    Abstract: A paddle for a narrow canoe or kayak-type boat has a crossbar the end portions of which extend downwardly to create an inverted U-shape, with the blades being at the lower ends of U. Handgrips, preferably including either forearm rests or wrist rests for the tops of the forearms or wrists as well as handgrips, enable the user to operate the paddle in a broad sweeping motion, with both blades being inserted into the water and pulled back simultaneously, eliminating the yaw effect of either double-ended kayak paddles or single-bladed canoe paddles.

    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.
