BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clutch operating device for mowers and the like, and is used for mowers and other agricultural working machines equipped with a clutch for traveling transmission and a clutch for operating transmission separately operated. Furthermore, the present invention is not limited to a traveling type working machine such as a hand tractor, but can also be used for a riding operation type combine, a seedling planting machine, and the like.

2. Description of the Related Art When the traveling clutch lever is disengaged, the working clutch lever is also operated in disengagement in conjunction with this to improve the operability. In such an operation mode, it is necessary to open and close the work clutch lever each time the traveling clutch lever is turned on and off, which limits operability.

SUMMARY OF THE INVENTION According to the present invention, a disengaged position of a traveling clutch lever 1 for turning on and off a traveling clutch by rotating in a front-rear direction and an on position of a working clutch lever 2 for enclosing and disengaging a working clutch are turned on. Is a configuration of a clutch operating device such as a mower that is set to the approaching position.

[0004]

When the traveling clutch lever 1 is placed in the disengaged position OFF and the work clutch lever 2 is also placed in the disengaged position OFF, both clutch levers 1 and 2 are in a front and rear separated relational position. When the work clutch lever 2 is turned to the ON position from this state, the work device is driven. Since the traveling clutch lever 1 is located near the ON position of the work clutch lever 2, the operating hand is changed to the traveling clutch lever 1 to operate from the traveling clutch disengaged position OFF to the engaged position ON, Work can be performed while traveling on the vehicle body.

When the traveling clutch lever 1 disengages the traveling clutch and then the working clutch lever 2 is operated to the engaged position ON, it may be operated in the opposite direction. As described above, in a series of related continuous operations of the traveling clutch lever 1 and the work clutch lever 2, both levers 1 and 2 can be smoothly held by exchanging them with the same hand. Since it can be performed independently, the configuration and operation can be simplified.

1 and 2, the rear end of the steering handle 3 of the mower is formed in a left-right loop shape, and the grip 4 is bent upward. A traveling clutch lever 1 and a working clutch lever 2 bent in a crank shape are supported by brackets 5 on both left and right bases of the grip portion 4 so as to be rotatable back and forth. The traveling clutch lever 1 has a front end behind the working clutch lever 2, and the working clutch lever 2 is located inside the traveling clutch lever 1.
Is configured to be rotatable. Reference numeral 6 is a pivotal support portion of the traveling clutch lever 1 with respect to the bracket 5, and 7 is a pivotal support portion of the work clutch lever 2.

A state in which a wire arm 8 is formed at the base of the traveling clutch lever 1 and a clutch wire 9 is connected so that the traveling clutch of the vehicle body can be turned on and off, and the traveling clutch lever 1 is brought close to the grip portion 4. The running clutch can be turned to the ON position by turning to the OFF position by rotating backward. Further, the work clutch lever 2 connects the clutch wire 11 near the pivotal support portion 7 via the spring 10, and the connecting position of the spring 10 with respect to the work clutch lever 2 is pivoted by the vertical rotation of the work clutch lever 2. It is possible to switch between the tensioned state and the loosened state by crossing the dead center with respect to the supporting portion 7. In this tensioned state, the work clutch is engaged and the work clutch lever 2 is
When the vehicle is moved upward, it is in an ON position ON which is slightly higher than the OFF position of the traveling clutch lever 1, and in a loose state, it is in a OFF position where it is rotated downward.

The bracket 5 on the side where the clutch wires 9 and 11 are provided is a seat 12 for receiving the pivotal support portions 6 and 7 of the traveling clutch lever 1 and the working clutch lever 2.
The outer side 13 is formed in a U-shaped groove shape with the outer side covered and the rear side opened, and if the pivotal support portions 6 and 7 are fitted from this open portion, the clutch wires 1 and 11 are pulled, respectively. It is configured to be able to hold the two pivot positions.

In the case of the mower, the clutch which is interlocked by operating the work clutch lever 2 engages and disengages the rotation transmission of the cutting blade, and when the transmission is disengaged, the brake is interlocked so that the cutting blade is rotated. It also has a configuration that doubles as a unit. 3 and 4 are different from the above example in that the left and right sides of the pivotal support 7 of the working clutch lever 2 are
An arm 14 connecting the spring 10 and a stopper 15
As a unit, the pivotally supporting portion 7 between the arm 14 and the stopper 15 is fitted and supported by the inverted U-shaped receiving seat 13. The seat 13 is open on both left and right sides, and the arm 14 is in a relationship of protruding to the outer side.

5 to 7 are different from the above example in that the traveling clutch lever 1 is provided on the rear side of the grip portion 4 of the steering handle 3 and the work clutch lever 2 is arranged on the grip portion 4.
It is provided on the front side of, and is configured to be turned on at the position where both are turned so as to approach the grip portion 4 side. Reference numeral 16 is a spring that connects the traveling clutch lever 1 and the wire 9. Reference numerals 17 and 18 denote stoppers which are engaged with each other when the clutch levers 1 and 2 are in the engaged position ON.
