To provide a mower with which a mowing cord can be kept in an appropriate protruding state, in a mower in which a mowing cord 11 of resin is wound on a rotating body 1, the rotating body 1 is provided with a winding member 3 on which the mowing cord 11 is wound, the winding member 3 has a first peripheral concave groove 38 and a second peripheral concave groove 39 on which the mowing cord 11 is wound, and a winding portion 11d of the mowing cord 11 is wound as to be aligned from an inner side in a diameter direction to an outer side within each of the first peripheral concave groove 38 and the second peripheral concave groove 39.

There is provided a grass cutter in which a cord can be easily replaced by a user and the length of the cord can be easily adjusted. The rotor section of the grass cutter has an upper cover, a lower cover and cord reels provided in an internal space formed by the upper cover and the lower cover. The cord reels are wound with two separate nylon cords. The length of the nylon cords drawn from the cord reels are adjusted by the cord adjustment mechanisms provided on the upper cover.

The invention relates to a trimmer head comprising: a body to be coupled to a driving shaft of a vegetation cutting machine for rotating about a rotation axis, at least one rod comprising at least one retaining portion for holding a cutting filament in a determined direction, wherein the body comprises a housing for receiving each end of the rod such that the rod axis is perpendicular to the rotation axis of the body and substantially tangential to the rotational path of the body, the housing and the rod ends having respective shapes allowing at least two relative orientations of the rod relative to the body: a first orientation wherein the determined direction is substantially parallel to the rotation axis of the body, and a second orientation wherein the determined direction is substantially radial and substantially perpendicular to the rotation axis of the body.

A monofilament for mowing characterized by being produced by spinning a resin composition, said resin composition comprising 70-97 parts by weight of a polylactic acid resin (A) and 30-3 parts by weight of an adipate plasticizer (B), each relative to 100 parts by weight of the sum of the polylactic acid resin (A) and the adipate plasticizer (B). Thus, the monofilament for mowing, which is biodegradable, shows an excellent mowing performance and has a high breakage resistance and high abrasion resistance, is provided.

A trimmer line spool has first and second spool chambers for a trimmer line. First and second holder pairs are provided. The first holder pair has first and second trimmer line holders associated with the first spool chamber and the second spool chamber, respectively. The second holder pair has first and second trimmer line holders associated with the first spool chamber and the second spool chamber, respectively. The trimmer line holders of the first holder pair each have a first opening for the trimmer line. The trimmer line holders of the second holder pair each have a second opening for the trimmer line. A diameter of the first openings is larger than a diameter of the second openings. The first openings are positioned at an angle of 150 to 210 to each other. The second openings are positioned at an angle of 150 to 210 to each other.

A trimmer and a trimmer head include an upper cover assembly being connected to and driven by a motor, wherein the upper cover assembly is configured to be removably connected to at least one of a first trimming assembly or a second trimming assembly selectively, and is provided with at least one connection hole in its side wall; the first trimming assembly is configured to include a first lower cover, a first cutting member, and a first base; the second trimming assembly is configured to include a second lower cover, a second cutting member, and a second base; wherein the first base is at least partially inserted into the connection hole when the first trimming assembly is mounted, and the second lower cover is at least partially inserted into the connection hole when the second trimming assembly is mounted.

A trimmer head includes a housing rotatable about a rotational axis. The housing includes a main body defining a cavity, and a cap removably coupled to the main body. The trimmer head additionally includes a spool supported in the cavity and operable to support line to be dispensed, a retainer positioned between the housing and the spool. and a first ring protruding from a distal end of the housing.

An elongated line device that includes an elongated core and a sheath surrounding and connected to the elongated core. The elongated core includes a polymer selected from the group consisting of a high molecular weight strain hardened polymeric matrix, a cellulose-derived fiber matrix and mixtures thereof. The sheath includes an amorphous polymeric matrix comprising cellulous ester and at least one plasticizer.

A novel monofilament trimmer line is provided for reducing noise, reducing air drag and increasing durability by having a non-round cross-sectional shape defined as a polygon with three to six sides wherein the vertices between adjacent sides have been replaced with generous circular arcs, the arcs of a parabola, or even other arc shapes so long as the arc is convex and contains no sharp edges and wherein each arc is tangent to the two adjacent sides with a smooth and continuous transition, and the sides of the polygon are either straight or slightly convex, but not concave.
