Abstract

PURPOSE:To perform easy and neat mowing of weeds on levee by attaching a swinging apparatus to the attaching base of a holding arm for holding a grass-mowing disk blade to enable the reciprocative motion of the disk blade in lateral direction and making the attaching position of the holding arm to be changeable in lateral direction of the machine body. CONSTITUTION:A holding arm 4 is protruded in front of a grass-mowing machine body 2 furnished with a wheel 1 and a grass-mowing disk blade 3 is attached to the tip end of the holding arm 4. A swinging apparatus 5 to swing the tip end of the holding arm 4 in lateral direction is attached to the attaching base part 4' of the holding arm 4 to enable the reciprocative motion of the grass-mowing disk blade 3 in lateral direction in front of the machine body. When the grass-mowing disk blade 3 is rotated counterclockwise, mowing of grass is performed by attaching the holding arm 4 to the right side of the machine body relative to the moving direction of the body. When the rotation is clockwise, the holding arm 4 is attached to the left side of the machine body. Even weeds on a narrow levee can be neatly mowed by the mower.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lawn mower that can also cut grass on ridges.

[Conventional technology and inventions will solve the problem] Issues to be addressed]

Conventional mowers have a mowing blade located at the front of the machine that rotates at high speed to cut weeds.

When mowing weeds on narrow ridges, this method has the disadvantage that, although it is possible to mow the weeds in the center, it is difficult to mow the weeds at both the left and right ends.

The present invention provides a mower that can also mow grass on ridges, which solves these drawbacks.

[Means to solve the problem]

The present invention will now be described in detail with reference to the accompanying drawings.

A holding arm 4 is provided protrudingly in front of a mower body 2 equipped with wheels l,
In this mower in which the mowing blade plate 3 is provided at the tip of the holding arm 4, a swing device 5 for swinging the tip of the holding arm 4 from side to side is provided at the mounting base 4° of the holding arm 4, and the mowing blade plate 3 is provided at the mounting base 4° of the holding arm 4. is provided at the front of the machine so that it can reciprocate left and right, and the mounting position of this holding arm 4 is located on the right side of the machine with respect to the forward direction when the mowing blade plate 3 rotates counterclockwise, and vice versa. This invention relates to a grass mower that is capable of mowing grass on ridges and is characterized in that it is positioned on the left side of the machine body when the machine rotates clockwise.

[For production]

A case where the mowing blade plate 3 rotates counterclockwise will be explained.

The holding arm 4 is attached to the right side with respect to the forward direction of the mower body 2, and the swinging device 5 swings the mower blade plate 3 left and right, so that when the mower body 2 runs on a ridge, the mower blade plate 3 is It is located protruding from the right end of the ridge, and moves back and forth from that position to the left, so weeds on relatively intermediate ridges can be neatly swept away in one mowing.

If the ridge width is a little wider, adjust the stroke of this reciprocating surface to a smaller value and move forward while sweeping away weeds from the right side to the center of the left side, then turn around and return to the left side to sweep away the weeds in the uncut area on the opposite side. If you sweep it in the same direction toward the center, you will be able to cleanly sweep and reap the weeds on a relatively wide ridge by mowing twice.

The rotary shaft 31 in the holding arm 4 is rotated through the bevel mechanism, and the rotation of the rotary shaft 31 is caused to rotate the mowing blade plate 3 at high speed through the bevel mechanism.

〔Effect of the invention〕

Since the present invention is constructed as described above, it has excellent practicality in that the weeds on the ridge can be thoroughly and neatly mowed by the swinging motion of the holding arm and the left and right reciprocating movement of the mowing blade plate provided at the tip. This mower can also cut grass on ridges.
