Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bogie for mowing a mowing machine while moving the mowing machine, a mowing method using such a bogie for mowing, and a use for such a bogie for mowing machines. Related to mowing machines.

[0002]

Conventionally, a mowing machine 1 as shown in FIG. 14 has been used to cut grass growing on a bank of a field or the like. The mower 1 is configured so that the blade 4 can be rotated by a gasoline engine (drive means) 2 to cut the grass. This mower 1
Starts the gasoline engine 2, puts the band 5 on the shoulder of the worker, and holds the grip 6 and the gripping portion 7 by hands to be held in the air. Next, the cutting blade 4 is rotated at a high speed by increasing the rotation speed of the drive device 2, and the grass is cut by swinging the cutting blade 4 that rotates at a high speed substantially parallel to the ground.

[0003] However, the mower 1 is a gasoline engine 2
Therefore, the grip 6 and the grip 7 attached to the operating rod 3 of the mower 1 must be gripped with a strong force. For this reason, mowing work by the mowing machine 1 is very hard work, and persons without physical strength, such as the elderly and women, cannot be used. When the rotating cutting blade 4 hits a stone or the like on the ground, a reaction force acts on the cutting blade 4 from the stone, so that the tip of the operating rod 3 to which the cutting blade 4 is attached is shaken. There was sometimes. For this reason, the rotating blade 4
May hit the worker, and mowing with the mower 1 was a difficult task.

Accordingly, the present inventor has devised a bogie for a mower that can easily and safely perform mowing work by mounting a mower, and filed a patent application on May 7, 1993 (see Japanese Patent Application No. No. 5-131120).

[0005] However, even with this mower bogie, when the handle is swung by hand, hand fatigue is involved, so that it was necessary to make mowing easier. Further, when the mowing machine is rocked by using the driving means, it is necessary to be able to more efficiently mow the mowing machine because a large amount of fuel is consumed for the driving means. Then, the present inventor conducted further intensive studies in order to solve such a problem, and as a result, came to the present invention.

[0006]

The gist of the mowing bogie according to the present invention is to mount a mowing machine provided with a mowing blade at its tip end which is driven to rotate by driving means. A mowing bogie for mowing the ground by moving the mower toward the tip while reciprocatingly swinging about a predetermined rotation axis substantially parallel to the ground. By rotating and driving the cutting blade in a certain rotation direction, the mowing machine can be provided with a forward or backward force about the rotation axis in the same direction as the certain rotation direction.

[0007] That is, the present invention is a basic invention that converts the rotational force of a cutting blade into a swinging force, and uses a rotating force of a cutting blade to swing a mower and cut a grass. It is an invention which widely includes a trolley. In addition, the shape of the cutting blade is not limited to the disk shape, and may be a cross shape, a disk having wires arranged around the disk, or the like.

[0008] The mower bogie of the present invention drives the mowing blade, which is substantially parallel to the ground, to rotate in a constant rotational direction, so that the mower can rotate itself around the rotation axis in the constant rotational direction. In the same direction. As a principle, it is conceivable that a predetermined portion around the rotating cutting blade is brought into contact with the ground, and the mower itself swings by a reaction force from the ground to the predetermined portion and the like around the blade. For example,
It is conceivable that the vicinity of the rear end of the rotating blade is brought into contact with the ground, and the mower itself swings by a reaction force from the ground against the vicinity of the rear end. That is, it is conceivable that the mowing machine itself swings while the cutting blade rolls on the ground due to the rotational force of the cutting blade. Note that the cutting blade may not roll completely on the ground, but may roll while sliding to the ground to some extent. In addition, as the principle, influences of inertia force, centrifugal force, Coriolis force, air resistance, air flow, and the like are considered.
The effect of the air flow may be the Magnes effect, which is explained by the Zhukovsky assumption.

[0009] The gist of the mower bogie according to the present invention is as follows. In the mower bogie, the mowing machine is manually moved forward while the cutting blade is floated on the ground, and the mower is moved substantially parallel to the ground. By rotating the parallel cutting blades in a certain rotation direction, the mower is moved forward around the rotation axis in the same direction as the certain rotation direction.

