PURPOSE:To prevent waste straw from twining around a furrower and fertilizers, etc., from sticking to the inner surface of the furrower, by constituting one side plate of the furrower in the form of almost U or V in the plan view of a disk downward rotatable to the forward direction on the horizontal shaft center. CONSTITUTION:A side plate (13a) in the form of a disk is rotatably supported on the horizontal shaft center (P2) of a bracket of a float 17 and a side plate (13b) in the form of J in the plane view is fixed through a furrowing member 18 to the float 17. A hose 12 is mounted on the side plate (13b) through a rubber bushing 27 to feed a fertilizer passing through the hose 12 into a gap between the front side part of the side plate (13b) and the horizontal shaft center (P2).
