Material spreaders, in particular fertilizer dispensers are disclosed that comprise a frame, a hopper (1) and distribution members (4, 5 or 84, 85) at least one of which is movable about an upwardly extending rotary axis with respect to the frame and/or the hopper, which can be set askew transversely of the normal direction of travel (10 or 93) of the device over a surface on which material is to be spread, and which is fixable optionally in one of at least two different positions. This spreader can be readily set for acting on the distribution pattern (27 or 28 or 106) of the material as spread by the spreader and, in particular, a peripheral strip of a surface to be covered, within the distribution pattern, can be arranged to have material spread uniformly over its entire width (17) with a boundary edge that is sharply defined. <IMAGE> |
