ABSTRACT:
A loader bucket orientation indicating system is provided for a bucket pivotal at an end of a loader boom. The system includes a support member having a base fixed to a side of an arm of the boom and a shaft projecting from the base. 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. A rotary device has a base fixed with respect to the boom arm, and has a rotary member coupled to the base by a non-rigid coupling. The rotary member has a visible mark thereon. The position of the bucket position indicator relative to the mark provides an indication of bucket orientation.A weight attached to the rotary member maintains it in a substantially fixed orientation relative to a horizontal plane.
