However, if only the mechanical structure is used,
When switching the operation, the operator must confirm the positional relationship between the two operation levers one by one. In addition, in order to connect the two operation levers, it is necessary to rotate one operation lever once in a direction orthogonal to the normal operation direction so as to approach the other operation lever. The required operation becomes complicated, and the required area of the operation unit must be increased.

Next, the operation control according to this configuration will be described. When the tractor 1 is advanced in the field and the rotary tilling machine 2 is lowered to perform the tilling operation, the traveling lever 12 is set to the low gear position. The sensing sensor 23 issues an ON signal. The operation lever 13 is set to a non-operation position, which is an ascending position of the rotary tiller 2.
Next, when the clutch of the work mission 11 is turned on, the switch 10 is turned on, and the control device 24 is switched to the work mode. And O in this work mode
N or ON of the switch 10 and O of the sensing sensor 23
The control device 24 determines the AND state with the N signal, turns on the operating means 20, and the pin 21 as a connecting member protrudes and fits into the locking groove of the traveling lever 12 so that both levers 12,
13 is connected. In this state, when the operation lever 13 is moved forward and the rotary tiller 2 is lowered,
Since the traveling speed of the tractor 1 is also set at the high speed position, the field is plowed at high speed.

When turning the tractor 1 at the end of the field, it is necessary to raise the rotary cultivator 2 once, and the traveling speed of the tractor 1 must be reduced for safe operation. At this time, when the operation lever 13 is rotated rearward, which is the non-working position, the traveling lever 12 can also be automatically positioned at the low gear. In this manner, the running speed of the tractor can be switched between the low speed stage and the high speed stage only by operating the operation lever 13 during the tilling operation.

Next, in a traveling mode such as traveling on a road, the clutch of the work mission 11 is turned off, and the switch 10 as mode switching means is also turned off. Is in the low-speed position, the control device 24 does not turn on the actuating means 20, so that the traveling lever 12 and the operating lever 13
Can be maintained in a blocked (released) state. In this traveling mode, the traveling lever 12 can be moved back and forth by itself, and can be arbitrarily set from the high speed gear to the reverse position.

[Operation and Effect of the Invention] As described above, the operating device of the present invention for towing a tractor or the like is used for towing traveling of a tractor or the like which is connected to a working machine such as a rotary cultivator so as to be able to move up and down. On the vehicle, a traveling lever for changing the traveling speed and an operating lever for setting a working position such as raising and lowering the working machine are arranged close to each other, and the moving directions of the two levers are parallel to each other. In the operating device set so that either one of the traveling lever and the operating lever is provided with an interlocking member detachably connected to the other lever and its operating means, and the traveling lever has a low speed The movement range in which the gear is rotated from the gear position to the high gear position and the movement range in which the operation lever is rotated from the work position of the work implement to the non-work position correspond to each other, and the traveling lever is in the neutral position and the retreat position. When the operation mode is switched to the work mode, the mode switching switch for controlling the operation lever to not be positioned in the range of movement and switching between the drive mode and the work mode is turned on. When the two levers are arranged sideways in the work mode, the two levers are connected to the image recognition means via the operating means and the connecting member. By simply moving the lever, it is possible to execute quick work. The operating lever and the traveling lever only need to have a space enough to move in parallel with each other. Even if one of the levers is not moved in a direction orthogonal to the moving direction, the operating lever and the connecting member can be used to move both levers. Since the connection state and the release state can be selected, there is an effect that the structure is extremely simple.
