How do you adjust the tracks on a Dresser TD7E Bulldozer?

To adjust the tracks on a Dresser TD7E Bulldozer, first, ensure the machine is on a level surface and the engine is off. Locate the track adjustment bolts on the idler assembly and use a wrench to loosen them. Then, either add or release tension to the track by adjusting the idler's position, ensuring there's approximately 1-2 inches of sag in the track. Finally, retighten the adjustment bolts and check the tension again before operating the machine.
