Abstract:
A pull spreader for spreading a surface material on a path, comprising:a. an open-bottomed frame having a first side wall and an opposed second side wall, a front wall secured between the first and second side walls and a screed wall opposed to the front wall and extending between the first and second side walls so that the first and second side walls, front wall and screed wall cooperate to define a storage chamber between the walls for storing the surface material, wherein the storage chamber has a planar inlet area defined between top edges of the first and second walls, the front and screed walls that is no greater that one-hundred and twenty-five per cent of a planar discharge area of the storage chamber, which planar discharge area is defined between bottom edges of the first and second walls, the front and screed walls adjacent to the path; b. steering means for controlling a direction of travel of the pull spreader secured to a front frame extension affixed to the open-bottomed frame adjacent the front wall and extending away from the storage chamber; c. a pull coupling means secured to the open-bottomed frame for attaching a cable to the front frame extension that permits the pull spreader to be pulled over the path by the cable; and, d. a screed discharge means secured to the open-bottomed frame adjacent the screed wall and extending away from the storage chamber for adjustably forming the surface material passing out of the storage chamber.
