Abstract
A lawn spreader includes an elongated generally rectangular hopper supported by a set of wheels and having a bottom member formed by a longitudinally extending aluminum extrusion. The extrusion has upwardly projecting inclined flange portions which are secured to the inclined side walls of the hopper, and the flange portions are integrally connected by a lower portion defining a longitudinally extending guideway. A slide member is supported within the guideway and is also formed from an aluminum extrusion. The slide member includes a longitudinally extending integral rib which projects downwardly and connects directly with the lower end portion of a control lever pivotally supported by a side wall of the hopper. The upper end portion of the lever engages a rotatably adjustable cam for precisely positioning the slide member to regulate accurately the discharge of material from the hopper through a set of spaced apertures within the extrusions. A push-type handle member projects upwardly from the hopper, and means are provided for converting the handle member into a tow bar adapted to be pulled by a motor vehicle such as a garden tractor.