[0010] The mower truck of the present invention as described above, when the worker manually moves the mower forward while lifting the cutting blade on the ground, and when the operator releases his / her hand, is substantially parallel to the ground. Since the cutting blade is rotationally driven in a fixed rotation direction, the mower turns itself around the rotation axis in the same direction as the fixed rotation direction. When the mowing machine swings itself, the blade cuts the grass.

In this way, the operator moves the mower manually forward while lifting the cutting blade on the ground, and then repeats the operation of releasing the hand, so that the mower is lifted on the ground while the mowing blade is lifted on the ground. The operation in which the mowing machine is moved back by itself after the forward movement is repeated, and the grass on the ground is sequentially cut by the cutting blade.

Further, the gist of the mower bogie according to the present invention is as follows. In the mower bogie, the mower is linked to one of the forward and backward movements of the mower, and There is provided moving means for moving the mower in the direction of the tip portion by a predetermined amount.

[0013] The mower bogie of the present invention moves the mower toward the distal end thereof in conjunction with swinging in only one of the forward movement direction and the backward movement direction. That is, when the mower is swung in another direction, the mower does not move. Therefore, when rocking the mower in another direction, mowing is performed with the mower truck stopped.

Further, in the mowing method according to the present invention, a mowing machine provided with a mowing blade at a tip end portion, which is rotatably driven by a driving means, is mounted on a mowing bogie, and the mowing machine is set to be substantially parallel to the ground. Is a method of cutting the grass on the ground by moving the mower toward the tip while reciprocatingly swinging about the rotation axis of the cutting blade. By rotating and driving, the mower is moved forward or backward around the rotation axis in the same direction as the fixed rotation direction.

According to such a mowing method of the present invention, after the worker manually moves the mowing machine while lifting the cutting blade on the ground, when the operator releases his / her hand, the mowing is substantially parallel to the ground. Since the blade is rotationally driven in a certain rotation direction, the mower turns itself around the rotation axis in the same direction as the certain rotation direction.

The gist of the mowing machine according to the present invention is a mowing machine provided with a cutting blade, which is rotatably driven by a driving means, at a tip end thereof. By rotating a cutting blade substantially parallel to the ground in a fixed rotation direction by rotating a predetermined portion around the member in contact with the ground, the mowing machine is rotated around the rotation axis by the constant rotation. In the same direction as the direction of rotation. That is, the mowing machine of the present invention is a basic invention in which the cutting blade is rotated on the ground while rotating on the ground using the rotating force of the cutting blade, and the cutting blade is rotated on the ground using the rotating force of the cutting blade. The invention broadly includes a mower that cuts the grass while oscillating the mower by rolling in the above manner.

Such a mower can be operated, for example, by an operator manually moving the mower while floating the cutting blade on the ground, and then relaxing the holding force of the mower, or by moving the belt of the mower to the shoulder. By repeatedly moving the mower manually after moving the mowing blade forward on the ground while lifting the mowing blade on the ground, the mowing machine is moved forward while the mowing blade is floated on the ground. After that, the operation in which the mowing machine moves back by itself is repeated, and the grass on the ground is sequentially cut by the cutting blade.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of a bogie for a mower, a mowing method and a mower according to the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2, reference numeral 100 denotes a bogie for a mower according to the present invention. This mower truck 100
The mowing machine mounts the mower 12 and moves the mower 12 toward the tip of the cutting blade 14 while reciprocatingly swinging the mower 12 substantially in parallel with the ground, thereby mowing the ground. It is a dolly.

Here, the mowing cart 100 is rotated by the cutting blade 14 which is substantially parallel to the ground 112.
The mower 12 can move substantially parallel to the ground 112. That is, the bogie 100 for the mower can be
6 is held with the left hand, the lever 118 is held with the right hand, and the lever 118 is pressed and rotated clockwise, so that the mowing blade 12 is floated on the ground 112 while the mowing machine 12 is held.
Can be moved clockwise, and by releasing the lever 118, the mower 12 itself can move back counterclockwise.

