SOIL DISINFECTOR

PROBLEM TO BE SOLVED: To solve the problems of a conventional soil disinfector attached to a walking-type plant husbandry machine having constructional elements of the soil disinfector placed usually on an attaching frame of the husbandry machine, keeping a high load applied to a worker in the case of using a heavy chemical tank to be placed near the top of the husbandry machine and large variation of the longitudinal weight balance of the machine body according to a consumption of the chemicals owing to the separation of the tank from axle of a traveling wheel. SOLUTION: The attaching frame 67 for attaching a plurality of constructional elements including the chemical tank 30 is fixed at the front or rear end of the husbandry machine 2, arms 69/70 are placed at right and left of the attaching frame 67 interposing the husbandry machine 2 between the arms, the arms 69/70 are positioned near a horizontal plane 77 passing the upper end of the traveling wheels 3L/3R on rotation planes 79L/79R of the traveling wheels 3L/3R or at right and left outside of the planes, the chemical tank 30 is placed on at least one of the arms 69/70, and the gravity center 30c of the chemical tank 30 is positioned within longitudinal width 78 of the traveling wheels 3L/3R by plane view.
