摘要： A working machine has an operation switching lever mounted on a handle in the vicinity of a handle grip and is arranged to be manipulated by one of the hands of the operator to transmit or interrupt a driving force outputted from the drive source to the working tool. A drive switching lever is mounted on the handle and is arranged to be manipulated by one of the hands of the operator to operate a continuously variable transmission to switch driving wheels from a halt condition to a high-speed advancement condition. A disc is mounted on the handle for undergoing rotational movement relative to the drive switching lever. A control member positions the disc at a preselected angular position relative to the drive switching lever to regulate an amount of pivotal movement of the drive switching lever for adjusting a rotational speed of the driving wheels.

摘要： A lawn mower comprises a power source for rotatably driving an output shaft, a housing having an interior space having a generally spiral-shaped portion, and a cutting blade disposed in the interior space of the housing and connected to the output shaft for rotation therewith to cut grass. The rotating cutting blade coacts with the spiral-shaped portion of the interior space to generate a swirling air flow that causes the cut grass to swirl within the interior space. A grass discharge passage communicates with the interior space of the housing and discharges therethrough grass cut by the cutting blade and swirling within the interior space of the housing. A pivotal shutter is pivoted about a generally vertical axis by manual operation of a control member to open and close the grass discharge passage. The pivotal shutter comprises a pivotal shaft and a unitary shutter member mounted on the pivotal shaft to undergo pivotal movement therewith for opening and closing the grass discharge passage.

摘要： A walk behind working machine has a frame having a forward end portion and a rear end portion, a prime mover mounted on the frame, a pair of drive wheels mounted on the frame for undergoing rotation, and a power transmission mechanism for transmitting rotational power from the prime mover to the drive wheels. A running clutch is adapted to be placed in an engaged state in which rotational power is transmitted to the drive wheels and in a disengaged state in which rotational power is not transmitted to the drive wheels. A pair of operating handles extend from the rear end portion of the frame. A single grip/clutch lever serves as a grip handle for being gripped by an operator to maneuver the working machine and as a clutch lever manually operable to selectively place the running clutch in the engaged state and the disengaged state. The grip/clutch lever is pivotally mounted on distal end portions of the operating handles to undergo pivotal movement in forward and rearward directions of the frame between a rearward stop position having a first forward tilt and in which the running clutch is in the disengaged state and a forward operating position having a second forward position greater than the first forward position and in which the running clutch is in the engaged state.

摘要： A cutter blade for lawn mowers having an airlift curved from a cutting edge formed on a rotationally leading edge toward a rotationally trailing edge. The trailing edge of the airlift is shaped in a waveform comprising a plurality of protrusions and a plurality of depressions. The protrusion closest to an outer end where the centrifugal force is greatest during the rotation of the cutter blade, is greatest in width so as to improve the discharging capability of grass clippings. The depressions limit negative pressure generated rotationally behind the airlift. A plurality of vent holes formed in the airlift is arranged radially in lines.

摘要： A lawn mower includes a mower body and a grass bag provided at the rear of the mower body. The mower body has a cutter deck rotatably accommodating a cutter blade, a carrying passage for guiding grass clippings into the grass bag, and an air return passage for guiding only air from the grass bag into the cutter deck. Cutter deck-facing openings of the air return passage are opened in line with the rotating track of airlifts provided at the opposite ends of the cutter blade. A swirling airflow inside the cutter deck induced by the rotation of the cutter blade is in the same direction as that of air returned via the air return passage, resulting in a smooth airflow inside the cutter deck.

摘要： Switch operation mechanism includes a handling lever pivotally connected to a portion of a handle, a generally-fan-shaped actuating member pivotally connected at its pivot portion to the handle in such a manner that the actuating member is pivotable in response to operation, by a human operator, of the handling lever, and a noncontact reed switch for turning on or off a cutter-driving electric motor in accordance with an ON/OFF state of the noncontact reed switch. The ON/OFF state of the noncontact reed switch is determined in accordance with pivoting movement, toward or away from the switch, of the actuating member responsive to the operation of the handling lever. With such arrangements, the switching operations of the operation mechanism can be performed accurately in a stable manner.
