速度の高速化なども図るように構成している。Four grass cutting blades (8) are provided on the same circumference around the rotating shaft (11) to form a plurality of rows of cuts for ventilation on the lawn vegetation surface. As shown in the figure, the turf cutting blade (8) forms the S-shaped bent cross-section of the tip blade (8a) within a certain thickness (T) to improve the strength of the blade (8a). At the same time, the resistance at the time of forming the cutting stitch is reduced to minimize the swelling of the soil at the cut end.
As is apparent from the above description, a turf cutting blade (8) for forming a cut for ventilation on a lawn vegetation surface is provided on the fuselage, and an auxiliary wheel (13) for supporting the fuselage is vertically adjustable in height. A lawn cutting machine configured to adjust the cutting depth by the grass cutting blade (8) by adjusting the vertical mounting height position of the auxiliary wheel (13). Thickness (T)
The cross section of the cutting edge (8a) of the turf cutting blade (8) is bent in an S shape. The cutting edge (8a) of the grass cutting blade (8) is bent into an S-shape to prevent the root and soil of the grass from sticking to the side of the grass cutting blade (8), thereby reducing the cutting resistance of the grass cutting blade (8). In addition to simplifying the drive structure of the grass cutting blade (8) and reducing the driving force, the blade tip (8a) is bent within the base thickness (T) of the grass cutting blade (8) to maintain strength. However, the thickness of the blade tip (8a) is made thinner to prevent the soil from rising at the cut end of the turf cutting blade (8), eliminating the need for pressure reduction by rollers, preventing turf from withering at the cut end, The structure is designed to simplify the structure and improve workability, and also to increase the speed of grass cutting work.
