摺動を妨げ切れ味が悪くなる欠点があった。2. Description of the Related Art The applicant has made efforts to develop and research a self-propelled mower that can surely mow even in a narrow place such as a ridge. We have applied for patents such as Japanese Patent No. 39222 and Japanese Patent Application Laid-Open No. 7-39225, and have produced a test machine and tested it. Especially, this type of mowing work is performed in a place with rough surface such as a ridge. Therefore, since the work is done while cutting the root of the grass together with the soil, the soil between the upper plate and the lower plate of the grass cutting blade is constantly filled with soil and cutting chips, and in some cases, they are the slide metal of the upper and lower grass cutting plates. There is a drawback that the cutting blade portions of the upper plate and the lower plate are fixed to the surface and the gap between them increases and the close sliding of the cutting blade portion is prevented, resulting in poor sharpness.

か困難な作業であった。In this case, the upper grass cutting plate and the lower grass cutting plate are disassembled to remove the mowing chips and the fixed mowing chips, and the upper grass cutting plate and the lower grass cutting plate are again held with proper tightening guide bolts to maintain proper clearance. The grass cutting work was continued with the tightening guide bolts attached, but the work of adjusting the grass cutting plates with the tightening guide bolts was performed by first tightening the upper and lower grass cutting plates with the tightening guide bolts, and then turning the tightening guide bolts in reverse. Although it was returned and the clearance was maintained by keeping a clearance gap between the upper and lower mowing blades, the tightening adjustment work by this nut was quite difficult for an amateur.

式草刈装置を提供するものである。According to the present invention, the leading and trailing edges of the upper and lower grass cutting plates are provided to reduce the sliding area of the upper and lower grass cutting blades, and the grass cutting chips that enter the sliding surface and try to adhere are immediately sheared and discharged backward. At the very least, it is possible to eliminate sticking of mowing shavings to the slide surface, and to keep the mowing upper plate and the upper mowing plate at a proper gap for performing the mowing operation. The upper blade is urged by the elastic force from the bottom to keep the blades of the upper and lower cutting blades in close contact with each other, and a concealment cover is provided to conceal the blade for supporting the blade and the lower blade. The height of the cutting edge is kept constant to keep the cutting height constant so that the cutting blade does not cut the soil as much as possible to increase the durability of the cutting blade and the grass is entangled with the mowing device. To prevent the above-mentioned drawbacks and to mow the side of the ridge. When cutting the grass, the right end of the mowing blade cuts the root of the grass with the soil under the surface of the water, so pay attention to the fact that the cutting blade part in this part is significantly worn. The present invention provides a hair clipper-type mowing device that is divided into the same divided blade plates, and the holder blades continuously connect the divided blade plates in a continuous state to partially replace the divided blade plates that are worn or have poor sharpness. Is.
