Road grading pick with washer
A road grading pick includesa cutting head, a shank, a shoulder at a transition between the cutting head and the shank, and a polygonal-shaped washeror an oval- shaped washer. The shank is positioned in anopening of the washer to position the washer along a longitudinal length of the shank between a rearward end of the shank and the rearwardfacing surface of the shoulder. In a preinstalled position, the washer compresses a friction retainer on the shank of the road grading pick to facilitate seating of the road grading pick in a blade of a road grading apparatus. In an installed position on anadapter board for amoldboard of road grading equipment, thefriction retainer is no longer in the opening of the washer and thewasher prevents washer rotation and shields an underlying mounting surface while allowing rotation of the road grading pick.
