Abstract
A vibratory mechanism is provided for a compacting work machine . The vibratory mechanism includes a first/outer eccentric weight and a second/inner eccentric weight . The second weight has a cavity with a movable mass that when rotated in a first direction opposes the first eccentric weight and when rotated in a second direction the movable mass combines with the first eccentric . The second eccentric weight is also manually indexable relative to the first eccentric to a plurality of distinct positions giving a plurality of different amplitude vibratory impact forces when rotated in either of the first and second directions
