<p>Blade assemblies for use with compacting vehicles are normally designed to push the material in front of the blade and to control the height of the material passing thereunder for compaction by the compacting vehicle. In the subject arrangement, a blade assembly (12) is provided and includes a blade (32) pivotally connected to a frame (30) having a working edge (62) that permits, during use, level spreading of trash and/or soil when the blade is in a first operative position. When the blade assembly (12) is raised and the blade (32) is pivoted forwardly with respect to the frame (30), a first portion (70) of the working edge (62) controls the volume of trash and/or soil allowed to pass under the working edge (62) between respective compacting mechanisms (16, 18) of a compacting vehicle (10). The remaining portion (72) of the working edge (62) controls the volume of trash and/or soil subjected to the respective compacting mechanisms (16, 18) for compaction thereof. By controlling the volume of trash permitted to pass under the first portion (70) of the working edge (62), detrimental wear of the components under the compacting vehicle (10) is substantially eliminated.</p> |
