Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work control device for an agricultural working machine such as a tractor equipped with a rotary tiller.

[0002]

2. Description of the Related Art Conventionally, the vehicle speed of a tractor and the P of a cultivator are determined by the work content such as plowing or scraping and soil conditions in the field.
There was a technology to set the TO rotation and horizontal control sensitivities and plowing depth, and to perform agricultural work automatically.

[0003]

In the above prior art, when the operator inputs the setting of the working condition by operating a large number of switches, the setting operation at the start of the work is extremely troublesome, and the setting operation is forgotten or the setting value is not set. Automatic control malfunctions due to erroneous input, etc., and when a single or a few switches that automatically set general work conditions under general field conditions are provided, the average conditions for automatic control are set and input. However, there is a problem in that it is not possible to easily obtain automatic control suitable for a field or work in a specific area.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is provided with an agricultural work card in which field conditions or working conditions are recorded,
By configuring the working conditions to be set automatically by attaching the card to the data reader of the agricultural work machine, by recording the soil conditions and working conditions of the farm field in the area where the agricultural work is performed on the card. , The initial setting input of automatic control can be performed only by reading the data on the card, and it is possible to easily prevent forgetting the setting operation or erroneous input of the set value, etc., and automatically adjusting the field or work in a specific area. The control can be easily obtained, and the handling operation can be simplified and the adaptability of the automatic control can be easily improved.
