歩行型芝刈機に適するような比較的狭い面積での芝刈り
作業での操縦者の労力軽減を図ることを目的とする。The walking lawn mower has a small size, so that it can work even in a narrow place such as a grove, and has good handleability for easy storage in a warehouse or the like. Although it is for the area for lawn mowing, it is disadvantageous in terms of labor since the pilot always walks during the lawn mowing operation. Therefore, there was a view that it was difficult to use for elderly people and for those who could not walk. Accordingly, the present invention realizes a small riding lawn mower having a good handling property comparable to that of a walking lawn mower, and enables a pilot to perform lawn mowing work in a relatively small area suitable for a conventional walking lawn mower. The purpose of this is to reduce the labor.

用芝刈機を構成したものである。SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, a mower is arranged between front and rear wheels, a driver's seat is arranged above the mower, and a vertical axis type is provided. The engine with the crankshaft facing downward is disposed between the pair of left and right rear wheels in a horizontal position in which the cylinder is located on the lateral side of the crankshaft. A small riding lawn mower is constituted by a body layout characterized by being arranged in an overlapping state, and having a carburetor at a front side of a cylinder and a muffler at a rear side.

る。According to the layout having the above-mentioned characteristic configuration, an engine which is disposed between the left and right rear wheels in forming a small lawn mower having a mower disposed between the front and rear wheels will be described in detail in the embodiment. The driver's seat on the mower located closer to the front than the one with the cylinder facing forward is slightly rearward, that is, the driver on board is placed in the center of the front and rear wheels as much as possible. Can be contributed.

にも寄与する。[0006] Since the muffler is arranged on the rear side of the cylinder to keep the heated object as far away from the control unit as possible, the driver's seat can be brought closer to the engine. Can be contributed. In addition, since the muffler is located at the rear of the fuselage, it is easy to lay out the muffler alone.
In addition, since the carburetor is disposed on the front side of the cylinder where the heat effect of the muffler is unlikely to occur, it contributes to stabilizing the vaporization performance.

とともに、質量の集中化を図ることも可能になる。Further, since the crankshaft is directed downward, the length of the transmission structure such as belts and gears can be reduced as compared with the case where the crankshaft is directed upward, and the transmission system can be made compact. In addition, since the engine and the rear wheel are arranged in a state of overlapping in the front-rear direction, the transmission portion from the engine to the rear axle can also be arranged near the rear wheel, and the entire rear wheel drive structure including the engine is provided. In addition to being compact, it is also possible to concentrate the mass.

理的な小型乗用芝刈機を提供できた。Therefore, with the rational layout of the mid-mount lawn mower, the driver's seating position can be positioned as much as possible in the center between the front and rear wheels so that light maneuverability can be obtained. While keeping the wheel transmission structure compact,
A rational small-sized riding lawn mower with good handleability that can exhibit the engine performance stably was provided.