Here, the mowing cart 100 is provided with a cutting blade 14.
The mounting table 120 is provided at a relatively low position so that the is parallel to the ground 112. The angle of the cutting blade 14 with respect to the rod 13 may be increased so that the vicinity of the rear end of the cutting blade 14 contacts the ground. Reference numeral 15 denotes a protective cover, the form of which is not limited at all.
It may be one that covers the vicinity of the upper part of.

Here, the bogie 100 for the mower is a mower 1
Moving means 124 is provided for rotating the wheel 122 by a fixed amount in conjunction with the clockwise swing of No. 2 to move the mower 12 forward, that is, toward the tip end thereof. Further, in order to prevent the mower 100 from moving backward, a movement direction restricting means 126 is provided.

The moving means 124 includes an arm 128 which swings integrally with the lever 118, a conversion jig 130 for converting the swinging movement of the arm 128 into a rotary movement, and a conversion jig 1.
And a belt 134 for transmitting the rotational movement of the belt wheel 132 to the wheels 122.
And The conversion jig 130 is, as shown in FIG.
A rotating member 136 that rotates in association with the arm 128, and a link 150 that is rotatably attached to the rotating member 136;
And 151, and a turning wheel 153 that is turned by the link 151. That is, the link 150 rotates the rotation member 136 in conjunction with the swing of the arm 128, so that the rotation shaft 142 can be rotated by a certain amount in one direction.

As shown in FIG. 3, the movement direction limiting means 126 includes a ratchet wheel 146 fixed to the wheel shaft 144, and a pawl member for rotating the ratchet wheel 146 only in one direction and stopping the rotation in the opposite direction. 148. That is,
The configuration is such that the wheel shaft 144 of the wheel 122 rotates only in one direction, and the mower bogie 100 does not move backward.

The mower truck 100 having the above-described structure is
First, the mower 12 is mounted on the mounting table 120, and the cutting blade 14 is rotated and used. With the mower 12 mounted, the operator holds the handle 116 in the left hand, holds the lever 118 in the right hand, and rotates the blade 118 clockwise while pushing the lever 118 downward. The mower 12 is moved clockwise while the 14 is floated on the ground 112.

Here, the forward movement of the mower bogie 100 is performed by rotating the lever 118 clockwise. First, when the lever 118 is swung to the left, the arm 128 integrated with the lever 118 is swung forward. When the arm 128 is swung, as shown in FIG. 3, the link 150 at the tip of the arm 128 pulls the turning member 136, and the turning member 1
36 is rotated about a rotation axis 142. When the rotation member 136 is rotated around the rotation shaft 142, the link 151 rotates the rotation wheel 153, and the belt wheel 132 is rotated. When the belt wheel 132 is rotated, the rotational motion is transmitted to the belt wheel 152 by the belt 134, and the belt wheel 152 is rotated. When the belt wheel 152 is rotated, the wheel 122 having the wheel shaft 144 that is the same rotation axis as the belt wheel 152 is rotated.

By rotating the wheels 122 in this manner, the mower bogie 100 moves forward, and the mower 12 moves toward the tip. Therefore, the mower bogie 100 of the present invention moves forward by a fixed amount only when the handle 118 is swung to the left (clockwise direction).

Next, when the operator releases the lever 118, the mower 12 returns by itself counterclockwise. That is, the mowing machine 1
2 will rock itself counterclockwise. Incidentally, when the present inventor actually went, the result was obtained that the mower 12 rocked itself counterclockwise only to the extent that the lever 118 was touched. In principle, since the rotating shaft 125 is slightly inclined from the vertical direction, the cutting blade 14 is parallel to the ground 112 when the cutting blade 14 is in the neutral position.
When the cutting blade 14 swings right or left, the cutting blade 14 is slightly inclined with respect to the ground 112, and a part of the cutting blade 14
It is considered that they contacted the surface 12 and rocked themselves by the reaction force from the ground 112. Actually, when the cutting blade 14 slightly swings to the left, the cutting blade 14 further swings to the left, so that the rotating shaft 125 slightly tilts forward, and the right rear vicinity of the cutting blade 14 comes into contact with the ground 112. It is considered something.

