本考案は、リール式芝刈りカツタ及び車輪を駆
動するエンジンを設けた歩行型芝刈機に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a walk-behind lawn mower equipped with a reel-type lawn mower and an engine that drives the wheels.

In the above-mentioned walk-behind lawn mower, conventionally, as disclosed in Utility Model Application No. 1461/1983, the reel-type cutter is disposed at an intermediate position between the front wheels and the rear wheels, and the reel Some types of cutters have a rotating shaft that projects outward, and a rotary blade that rotates around a horizontal axis is detachably attached to the projecting shaft.

行えるよう構成したものである。
In the above conventional structure, when the rotary blade is not attached, the reel blade performs normal lawn mowing work, and when the rotary blade is attached and rotated, it can be used, for example, to cut the lawn or cut the edge of the lawn. When mowing grass that is growing on top of partition blocks, stones, etc., the rotary blade that rotates around the horizontal axis can be used to cut the grass as described above. The structure is such that the lawn can be cut effectively.

えない欠点があつた。 However, in the above-mentioned conventional structure, the rotary blade is provided at an intermediate position between the front and rear wheels, so that, for example, during the edge-mowing work, edge-mowing is performed along the partition on one side of the lawn and the corner is cut. When the front wheel reached the point where it came into contact with the other partition, it could only work up to the point where the front wheels came into contact with the other partition, making it impossible to perform effective edge cutting near the corner.

労力を要する欠点もあつた。 In addition, when traveling with the rotary blade attached, in order to raise the rotary blade above the ground, in the conventional structure described above, it is necessary to lift the handle and maintain a state where only the front wheels are in contact with the ground. It is very difficult to walk forward, and
There were also drawbacks that required effort.
本考案は、合理的配置構造により、上記不具合

The characteristic configuration of the present invention is a walking lawn mower equipped with a reel-type lawn mowing cutter, front wheels and rear wheels, and an engine that drives the rear wheels.
The drive rotation shaft of the cutter is arranged in front of the front wheel, and the drive rotation shaft is equipped with a mounting part that connects the rotary lawn cutting blade to the outside of the front wheel in a manner that allows it to rotate integrally and to be detachably attached. In addition, the lawn cutting rotary blade is arranged such that its front end is located further forward of the machine body than the front end of the cover that covers the cutter, and its lower end is lower than the ground contact part of each of the wheels. Its functions and effects are as follows.
前記回転刃を取付けた状態で際刈り作業を行う
と、芝生の一辺の端縁に沿つて際切り作業を行
い、角部まで到つた場合であつても、回転刃は前
車輪および機体最前端の双方よりも前方位置で、

有効に行える。
If you cut edges with the rotary blade attached, the cutting will be carried out along the edge of one side of the lawn, and even if it reaches the corner, the rotary blade will cut the front wheels and the very front edge of the machine. in a position anterior to both of the
Moreover, since it is located laterally outward from the cutter and the front wheels, it can be approached to a position where it almost touches the partition on the front side of the machine body, making it possible to effectively cut edges at corners.
また、後輪を駆動する構成により、回転刃を装

る。 In addition, due to the configuration in which the rear wheels are driven, in order to move around with the rotary blade attached, the handle must be pushed down to maintain the state in which the rotary blade is floating above the ground. This method is more effective in terms of effort, operability, and maneuverability than conventional lifting methods.
従つて、本考案によれば、リール式カツタの駆

Therefore, according to the present invention, it is possible to effectively utilize the drive shaft of a reel-type cutter to perform edge mowing work without complicating the structure significantly, and yet We have now been able to provide a cutter that can be efficiently mowed without leaving any mowing left behind, and that has as good operability as possible when moving and traveling when a rotary blade is attached.
