Abstract

[PROBLEMS] To easily work in a narrow place, a place where a lot of trees are planted, garden stones, concrete fences, telephone poles and gate poles.
A mounting hole to be attached to a mower is formed in the center of a steel disk having a diameter of 100 mm and a thickness of 1 mm, and an iron piece and a wire handling member having a height of 30 mm and a width of 20 mm are welded to the left and right of the disk. A wire attachment hole is made at the center point of this member. A metal wire with vinyl coating is cut to 200 mm. Make a knot at the end of the wire. Left and right iron pieces of the disk. A knot is made near the outside through the hole of the wire attachment member from the inside. By rotating a soft blade using a metal wire with vinyl clothing, you can work safely without damaging the plant. By attaching a cylinder with a diameter of 80 mm and a height of 20 mm under the blade, the wire prevents contact with the ground and prevents scattering of pebbles and the like.

Description

The present invention is an improvement of a blade that uses a metal wire of vinyl clothing for the blade of a power mower.

The blades of power mowers are made of steel and are suitable for work in a wide area, but when used in narrow spaces, planted trees or on side of garden stones or concrete fences, etc. In such a place, a steel blade mower cannot be used in such a place, and the device disclosed in Japanese Patent Publication No. 2006-166890 has no idea of preventing the scattering of pebbles etc. is there. Even if it is easy to replace the nylon thread, it is not easy to replace it with a conventional steel blade.

When using a steel blade mower on the side of a garden plant or hedge, the tree may be damaged or cut, and when used on the side of a garden stone, concrete fence or utility pole, This will damage not only the blade of the mower but also the mower.

In the first aspect of the present invention, an attachment hole for attaching to a mower is formed in the center of a steel disc having a diameter of 100 mm and a thickness of 1 mm, and an iron piece and a wire attachment member having a height of 30 mm and a width of 20 mm are welded to the left and right sides of the disc. A hole for wire attachment is made at the center point of the iron piece and wire attachment member. Cut a vinyl-coated metal wire to 200 mm. Make a knot at the end of the metal wire of the vinyl clothing, make a knot from the inside through the hole on the left and right iron pieces of the disk, the wire attachment member, near the outside of the member. (Prevents detachment from the wire member)
The blade of the power mower is replaced with the metal wire blade of the vinyl clothing of the above device. The mounting hole of the steel blade is the same as the mounting hole of the metal wire blade of the vinyl clothing. The metal wire of the vinyl clothing can cut the grass and damage the blades of trees and mowers. Work safely without incident.

In the second aspect of the present invention, a cylinder having a diameter of 80 mm and a height of 20 mm is welded to the lower side of the disk of the first aspect.
When the wire attached to the disk rotates, the wire prevents contact with the ground and prevents scattering of pebbles.

The blades can be easily replaced because the mounting size is the same as the steel blades of power mowers. The grass can be cut to the root of the tree, and there is no damage to the tree and it is safe. You can also cut root grass such as garden stones, concrete fences, telephone poles, and gate poles. Work can be done safely without damaging the garden stones and concrete products, and without damage to the mower and blade.
Scattering of pebbles and the like can be prevented by attaching a cylinder to the lower side of the blade.
