Abstract: A mobile material handling machine includes a material handling element and an operator's control cab. A plate is pivotally attached to the material handling element in line with the operator's line of sight from the cab towards the element. The plate has first indicia on the edges thereof; second indicia on the top surface thereof; and third indicia on the bottom surface thereof. The first indicia is in line with the operator's line of sight when the material handling element is positioned at a predetermined angle relative to the operator's cab.

Abstract: A means for pivotally mounting the bellcrank of a bucket linkage between the boom arms of a loader, including pivot castings secured to each of the boom arms, a shaft extending through said pivot castings and the bellcrank, a plate secured to one end of the shaft and bolted to the adjacent pivot casting to prevent rotation of the shaft relative to the boom arms, and a second plate bolted to the other end of said shaft to limit inward axial movement of the shaft relative to the adjacent pivot casting.
