摘要： A plant cutter apparatus has a one-piece handling rod having an outer pipe portion, an inner pipe portion disposed concentrically within the outer pipe portion, and first, second and third radial stay portions extending between and interconnecting the outer pipe portion and the inner pipe portion. The first, second and third radial stay portions are arranged at non-equal angular intervals such that an angle &thgr;1 formed between the first and second stay portions, an angle &thgr;2 formed between the second and third stay portions, and an angle &thgr;3 formed between the third and first stay portions differ from each other. A drive shaft extends through the inner pipe portion and is rotatably supported within the inner pipe portion via a bushing disposed between the drive shaft and the inner pipe portion. A drive source unit is mounted at one end of the handling rod for rotating the drive shaft. A cutter blade is mounted at another end of the handling rod and is connected to the drive shaft for rotation therewith.

摘要： Drive shaft of a plant cutter apparatus includes an elongate main shaft portion made of a titanium alloy, and end shaft portions made of steel and integrally joined to the opposite ends of the main shaft portion. The titanium alloy has substantially the same mechanical strengths as the steel. Therefore, the titanium-alloy-made main shaft portion can secure rigidity that is normally required of the plant cutter's drive shaft, and can also reduce the weight of the drive shaft to thereby minimize unwanted sagging-induced vibrations of the drive shaft caused by the shaft's own weight.

摘要： A walk-behind working machine includes a first clutch mechanism for connecting or disconnecting drive between an engine and a working member of the working machine. The first clutch mechanism includes a first clutch lever having a first activating member. A second clutch mechanism is configured to connect or disconnect drive between the engine and traveling members of the working machine. The second clutch mechanism includes a second clutch lever having a second activating member. A throttle regulating mechanism has a pivoting member for engagement with one of the first activating member of the first clutch mechanism and the second activating member of the second clutch mechanism so as to undergo pivotal movement to shift a throttle for the engine from a first opened position in which an idling engine speed is produced to a second opened position in which a working-machine-activating engine speed is produced.

摘要： A bush cutting machine with a tubular operating pole connected to an outlet of an exhaust muffler and doubling as an exhaust passage is provided. Exhaust gases discharged from an engine flow from the exhaust muffler through the operating pole and are then discharged into the air. The substantial capacity of the exhaust muffler is increased by the operating pole, and the exhaust noise of the engine is reduced.

摘要： A handle holder for mounting a U-shaped handle to an operating pole of a bush cutting machine. The handle holder has a first holding member and a second holding member. The first holding member has an operating pole insertion hole for insertion of the operating pole therethrough, an oblique groove, and a handle receiving groove for receiving the base of the handle. The second holding member has a wedge and a handle retaining groove. The wedge is fitted into the groove of the first holding member to fix the first holding member to the operating pole. The handle is interposed and held between the handle receiving groove of the first holding member and the handle retaining groove of the second holding member to be fixed to the first holding member.

摘要： A walk-behind working machine includes a first clutch lever, a second clutch lever, and a throttle having a degree of opening controllable by each of the first clutch lever and the second clutch lever. The working machine also includes a pivoting member, a throttle wire connected to the pivoting member, and a first activating member provided to the first clutch lever for engagement with an engagement member provided to the pivoting member. When the first clutch lever is operated to place a first clutch in a connected state, the throttle is shifted by operation of the first clutch lever from a first opened position in which an idling engine speed is produced to a second opened position in which a working-machine-activating engine speed is produced.
