The shaft is rotatably mounted in a plastic cradle, and a spring steel plate is releasably retained in the cradle with a snap action and is traversed by slots in which the chopper blades turn. A hopper which is also plastic is pivotally mounted on the cradle and is releasably retained in upright operative position by a leaf spring carried by the hopper and engageable with projections on the steel plate. The hopper has depending ears that releasably retain the shaft in the cradle so that the shaft and blades can be removed when the hopper is swung open.