In this manner, the operation of holding the lever 118 in the right hand, rotating the lever 118 clockwise while pressing it downward, and then releasing the lever 118 repeatedly causes the cutting blade 14 to move The mowing machine 12 is moved forward in the clockwise direction while being floated on the 112, and after the mowing vehicle 100 is moved forward by a predetermined distance, the operation of the mowing machine 12 returning in the counterclockwise direction by itself is repeated. The grass of 112 is cut by the cutting blade 14 sequentially.

The mower bogie 100 provides
When mowing the bank from the top of the bank, use a screw 1
27, the rod 13 is rotated, and as shown in FIG.
By cutting the cutting blade 14 and loosening the screw 129 so that the lever 118 is tilted to the right, the mowing vehicle 100 is moved along the top of the bank while mowing the bank. Can be. In this case, the mowing machine 12 rotates around the rotating shafts 129 and 131 while the mowing blade 1 rotates.
4 swings along the slope.

According to the mower bogie 100,
By releasing the lever 118, the operator can cut the grass while swinging the mower 12 counterclockwise. For this reason, the fatigue of the mowing work can be reduced, and the mowing operation can be performed more easily.

Further, according to the mower bogie 100, the mower 12 is swung by using the rotating force of the mowing blade 14, so that even if the rod 13 of the mower 12 is protruded forward long, mowing can be performed. The machine 12 can be easily swung. This is convenient when an operator stands on top of the slope and mows the slope. In addition, since the mowing machine 12 is configured to be mounted at a relatively low position, it is convenient when an operator stands on the top of the slope and mows the slope.

Although the embodiments of the mower bogie and the mowing method of the present invention have been described above, the present invention is not limited to the above embodiments.

For example, as shown in FIG. 6, in the bogie 100 for mowers, the mowing machine 12 is driven by the reaction force from the ground 112 by rotating around the rear end of the cutting blade 14 while contacting the ground. The movement may be made substantially parallel to the ground 112. That is, the mower truck 100 is configured such that the operator holds the handle 116 with the left hand, holds the lever 118 with the right hand, and turns the cutting blade 14 clockwise while pressing the lever 118 to thereby move the cutting blade 14 to the ground 112. While the mower 12 can be moved clockwise while floating on the upper side, by releasing the hand from the lever 118, the vicinity of the rear end of the cutting blade 14 is brought into contact with the ground 112 and the ground 11
The mower 12 may be made to be able to move counterclockwise by the reaction force from the second.

The mower bogie 100 having such a configuration is as follows.
By rotating the lever 118 clockwise while pressing the lever 118 downward with the mower 12 mounted, the cutting blade 14
The mowing machine 12 is moved clockwise while floating on the ground 112, and the mower bogie 100 moves forward.
4 comes into contact with the ground 112 by its own weight. Rear end 1 of cutting blade 14 rotating counterclockwise
Since the vicinity of 4a is in contact with the ground 112, the rear end 14a
Mower 1
2 will return by itself counterclockwise. That is, the mowing machine 12 swings counterclockwise by itself while the mowing blade 14 rolls on the ground 112 by the rotational force of the mowing blade 14. Note that the cutting blade 14 does not completely roll on the ground 112, and may roll while sliding to some extent.
When the mower 12 swings itself counterclockwise, the blade 14
The grass is cut by the vicinity of the tip 14b.

In this manner, the operation of holding the lever 118 in the right hand, rotating the lever 118 clockwise while pressing it downward, and then releasing the hand from the lever 118 is repeated. The mowing machine 12 is moved forward in the clockwise direction while being floated on the 112, and after the mowing vehicle 100 is moved forward by a predetermined distance, the operation of the mowing machine 12 returning in the counterclockwise direction by itself is repeated. The grass of 112 is cut by the cutting blade 14 sequentially.

