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
