    摘要: A rotating rate control apparatus for adjusting rotation of an engine of a working vehicle between a minimum rate and a maximum rate. The control apparatus has a first, a second and a third rotating rate adjusting devices. The first rotating rate adjusting device adjusts a basic rotating rate of the engine between the minimum rate and maximum rate. The second rotating rate adjusting device is shiftable between an ON position and an OFF position. The second rotating rate adjusting device is operable, when in the ON position, to set the engine to a predetermined rotating rate between the minimum rate and the maximum rate inclusive. The third rotating rate adjusting device is operable, when the second rotating rate adjusting device is in the OFF position, to adjust the rotating rate of the engine between the basic rotating rate adjusted by the first rotating rate adjusting device and the maximum rate.

    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 comprising a cutting unit disposed between front and rear wheels, a grass discharge duct extending rearwardly from the cutting unit, and a grass collecting container defining a top opening for receiving grass clippings sent through the discharge duct. The grass collecting container includes a mouthpiece extending along peripheries of the top opening to rest on a U-shaped support frame mounted at a rear end of the mower. The mouthpiece is connected to the support frame by a projection and bore engagement. The support frame includes a holder defining an upwardly opening recess, and the container has a cover defining a downwardly opening recess at a position opposed to the holder. The two recesses define an opening for receiving a rear end of the grass discharge duct. The grass discharge duct includes an annular engagement portion extending peripherally of the rear end thereof for engagement with inner edges of the two recesses.

    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.