According to the mower bogie 100,
When the operator releases the lever 118, the rear end 14
Due to the reaction force from the ground 112 against a, the grass can be cut while rotating the mowing blade 12 on the ground 112 and swinging the mower 12 counterclockwise. For this reason, the fatigue of the mowing work can be reduced, and the mowing operation can be performed more easily.

In the mower bogie 100 of the present invention, the conversion jig may be a conversion jig 180 shown in FIG. The conversion jig 180 is configured to be able to expand and contract the link 184 by rotating the cylindrical member 182. Further, the position of the link 151 with respect to the rotating member 186 fixed to the rotating shaft 142 can be changed. That is, by rotating the screw 188, the engaging member 190 moves in the direction of the screw 188, the point of action of the link 151 on the rotating member 186 moves, and the amount of rotation of the rotating member 186 can be adjusted. It is configured.

According to such a conversion jig 180, the swing angle of the mower 12 can be adjusted by expanding and contracting the link 184. Further, by moving the screw 188 to adjust the amount of rotation of the rotating member 186, it is possible to adjust the moving distance of the mower bogie 100 per one swing of the lever 118. Therefore, the moving distance of the bogie 100 for one rotation of the lever 118 can be adjusted according to the size of the cutting blade 14 and the like.

Next, a mower truck 10 as shown in FIGS. 8 and 9 may be used. The mower truck 10 has a mower 12 mounted thereon, and the mower 12 is moved in the direction of the tip having the cutting blade 14 while reciprocatingly swinging the mower substantially in parallel with the ground 112, whereby 112 is a mowing cart for mowing grass. The mower truck 10 is configured such that the operator holds the handle 16 with the left hand and swings the lever 18 right and left while holding the lever 18 with the right hand, so that the mower 12 is fixed to the mounting table 20 integrated with the lever 18. Is swung left and right, but the vicinity of the rear end of the cutting blade 14 is
2.

The mower truck 10 rotates the wheels 22 by a fixed amount in conjunction with the swinging motion of the mower 12 to rotate the mower 1.
Moving means 1 for moving 2 forward, that is, in the direction of its tip
24 are provided. Further, in order to prevent the mower bogie 10 from moving backward, the moving direction restricting means 2
6 are provided.

The moving means 24 includes an arm 28 swinging integrally with the lever 18, a conversion jig 30 for converting the swinging motion of the arm 28 into a rotary motion, and a belt wheel rotated by the conversion jig 30. 32 and a belt 34 for transmitting the rotational movement of the belt wheel 32 to the wheels 22. As shown in FIG. 10, the conversion jig 30 is rotated by the rotation member 36, the claw member 38 rotatably attached to the rotation member 36, and the claw member 38. And a rotating shaft 42 to which the ratchet wheel 40 and the belt wheel 32 are fixed.

That is, the pawl member 38 pushes the ratchet wheel 40 in conjunction with the swing of the arm 28, so that the rotary shaft 42 can be rotated in one direction by a fixed amount. . A release means 43 is provided for pushing up the claw member 38 to release the engagement with the ratchet wheel 40. By turning the knob 45 of the release means 43, the claw member 3 is rotated.
8 can be pushed up.

As shown in FIG. 11, the moving direction restricting means 26 includes a ratchet wheel 46 fixed to the wheel shaft 44, and a pawl member for rotating the ratchet wheel 46 in one direction and stopping the rotation in the opposite direction. 48. That is, the wheel 22
Is configured to rotate only in one direction, so that the mowing vehicle 10 does not move backward.

