ABSTRACT:
The present invention is directed toward a loader bucket which has a back bucket assembly, a front bucket assembly that pivotably mounts to the back bucket assembly forming an extension thereof in the closed position and an actuator for pivoting the front bucket assembly relative to the back bucket assembly. The front bucket assembly includes an ejector panel that is adapted to swing behind the front bucket assembly and through the back bucket assembly as the front bucket assembly is pivoted by the actuator relative to the back bucket assembly. As the ejector panel sweeps through the back bucket assembly it sweeps out of the back bucket assembly without dumping the back bucket assembly. The lower wall of the back bucket assembly is cylindrically contoured to closely clear the ejector panel as it sweeps through the back bucket assembly.
