ABSTRACT:
A screed assembly for attachment to the boom arm of a mechanical hoe, including a first elongated member, an elongated ground-engaging structural member extending therefrom, a hoe connection interface and a hydraulic boom connection interface on the first elongated member, and a blade-engaging assembly operationally connected to the first elongated member. An elongated blade portion is pivotably connected to the blade-engaging assembly, a first pivot actuator is operationally connected between the first generally elongated portion and to the blade-engaging assembly, and a second pivot actuator operationally connected to the blade-engaging assembly and the elongated blade portion. Energization of the first pivot actuator pivots the blade engaging assembly relative to the first elongated member and energization of the second pivot actuator pivots the blade relative to the blade-engaging assembly.
