World’s Top 10 biggest bulldozers
By Patrik Eder and Florentina Chiriță · May 25, 2021
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.

9. Dressta TD-40 - 67.7 tons of pure performance
With an operating weight of 67.7 t of pure performance and a net power of 515 HP, the TD-40 is not only one of the largest dozers in the world that made it to our Top 10, but also the heaviest and the most powerful crawler dozer ever built by Dressta. This large crawler dozer features a superior drawbar pull and an immense ripping performance that make it withstand the most challenging, abrasive tasks, so extreme duty construction, coal and mining jobsites is where this great machine feels at home. But what makes this giant bulldozer so durable? Well, a lot of things: the optimisation of weight distribution, the modular construction, the use of a one-piece main frame, the two-speed Steering Drive and the 3-point track mounting system. Optimal performance of Dressta TD-40 is also achieved by the standard Semi-U blade design that combines the penetration ability of a straight blade with the increased capacity provided by short wings, the adjustable parallelogram multi-shank ripper that offers excellent penetration in extremely tough material, and the high quality durable tracks for tough working conditions.

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.
|Operating Weight||112.62 t|
|Engine Power||777 kW (1040 HP)|
|Blade Capacity||34.4 m³|
|Blade Size (length x height)||6.21 m x 2.61 m|
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.
|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|
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.
|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|
1. ACCO Super Bulldozer - The greatest dozer with the most incredible story
|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|
