摘要

Improvements introduced in the drag shovels of materials for grading and similar works, essentially characterized by comprising the arrangement of a pushing surface of any kind of aggregate, this plane constituting the blade itself, whose anterior part is curved longitudinally and symmetrically, presenting a lower band as a removable and replaceable complement, of a straight plane, being conveniently fixed to the blade. At the rear centrally, it has a double resistant support, of a substantially semioval shape fixed on the blade, the arrangement of a central and longitudinal blade being provided and, of a plurality of risky tiers, converging on the central support, which presents points perforated to allow the selective orientation of the own blade, existing two support arms that allow their installation to the own tractor. Being able to carry the shovel its own hydraulic system. (Machine-translation by Google Translate, not legally binding)
