PROBLEM TO BE SOLVED: To provide a mower enabling wheels, a transmission shaft, a rotary blade, a rotation-amplifying mechanism and a holder to be disassembled together, and having a simple structure.SOLUTION: The mower is equipped with a body 11, the wheels, a main shaft 13 for a tilling tine of a tiller, and connected to the body 11, a motor 115 for rotating the main shaft 13 at a rotating speed for tilling, and installed in the body 11, the rotary blade 18 for the mowing, arranged at the front side of the main shaft 13, constituted so as to have a width substantially equal to the main shaft 13, and rotatably driven around a horizontal shaft as the center, the rotation-amplifying mechanism 30 installed at least in either of the right or left side of the main shaft 13, and rotatably driving the rotary blade shaft of the rotary blade 18 by amplifying the rotation of the main shaft 13, the transmission shaft 29 installed in the terminal parts at right and left both sides of the main shaft 13, and for transmitting the rotation of the main shaft 13 to the rotation-amplifying mechanism, pins 31 and 32 for detachably connecting the transmission shaft 29 with the main shaft 13, and the holder for supporting the wheels, the transmission shaft 29 and the rotary blade shaft, and holding the rotation-amplifying mechanism 30. The mower is constituted so that the wheels, the transmission shaft, the rotary blade, the rotation-amplifying mechanism and the holder may be disassembled together by removing the transmission shaft 29 from the main shaft 13.COPYRIGHT: (C)2012,JPO&INPIT【課題】構成が簡易な草刈機を提供すること。【解決手段】本体11と、車輪と、耕耘機の耕耘爪用の、本体11に連結された主軸13と、主軸13を耕耘用の回転速度で回転させる、本体11に設けられたモータ115と、主軸13の前方に配置され、主軸13と実質上同じ幅に構成され、横軸芯に回転駆動する草刈用の回転刃18と、主軸13の少なくとも左右いずれかの側方に設けられており、主軸13の回転を増幅して、回転刃18の回転刃軸を回転駆動させる回転増幅機構30と、主軸13の左右両側の端部分に設けられ、主軸13の回転を回転増幅機構に伝動するための伝動軸29と、伝動軸29と主軸13を着脱可能に連結するピン31、32と、車輪、伝動軸29、回転刃軸を支持し、回転増幅機構30を保持する保持体とを備え、伝動軸29を13主軸から外すことによって、車輪、伝動軸、回転刃、回転増幅機構、及び保持体が一体となって外れる、草刈機である。【選択図】図1
