ABSTRACT:
A detachable moldboard dozer blade assembly for tractors having a push frame pivotally attached at a rear end thereof to the underchassis of a tractor. A frame structure is attached to the forward end of the push and provides for a vertical pivotal axis for the attachment of the dozer blade assembly. An attachment plate is pivotally connected transversely to the frame structure for blade movement in a horizontal plane and shim and plate means retain the attachment of the dozer blade assembly. An attachment plate is pivotally connected transversely to the frame structure for blade movement in a horizontal plane and shim and plate means retain the attachment plate to the dozer blade to permit vertical or tilt movement of the dozer blade relative to the attachment plate. Hydraulic piston means extend from the push frame to the attachment plate and from the attachment plate to the dozer blade to move the dozer blade about a vertical and horizontal plane.
