In the video, a person is operating a yellow bulldozer. The bulldozer is equipped with a large front-loading bucket, which is used to scoop up a pile of dirt. The operator then maneuvers the bulldozer towards a dump truck, which is parked nearby. The bulldozer's bucket is then raised, and the dirt is dumped into the bed of the truck. The process is repeated several times, with the operator skillfully controlling the bulldozer to load the dirt into the truck. The video provides a clear view of the bulldozer's operation and the process of loading dirt into a dump truck.
