ABSTRACT:
A dozer blade of the present invention includes two curved blade sections that are joined at respective inner ends thereof. The blade sections are joined to form a unitary blade exhibiting a concave surface for scraping and removal of snow and the like. The blade sections converge forwardly at the top toward their central juncture such that a top portion of the central juncture is generally positioned forwardly of a bottom portion thereof. Additionally, the top portion of the central juncture is generally positioned lower than outer ends of respective top portions of the blade sections, presenting a winged profile from the front. A divider is positioned along the central juncture from a bottom scraping portion of the blade sections to the top. The divider serves to distribute material being dozed generally equally to either side.
