A pivot plate includes a central hub rotatably mounted on the shaft and an arm projecting outwardly from the central hub. An outer end of the arm forming a visible bucket position indicator. A linkage couples the bucket to the pivot plate so that the pivot plate rotates clockwise and counter-clockwise as the bucket rotates clockwise and counter-clockwise, respectively, with respect to the boom.
