World’s Top 10 biggest bulldozers (update 2024)

By Patrik Eder and Florentina Chiriță · Published: May 25, 2021 · Updated: September 24, 2024

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.

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.

Bulldozer SD90-C5 is the biggest mining dozer from the Chinese manufacturer Shantui and occupies the 5th place in our ranking. The flagship model weighs over 106 tonnes and delivers a performace of 708 kW (962 HP) when equipped with Cummins QST30 electronic control engine. The operator's cabin was designed with focus on ergonomy, visibility and noise reduction (80 dB). The SD90-C5 can be equipped with either semi-U blade or U-blade attachment. The first tool achieves a digging depth 1,010 mm and the single-shank unit (ripper type) offers even 1,670 mm of digging depth. The bulldozer is huge and its sizes are 11.5 x 5.26 x 4.59 metres (l x w x h).

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.

Operating Weight	112.62 t
Engine Power	777 kW (1040 HP)
Blade Capacity	34.4 m³

Length	11.3 m
Height	4.8 m
Width	5.43 m

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.

Operating Weight	112.72 t
Engine Power	695 kW (913 HP)
Blade Capacity	43.6 m³
Blade Size (length x height)	6.7 m x 2.95 m
Length	10.71 m
Height	4.72 m
Width	3.81 m

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.

Operating Weight	152.6 t
Engine Power	858 kW (1150 HP)
Blade Capacity	69 m³
Blade Size (length x height)	7.4 m x 3.25 m
Length	11.72 m
Height	4.88 m
Width	7.4 m

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?

Operating Weight	183 t
Engine Power	1010 kW (1350 HP) (505/675 x 2 engines)
Blade Capacity	25.5 m³
Blade Size (length x height)	7 m x 2.7 m
