Abstract: A modular engine enclosure comprised of a hood and baffle is provided to channel cooling air along passages formed between their adjacent surfaces to the radiator of a water cooled engine. The passages provide acoustic air barriers and along with selected enclosure surfaces covered with sound absorbing foam, serve to contain engine sounds within the enclosure. The passages receive air from a generally upright inlet opening and direct it evenly over the top surface of the horizontally oriented radiator. After being drawn through the radiator, the air is exhausted generally horizontally out the back of the engine compartment. The modular construction of the enclosure allows it to be easily raised and/or removed so that maintenance and service activities can be performed on the engine and its components.

Abstract: A modular operator enclosure is provided for a wheeled vehicle such as a front mount mower or utility vehicle. The enclosure is provided with interconnected front and rear roll-bar structures which serve as a framework upon which a variety of enclosure elements can be attached. Selectively attachable to the framework are a roof element, a front windshield, rear and/or side windows and doors. Glass and metal or flexible windshields, windows and doors are available to meet differing use and weather needs. The module and its elements are quickly and easily assembled at the dealership, thereby enabling them to be shipped in a compact form. The module design provides the dealership and/or user with the option of initially equipping the enclosure with a minimum of elements and then later adding or changing the elements to thereby minimize cost and/or effort.

Abstract: A suspension for supporting an implement on a vehicle includes a transversely extending pivot shaft secured to a frame of the vehicle and a support link swingably mounted on the pivot shaft at one end portion. A second end portion of the support link extends therefrom in a fore-and-aft direction. Two spaced-apart, fore-and-aft extending support arms are also swingably secured to the pivot shaft at one end portion and are connected at another end portion to opposite sides of the implement. A lift member is coupled to the frame of the vehicle at a first end portion and to the support link at a second end portion for swinging the link about the pivot shaft. A lost motion coupling is provided between a midportion of each of the two support arms and the second end portion of the support link. The lost motion coupling includes a pin and an oversized sleeve for receiving the pin.
