Abstract
A rotary element (8), for distributing liquids such as herbicide, comprises a concave liquid receiving surface (22) including a conical outer portion (26). Teeth (28) project from the outer portion (26). Each tooth has an upper surface (30) which is inclined to the rotary axis of the element by a greater angle than is the outer portion (26). Each tooth has side surfaces (32) which extend parallel to the rotary axis and have a maximum axial dimension (t) which is greater than 0.01, and preferably 0.05, times the overall diameter of the element.
