Abstract
A mower deck assembly including a unitary housing with an upper, dome-shaped portion is fabricated from a plastic or laminate material. A modular drive including blade spindles and a belt drive is assembled onto a rigid flat metal suppport plate, and the plate is lifted into position within the housing with the drive received within the dome shaped portion. The support plate is fastened to the housing, and is isolated therefrom with elastomeric material to reduce noise and vibration and seal out dust. The dome-shaped portion and the plate define a drive housing which encloses the drive and protects the spindles and belt drive from the environment. The plastic or laminate material can be easily and inexpensively formed to provide the curved surfaces and the like for the housing with the loading being absorbed by the metal support plate.
