PROBLEM TO BE SOLVED: To solve a problem in a conventional seeding machine that cannot properly cover fertilizer with soil.SOLUTION: A seeding machine or a working machine is characterized by including: a direct seeding device 47 for scattering seed on a field; a fertilizing device 5 for feeding fertilizer in a field; a seed grooving unit 64 for forming seed grooves where the seed scattered in the field gets therein in the field; a fertilizer grooving unit 1100 for forming fertilizer grooves where the fertilizer supplied in the field gets therein in the field; a seed soil covering plate 59 for covering up the seed with soil to the seed getting into the seed grooves formed in the field, and capable of adjusting an attitude; a fertilizer soil covering plate 1200 for covering the fertilizer getting into the fertilizer grooves formed in the field with the soil, and capable of adjusting the attitude; a connecting rod 1300 for connecting the fertilizer soil covering plate 1200 so that the fertilizer soil covering plate 1200 may be linked with the seed soil covering plate 59; a hardness sensor 87 for detecting the hardness of the soil in the field; and an adjusting mechanism 1400 for adjusting the attitude of the seed soil covering plate 59 or the fertilizer soil covering plate 1200 according to the hardness of the detected soil. |
