    Wow, interesting! Caterpillar has changed the names of its bulldozer models! How long ago did this happen?

    1. David R. Ledford (author)

      In 2020, Caterpillar revamped its bulldozer naming system to streamline machine designations. As a result, bulldozer names now exclude letter suffixes following the numbers, with each machine’s name directly indicating its power rating:

      CAT D3K becomes the D1
      CAT D4K becomes the D2
      CAT D5K becomes the D3
      CAT D6K becomes the D4
      CAT D6N becomes the D5
      CAT D6T becomes the D6
      CAT D7E becomes the D7
      CAT D8T becomes the D8
      CAT D9T becomes the D9
      CAT D10T becomes the D10
      CAT D11T becomes the D11

    If I choose the same type and size of bulldozer, which brand is better to buy – Caterpillar, Komatsu or John Deere?

    1. Jonathan Field

      I worked with CAT equipment for many years, so I would buy a bulldozer from this manufacturer!
