A bulldozer provides improved visibility in front and/or rear of the bulldozer. The bulldozer includes an engine arranged in the front of the bulldozer and a cooling module for cooling the engine arranged elsewhere in the bulldozer, such as behind driver's seat. In the bulldozer, the arrangement of the engine, the vehicle, and the cooling module provides improved visibility in front of the bulldozer so that the operator of the bulldozer can view the upper middle portion of the bulldozer blade.
