定すれば草刈中を広くすることが出来るからそれだけ能
率良く草刈作業を行うことが出来る。In the present invention, a second mowing blade is provided outside the first mowing blade and rotates in conjunction with the second mowing blade, and the cutting angle of the second mowing blade can be freely adjusted. If you fix it, you can widen the mowing area, which makes mowing work more efficient.
更に第２草刈刃を畦側面の傾斜に合わせて固定すれば畦
上の直進走行で畦上面別と畦斜面刈とを町
同時に行うことが出来る駅用草刈機となる。Furthermore, by fixing the second mowing blade in accordance with the inclination of the ridge side surface, the mower for the station can mowing the ridge top surface and the ridge slope at the same time by running straight on the ridge.

ことになる。In this way, it has become an extremely efficient ridge weed mower that can simultaneously cut the grass growing on the ridge top surface and the ridge slope, which was considered difficult to do in the past, without having to sweep it sideways. Since the feet of the person are always ζ2 apart, there is no danger (
2. The operation is extremely simple and requires no effort, as the operator only needs to hold the control handle and follow the self-propelled aircraft.

性の秀れた駅用草刈機を提供することになる。In the conventional case, the angle adjustment of this second mowing blade was performed one by one.
It was inconvenient to have to go to the mowing blade and adjust it, and the workability was that much lower, but the present invention solves this second problem.
The operating mechanism that rotates and fixes the mowing blade at a predetermined angle is split into two parts on the control handle C, so you can continue working on the spot without having to go to the second mowing blade each time, resulting in excellent workability. We will provide grass mowers for stations.
