Description

The present invention mainly relates to a marking instrument for assisting agricultural work.

From the past, "puddling" has been performed as one of the agricultural works in paddy fields. Paddy plowing is the work of flattening the surface of the soil by crushing the soil finely and stirring it in a paddy field filled with water.

In modern times, the use of agricultural machinery such as tractors for puddling has dramatically improved work efficiency. However, in order to plow the entire field, even with agricultural machinery, it is necessary to go back and forth in a straight line many times from the edge.

At this time, there was a problem that one side of the field became muddy after plowing, making it difficult to know how far the plow had been plowed.

In order to solve such problems, various marking methods have been proposed for the purpose of marking the direction of agricultural work.

For example, Patent Literature 1 describes a marking method in which ropes are stretched across both banks of a field in a direction transverse to the traveling direction of an agricultural machine, and signs are attached to the ropes at appropriate intervals. ing.
