LIQUID DISTRIBUTION ELEMENT A rotary element for distributing a liquid such as a herbicide comprises liquid distributing projections (58) which have swept-back leading boundary surfaces (64) which are arcuately convex. Each projection (58) has a transverse surface (62) which is arcuately concave and extends forwardly from one axial end of the respective leading boundary surface (64), with respect to the direction of operative rotation of the element. This configuration enables the spray width of the liquid to be reduced.
