摘要： A lawn mower includes a blade housing enclosing grass cutting blades and having a lateral discharge opening, a blower unit connected to the discharge opening, and a duct connected to the blower unit for transporting grass clippings to a grass catcher. The blower unit includes an elbow-like lower blower housing connected to the blade housing, an upper blower housing having a substantially vertical cylindrical side wall connected to the duct, and an impeller mounted in the upper blower housing to be rotatable about a vertical axis. The impeller has a plane of rotation above a plane of rotation of the blades. The lower blower housing includes a flange for connection to the upper blower housing. The flange has an opening elongated in a direction along a passage defined by the two blower housings. This opening has width approximately half of the diameter of the impeller.

摘要： A mower unit of grass cutting machine has at least two blades. The left blade is rotatable clockwise, while the right blade is rotatable counterclockwise. A grass discharge passage is formed between the two blades. An endless rotational belt for transmitting drive to the two blades is offset forwardly in a region between the blades, thereby forming, between the blades, a space without the endless rotational belt. The grass discharge passage has an upper surface inclined rearwardly and upwardly to extend from a position forwardly of a pair of pulleys corresponding to the two blades.

摘要： An engine speed control system for a working vehicle having an engine, and a propelling transmission and a power takeoff device driven by the engine. Engine speed is adjustable by an accelerator controlled by control signals outputted from a control unit. The control unit is connected to a clutch operation detecting switch for detecting an operative state of a power takeoff clutch for operating a power takeoff device and to a shift condition detecting switch for detecting a shift of the propelling transmission. The control unit outputs a control signal for rotating the engine at an idling speed when the propelling transmission is in neutral and the power takeoff clutch is disengaged, and a control signal for rotating the engine at a high rotating rate when the propelling transmission is in a drive transmitting position or the power takeoff clutch is engaged.

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.

摘要： A working vehicle comprising an engine mounted on a vehicle frame, a control box mounted on the vehicle frame, and a radiator erected on the vehicle frame between the engine and the control box structure. A dust-proof space is defined by the control box, the radiator and a hinged hood covering the engine. Elastic sealing elements are arranged between opposite lateral sides of the control box and the radiator, and between an upper end of the radiator and the hood. The hood in a closed position presses upon the upper elastic elements to provide an additional support for the radiator and to seal the dust-proof space.
