Patent attributes
An apparatus for earth working or material moving includes a first and a second blade oriented substantially parallel to one another. The two blades each have non-working blade faces positioned adjacent one another and working blade faces opposite one another. The two blades are moveable with respect to one another in the vertical direction, but fixed to one another in the horizontal direction. In this way, the working face of a first blade may be used in a first direction, and the working face of a second blade may be used in a second direction. The dual blade unit may be pivotally connected to an extending arm so that the angle of the first and second blades with respect to the direction of travel may be adjusted to the specifications of the user.
