makes Komatsu one of the most important manufacturers of big bulldozers globally. The D475A-8 was launched in 2020 as the successor of the dash 5 model. With an operating weight of over 112 tons and an engine power of 777kW/1040 HP, that delivers excellent productivity, Komatsu D475A-8 might not be as strong as its bigger brother Komatsu D575A-3, but for sure is powerful enough to be recognized as one of the world’s largest production bulldozer on the market. The total length of 11.3 m and the 34.4 m³ blade capacity also helps this large Komatsu dozer to offer great technical performance in mining, heavy-duty and large-scale civil works. And superior tranquillity, thanks to its hydraulically driven radiator-cooling fan installed to assure optimum rpm, while drastically reducing noise. On top of that, the automatic torque converter lock-up system and the electronically controlled transmission designed to offer greater efficiency during long pushes make the Komatsu D475A-8 a superior crawler dozer in both ripping and dozing production. The first unit is currently in service at a large oil share quarry near Narva, Estonia.

3. Caterpillar D11T CD – The dozer that moves more for less
Number three on our ranking is not just one of the biggest bulldozers in the world, but also the largest Caterpillar dozer ever built. What makes CAT 11 TCD so great is the durability built in factor that helped this machine pass both the test of the most demanding applications and the test of time. According to the American manufacturer, the CAT 11 TCD large crawler dozer moves more for less, and has all that it takes to do that: an operating weight of 112.72 tons, a powerful engine of 695kW/913 HP and a strong blade made by high tensile strength steel, featured with a box-section that resists twisting and cracking, that can handle up to 43.6 m³ of material. And speaking of strength: One of the greatest features of the biggest Cat dozer is the mainframe, purpose built to absorb high impact shock loads and twisting forces during severe dozing and ripping applications. So, to see this machine rebuilt several times using the same frame, with only minor welding, it is not unusual. Another technical feature that makes CAT 11 TCD a super dozer is the torque divider between the engine and the transmission that reduces the possibility of damage to the power train by dampening impact loads and vibrations.

2. Komatsu D575A-3 SD (SUPER DOZER) – The largest dozer ever built by Komatsu
The second biggest dozer in the world is called SUPER DOZER for a very good reason: it has an operating weight of 152.6 t and, on top of that, it is powered by an engine that delivers no less than 858 kW/1150 HP at 1.800 rpm. So powerful that Komatsu engineers decided to mount it to the main frame with rubber cushions, in order to minimize the noise and the vibration. The impressive size of this giant bulldozer can be, sometimes, quite challenging: in order to be transported on significant distances, the machine needs to be disassembled and moved in up to 8 tractor trailer loads! A Super Dozer like Komatsu D575A-3 comes, of course, equipped with a Super blade with a capacity of no less than 69 m3 (extra holding volume) and an innovative design that makes it 15% more productive in level dozing. This means that the world’s second most powerful bulldozer can push a larger volume of material against the same soil resistance and it has an optimum balance for dozing. The fuel-efficient Komatsu engine, together with the heavy machine weight, makes Komatsu D575A-3 Super Dozer a superior machine in dozing production, and the main reason why it is mostly used in the most challenging mining and construction sites around the world. The largest dozer and the most productive ever made by Komatsu, was first introduced in a prototype form at Conexpo 1981, and was released as a production Dash 2 model in 1991. It was officially launched in 2002.

1. ACCO Super Bulldozer – The greatest dozer with the most incredible story
The biggest bulldozer in the world, according to our Top 10, has a story to match its impressive dimensions of 183 tons weight and 12 m length. Strange but true, this beast that the whole world admires even now, 40 years after it was built, has never moved a m³ of material in its life. ACCO Super Bulldozer was constructed in Portogruaro in northern Italy, by the Umberto Acco company, in order to be exported to Libya in the early 1980s. Due to the trade embargo restrictions imposed by the United States of America in 1986, on that country (caused by the involvement of Colonel Gaddafi, the leader of Libya at that time, in international terrorism), ACCO Super Dozer was never shipped to its destination and was put into storage. This biggest dozer ever built is mainly made of Caterpillar parts. The blade, for example, is bigger than anything Caterpillar has ever made: it is 7 m wide and 2.7 m high. The ripper alone of the world’s largest dozer is about 3 m tall, being operated by huge hydraulic rams. Putting such a large machine to work required a lot of mechanical energy, and it is no surprise that the strongest and the biggest dozer in the world is powered by two 675 HP (503 kW) Caterpillar engines placed horizontally opposed, that deliver a total combined output of 1350 HP (1010 kW)! Amazing, right?
