The Caterpillar D9 bulldozer
There are plenty of bulldozers on the market but not many perform quite as well as the Caterpillar D9. This really is a bit of a beast when it comes to shifting earth, and it’s regularly used in the military.
It has proved to be extremely effective for the Israeli Defence Forces, while the US Army used these machines in the Vietnam War, yet they were replaced soon after with cheaper and more compact alternatives.
The D9 is still regularly used in construction as well as waste and quarry operations, and that’s because of its low operating costs, as well as its exceptional performance. There aren’t many machines on the market that can bulldoze better than the C9, and these machines will surely still be used 20 years or so down the line.
