How does bulldozer drive line work to turn?

The bulldozer's drive line consists of two tracks, each powered by its own hydraulic motor or engine. To turn, the bulldozer varies the speed of each track; one track moves faster or is slowed down while the other remains at a different speed. This differential in speed allows the bulldozer to pivot around its center, enabling it to maneuver effectively. By controlling the power delivered to each track, operators can achieve precise movements and turns even in tight spaces.
