PROBLEM TO BE SOLVED: To provide a plant husbandry machine capable of finely adjusting the angle of a disk unit relative to the traveling direction by reversing the direction of the unit relative to the traveling direction without removing the disk unit from a lateral supporting rod at the back of an attachment frame and capable of varying and adjusting the gap between the right and left disk units. SOLUTION: A gyration shaft is placed at the top of a vertical shaft of a disk unit, the vertical shaft is supported in a manner rotatable relative to the supporting bracket f, the gyration center of the vertical shaft on the gyration shaft is longitudinally deviated from the longitudinal center of the lateral shaft 20 by a prescribed eccentric distance, a fixing bolt 34 for fixing the attaching bracket of the vertical shaft to the supporting bracket f is inserted into the bolt hole of the attaching bracket and the long hole of the supporting bracket f, and the attaching bracket is fixed to the supporting bracket with the fixing bolt to fix the vertical shaft.
