  • Patent number: 4731983
    Abstract: 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.

  • Patent number: 4727768
    Abstract: 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.

  • Patent number: 4721494
    Abstract: A drive transmission structure for a tractor comprising a belt drive system for transmitting power from an engine output shaft to a transmission having a brake mechanism. The belt drive system includes a belt type stepless change speed mechanism having a split pulley assembly and a swing device for swinging the split pulley assembly toward the engine output shaft and the transmission, a first belt for transmitting the power from the engine output shaft to the split pulley assembly, and a second belt for transmitting the power from the split pulley assembly to the transmission. The pulley assembly defines two split pulley sections for engaging the first and second belts, respectively. A control device is provided to change power transmission ratios by actuating the swing device. Further, a tension pulley type clutch mechanism is provided to act on the first belt or the second belt. The brake mechanism and the tension pulley type clutch mechanism are controlled by the clutch and brake control mechanism.
