How do you adjust the tension belt on a craftman dyt 4000?

To adjust the tension belt on a Craftsman DYT 4000, first, ensure the mower is turned off and the key is removed. Locate the tension adjustment mechanism, usually found near the engine or under the mower deck. Use a wrench to either tighten or loosen the tension adjustment bolt, which will change the tension on the belt. After making the adjustment, check the belt's tension by pressing down on it; it should have a slight give but not be overly loose.
