Dirt distribution method

A method of removing an elongated mound of earth, defined by a longitudinal axis bordering the longitudinal edge of a road having an top surface above which said mound projects, without need to truck away quantities of accumulated removed earth, which comprises in combination the steps of:

• providing a bulldozer/grader machine comprising:
• an earth moving blade defined by a lengthwise bottom edge, a forward side edge, a rearward side edge and a front face upstanding from said bottom edge between said forward and rearward side edges and
• having attached thereon by clamp means a dirt distribution device comprising:
• an elongated arm defined by a longitudinal axis, an inboard end section and an outboard end section, said arm being pivotally mounted by said inboard end section to said clamp means,
• a platform defined by an inboard end portion, an outboard end portion, a forward side and a rearward side,
• pivot means comprising a shaft defined by a forward segment and a rearward segment mounting said platform by said inboard end portion upon said outboard end section of said arm for pivotal movement of said platform about an axis normal to said longitudinal axis,
• prop means to brace said pivot means relative to said arm,
• motor means carried upon said platform,
• dirt sling means rotatably carried by said motor means,
• inboard adjustment means to vary the radial position of said arm relative to said clamp means, and
• outboard adjustment means to vary the radial position of said platform relative to said arm,
• positioning said earth moving blade diagonally across said longitudinal axis with said lower edge penetrating said mound to slightly above said top surface of said road,
• moving said blade forward along said longitudinal axis thereby to move portions of said mound immediately in front of said front face across said front face toward said rearward side edge as a continuous ribbon of said earth to thereby bring said ribbon of said earth into contact with said dirt sling means, and
• rotating said dirt sling means thereby to disintegrate said ribbon into small pieces of earth that are thrown away from said rearward side edge.
