An edge bag arrangement (50) is fitted to a spray tree frame (30, 34, 36) and extends downwards from the frame. It has a bottom edge which is arranged close to the ground. The edge bag arrangement (50) forms a casing which is open to the ground. An injection device (24) delivers compressed air into the edge bag arrangement and into the space (52) enclosed by it. Consequently the tree and the edge bag arrangement are held above the ground. A delivery device (86) for the spray is fitted to the tree to deliver the liq. into the space enclosed by the edge bag arrangement. |
