摘要： An engine enclosure for use on a vehicle having a cooling system for a vertical shaft type engine with a cooling air intake fan disposed above the engine. The engine enclosure comprises an upper hood for covering the engine from above, the upper hood having an upper surface and right and left side surfaces extending downward from the upper surface, a lower hood for covering lateral areas of the engine, and a cooling air intake opening formed in a position above a lower end of at least one of the right and left side surfaces of the upper hood for taking in ambient air. A partition wall member is disposed between the cooling air intake opening and the cooling air intake fan for restricting mixing of ambient air drawn by the fan and heat generating from the engine.

摘要： A transmission for an agricultural working vehicle is provided which includes a gear type forward speed changing mechanism and a wrapping connector backward driving mechanism selectively operable to connect an input shaft and an output shaft. The input shaft carries a plurality of change speed gears and a driving sprocket fixed thereto. The output shaft carries a driven sprocket relatively rotatably mounted thereon and operatively connected to the driving sprocket by a wrapping connector, and a shift gear slidably splined thereto and including gear portions selectively engageable with the change speed gears. The shift gear is linked to the driven sprocket by an engagement mechanism to provide a backward drive state when shift gear assumes a position other than change speed positions.

摘要： A lawn mower comprises a vehicle body, a cutting unit mounted below the vehicle body, a grass catcher mounted rearwardly of the vehicle body, and a discharge duct extending between the cutting unit and the catcher for transmitting grass clippings from the cutting unit to the catcher. The catcher defines an opening at which a lid member is removably mounted, the lid member includes a coupler opening for coupling to a discharge opening of the discharge duct and an air vent around the coupler opening. The catcher is switchable between a sideways turned posture in which the coupler opening is coupled to the discharge opening and an upright posture in which the coupler opening is directed upwardly.
