Description

  The present invention relates to a management work machine that performs weeding by cultivating topsoil while advancing between crops.

  So-called medium-plowing weeding, which improves soil air permeability and drainage by plowing soil between furrows and controls weeds, is performed using a management work machine. This work is performed several times a year depending on the crop, and the ratio of the working time of the middle tillage work to the total working time of the cultivation of the crop is large.

  Middle plowing weeding with a management machine is effective in reducing work time and labor load. There are many types of management work machines, such as a small walking type that travels between ridges and shares an axle and a tilling shaft, and a riding type that travels across a ridge with four wheels.