The forward movement of the mower truck 10 is performed by swinging the lever 18 to the left. First, the lever 18 is swung to the left,
The arm 28 integrated with the lever 18 is swung forward. By swinging the arm 28, FIG.
As shown in FIG. 7, the turning member 36 engaged with the engaging member 50 at the tip of the arm 28 is turned around the turning shaft 42. The pawl member 38 pushes around the ratchet wheel 40 by rotating the rotary member 36 about the rotary shaft 42. When the ratchet wheel 40 is pushed around, this ratchet wheel 40
The rotating shaft 42 to which is fixed is rotated. When the rotation shaft 42 is rotated, the belt wheel 32 fixed to the rotation shaft 42 is rotated. When the belt wheel 32 is rotated, the rotational motion is transmitted to the belt wheel 52 shown in FIG. 11 by the belt 34, and the belt wheel 52 is rotated. When the belt wheel 52 is rotated, the wheel 22 having the wheel shaft 44 that is the same rotation axis as the belt wheel 52 is rotated. When the wheels 22 are rotated, the mower truck 10 moves forward, and the mower 12 is moved in the direction of the tip.

Next, when the operator releases the lever 18, the vicinity of the rear end of the cutting blade 14 comes into contact with the ground 112 by its own weight. Cutting blade 1 rotating counterclockwise
4 Because the rear end vicinity 14a is in contact with the ground 112,
Due to the reaction force from the ground 112 to the vicinity of the rear end 14a, the mower 12 moves back counterclockwise by itself. In this manner, by holding the lever 18 in the right hand, repeatedly rotating the clockwise clockwise while pressing the lever 18 downward, and then releasing the hand from the lever 18, the cutting blade 14 is placed on the ground 112. The mowing machine 12 is caused to move clockwise while being floated, and at the same time, the mowing machine 10 is advanced by a predetermined distance, and then the mowing machine 12 is moved back counterclockwise by itself.
Is cut by the cutting blade 14 sequentially.

Here, when the handle 18 is released, the arm 28 is swung rearward, and the turning member 36 is turned in the opposite direction. Even if the rotating member 36 is rotated in the reverse direction, the claw member 38 does not engage with the ratchet wheel 40, so that the ratchet wheel 40 does not rotate. Since the ratchet wheel 40 does not rotate, the mower bogie 10 does not move while stopped. That is, when the handle 18 is swung to the right, the mowing machine 12 is swung and mowing is performed with the mower bogie 10 stopped. Since the mower 12 is swung while the mower bogie 10 is stopped, the grass on the ground 112 is evenly cut.

Therefore, the mower bogie 10 of the present invention moves forward by a fixed amount only when the handle 18 is swung to the left. When the mower 12 is swung over a certain angle or more, the pin head 51 of the rotating member 36 interferes with the engaging member 50. For this reason, the swing angle of the mower 12 is limited to a fixed value.

Next, if the cutting blade 14 hits a stone or the like or goes up a slope, a force for moving the mower bogie 10 backward is exerted. When the force for moving the mower truck 10 backward acts, the wheel shaft 4 of the wheel 22 is moved.
A force acts such that 4 rotates in the opposite direction. However, FIG.
The rotation of the ratchet wheel 46 fixed to the wheel shaft 44 in the reverse direction is stopped by the pawl member 48 by the movement direction restricting means 26 shown in FIG. Since the wheel shaft 44 does not rotate in the reverse direction, the mower truck 10 is prevented from moving backward.

The mower truck 1 without mowing
To move 0, the knob 45 of the releasing means 43 is turned to push up the claw member 38 to release the engagement of the claw member 38 with the ratchet wheel 40. Since the engagement of the claw member 38 with the ratchet wheel 40 is released, the mower bogie 10 can be pushed and moved without swinging of the mower 12.

According to the mower bogie 10 described above, the mower 12 is mounted on the mounting base 20 and is fixed, and the lever 18 is swung right and left to move the mower 12 to the ground 112.
By moving the mower 12 forward by a predetermined amount while reciprocating and swinging substantially parallel to the above, the grass growing on the ground 112 can be mowed. For this reason, by mounting the heavy mowing machine 12, the mowing machine 12 does not need to be gripped by a worker with a strong force, and mowing can be easily performed. Further, the vibration of the mower 12 is not directly transmitted to the worker, and there is no fear of damaging the worker's body. Also, mower 1
The mowing machine 12 can be easily moved since the mowing machine 12 can be moved by utilizing the swinging motion. Further, by moving the mower 12 by a fixed amount, the grass on the ground 112 can be evenly cut.

