A spreading apparatus for hitching to a helicopter includes a hopper suspended from a ring, three tubular legs with upper ends releasably attached to the ring, and a strut between each pair of legs. A plurality of tension cables are provided, each cable having a top end joined to the ring at a leg attachment point and a bottom end joined to a rubber roller inserted between adjacent struts where they attach to a leg with a coupling. A rotatable distributing disk having essentially radial distributing fins is positioned concentrically underneath an opening in the bottom of the hopper. The disk is larger than the opening and spaced therefrom so that bulk material in the hopper attains its angle of rest without overflowing the disk when the disk is stationary, thereby preventing escape of the bulk material. The disk is preferably a shallow dish.
