A Cover, Case, or Housing refers to parts covering and protecting larger components of your model, such as the Clutch, Deck Belts, Transmissions, or Controls. These can be synonymous with a Mower Deck Shell, Scabbard or more specific components to your model. A cover can be made of hard plastic or metal. Some covers can wear down over time from collisions or large debris, and it is important to replace if needed for user safety and the protection of parts from debris and chemicals.