When the mower 12 is swung over a certain angle or more, the pin head 51 of the rotating member 36 interferes with the engaging member 50, so that the swiveling angle of the mower 12 can be limited to a certain value. it can. For this reason, it is possible to prevent the mowing machine 12 from swinging too much and the cutting blade 14 from hitting an operator or the like, and it is possible to enhance safety.

Further, the moving direction restricting means 26 can prevent the mower bogie 10 from moving backward. For this reason, even if the cutting blade 14 hits a stone or the like or goes up a slope, the bogie 10 for mowing is not moved backward, and the mowing machine 12 is prevented from moving in the direction of the worker. As a result, safety can be improved.

The mower truck 10 can be moved forward when the lever 18 is swung to the left, and stopped when the lever 18 is swung to the right. For this reason, the lever 18
Is swung to the right, the mower bogie 10 is stopped, and the grass can be evenly cut while the mower 12 is swung.

In such a mower bogie 10 as well,
By rotating the lever 18 clockwise while pressing the lever 18, the mowing machine 12
Can be moved clockwise, while the release of the lever 18 allows the mower 12 to return itself counterclockwise.

Next, the mower used in the mower truck of the present invention is not limited to the mower 12 described above, but may be a mower 160 as shown in FIG. This mower 1
60 is the cutting blade 1 via gears 162, 163 and 164.
A rotating member 168 that rotates together with 66 is provided.
The mower 160 can be used by being mounted on the mower cart 100 or 10 or the like, but can also be used by being directly held by an operator without being mounted.

For example, when the operator directly uses the mowing machine 160 while holding the cutting blade 166 on the ground 112, the operator first moves the mower 160 forward. Next, the rotating member 168 rolls on the ground 112 while contacting the ground 112 by loosening the holding force of the mower 160 or releasing the hand while the belt of the mower 160 is hung on the shoulder or the like. The mower 160 moves back by itself. Therefore, by repeating such an operation, the grass on the ground 112 is sequentially cut by the cutting blade 166.

Further, a mower 170 as shown in FIG. 13 may be used. The mower 170 includes gears 172, 17

[0062]

According to the mower bogie of the present invention, it is possible to mowing the grass while rocking the mower itself with the lever and the like released. For this reason, the fatigue of the mowing work can be reduced, and the mowing operation can be performed more easily. Also,
Since the mower can be swung without using a driving force, costs such as fuel costs can be reduced, and a compact configuration can be achieved.

The mowing machine is manually moved forward while the mowing blade is lifted on the ground, and the mowing blade substantially parallel to the ground is driven to rotate in a fixed rotational direction. According to the mower bogie of the present invention, a force for moving the mower forward in the same direction as the fixed rotation direction can be applied to the mower while the worker lifts the mowing blade on the ground. By repeating the operation of releasing the hand after moving forward, the mowing machine can be moved back by itself after the mowing machine is moved forward while the cutting blade is floated on the ground. For this reason, the worker can successively mow the grass on the ground with the cutting blade only by repeating the operation of moving the mower forward and releasing the hand while floating the cutting blade on the ground.

Further, the present invention is characterized in that there is provided moving means for moving the mower in the direction toward the tip end by a fixed amount in conjunction with the forward or backward movement of the mower in one direction. According to the mower bogie described above, when the mower is swung in one direction, the mower can be moved in the direction of the tip, and when swung in the other direction, it can be stopped. For this reason, when the mower is swung in the other direction, the mower bogie is stopped, and the grass can be mowed evenly while the mower is swung.

Further, according to the mowing method of the present invention, the mowing machine can swing itself. For example, when the vicinity of the rear end of the rotating cutting blade is in contact with the ground, the mower can be swung by a reaction force from the ground with respect to the vicinity of the rear end.

According to the mower of the present invention, it is possible to cut the grass while swinging the mower by the action of the mower itself.
For this reason, the fatigue of the mowing work can be reduced, and the mowing operation can be performed more easily.
