2. Description of the Related Art A riding tractor or a walking tractor equipped with a working machine such as a shore coater, a mowing machine, a fertilizer spreader, or a pesticide spreader makes it difficult to work on narrow ridges. It was a method of installing a side coating machine on a tractor or a walking tractor and running from the rice field to perform the side coating work, which was basically done before planting rice in the Honda preparation period. In addition, the mowing work is mainly performed by a manual shoulder-powered mower. In addition, the fertilizer spraying work, pesticide spraying work, and herbicide spraying work on the shore after planting rice were carried out manually by a backpack type, backpack type power spraying machine, or only a part of the paddy field management machine / radio control helicopter.

[Problems to be Solved by the Invention]

[0004] In order to perform work such as shore leveling for managing paddy fields, shore coating, mowing, fertilizer application, pesticide application, and herbicide application on the shore, various work machines are attached to the machine body, and road surfaces such as narrow shores are installed. It was necessary to have a self-propelled paddy field management machine that can be safely used for work.

[0005] For example, the maintenance of the shore to enhance the water storage capacity requires work before and after rice planting, and the water required for growing rice is important especially for 60 days after rice planting. is there. The maintenance and maintenance of the above-mentioned shoreline is usually done with a shore coater before the cultivation of Honda once a year.
Most of them are destroyed by the mole in the day or the first week, and the repeated use of herbicides on the shore during the cultivation period expands the shore collapse phenomenon and weakens the shore structure. .

Therefore, it is to repel the moles by vibrating them while at the same time increasing the strength by compacting the shore. For that reason, a shore leveling machine was required to maintain the shore with a high-strength structure.

When a tractor is connected to a shore coater or a ground leveling machine to work, a wing coat and a ground leveling unprocessed section are generated due to the direction change of the machine body. As a result, the rework burden due to human power is large, and the untreated section is further expanded due to the spread of the large size of the tractor, and the human labor burden is also increasing. In addition, with the expansion of farming contracts for large-area farming, the untreated section is constantly left unattended, and the number of fields with impaired paddy field storage tends to increase. In order to reduce the untreated section caused by the machine turning, it was necessary to install a shore smoothing machine or a shore spreading machine that is installed using an integrated compact paddy field management machine.

According to the present invention, based on the experience accumulated by the applicant for 32 years or more in the production site, the machine effectively runs on a narrow shore, and various working machines are attached to the machine before and after rice planting. Focusing on the need for paddy field management machines that can be used as
It was devised with the hope that it will be released from the heavy labor associated with the scale expansion in the land preparation, mowing, fertilizer spraying, pesticide spraying and herbicide spraying work that must be done after planting the rice paddy manually. is there.
