Motor Grader V-Pick

I am looking for pictures of front mounted v-picks.I have seen some of the counties in Iowa run them.We have on old front mounted scarifier we would like to make one out of.we also have an old set of sandvicks to mount on it.I would also like to know the ones that run these if you prefer the v-pick type or just a dozer blade type. We already have dozer blades cut down for the graders with just strait blades on them.
