In heavy equipment listing a Bulldozer will be found at the top. Bulldozers or Dozers are heavy motorized machines equipped with a metal blade to push materials during construction work or so on.

Caterpillar and Komatsu are the two most heard names for a large dozer in any project. Both of them feature powerful engines and build.

Since a dozer is used for heavier jobs like pushing larger stones and digging a hard surface, they need to be built over a stronger module and the power terrain should exceed the most horsepower.

Today, we will be discussing both models to identify the greater one in terms of size and power.

Komatsu D475A

The Japan-headquartered automotive manufacturer brand is known for its huge production of dozers and track loaders. Even the largest bulldozer of the time, the D575A-3SD is from Komatsu!

D475A is the 2nd largest mining dozer by Komatsu. The giant company has its branches all across the globe. D475 is the upgraded model of the D375A and offers more efficiency with both fuel and transmission.

The D475A-8 is the last and most upgraded version by Komatsu. Hence it offers a few advancements in order. The latest one offers 10% more productivity and 10% less fuel consumption. The engine power is now enhanced by 11% more to provide more energy to the dozer.

Let’s have a look at the key specifications first. This will make the difference much easier.

D10 was the first dozer by Caterpillar. The D11 is the refined and redesigned version of the older D10. Upgrading with a bigger blade and larger track the Cat D11 ensures more efficiency.

These dozers are also used as Carry-dozers and can do the job of pushing and carrying goods and heavier items with the blade. The current models were introduced in 2008. These days you will find a D11T or a D11T CD in any massive construction.

Caterpillar Dozers are equipped with a powerful diesel engine and feature many advantages with the latest features included in the system.

The overall aggressive look of the bulldozers is more refreshing. The yellow machines are a hell of a working tool with the largest engine body with enormous power included in the engine.

Specs given on top of the article and this vary one above surely made a choice easy. See, performance-wise, the Komatsu D475A is a winner. On the other hand, the D11 provides you with power and efficiency at a lower cost. Yet both the dozers are competing for head to head.

But, if I were asked to pick one, the D475A would be the choice. If you choose medium or cheap price you can choose John deere 325g.

Final words

For the reason that we already have asked for their opinion, we fortify our readers to select the option that feels most encouraging for them.

Looking over the specifications and the overall performance of each of the Dozers, it is seen that Komatsu is leading in most cases. Though, purchasing one will be affected greatly by the figure cost. Thus, we are certainly not offering which one is the best value for money.

Yet, the Komatsu D475A is at the top of both.
