About any agricultural dealer will have the shank tips available that are a friction fit and just need to be driven on with a 5 pound hammer. I had forgotten that one of mine came off when it was new. The replacement tip was $13. My dealer told me that the tips themselves are meant to be "sacrificial" and pull off if a large object is hit to preserve the more expensive scarifier shank. BTW, I only drop the scarifiers when I'm trying to pull up the base to help repair pot holes. 90% of the time my scarifiers are up and not getting any wear.
I was just leafing through the owners manual and they have the tips listed, a "normal" tip and an optional "wide flare" tip with part#'s. I use the shanks often. the gravel gets hard enough packed that the blades just skim across the top and takes way too many passes to pick up enough gravel to spread properly. I also find there are more fines an inch below the surface than near the top which the scarifiers bring to the surface that can then get re-mixed and provides a much better closer to class-a spec mix than just the top 1/4-1/2 inch layer does. Unless the gravel is soft I always use the shanks first then raise them for the grading. Another benefit of using the scarifiers is that they provide a multitude of channels parallel to the road which any standing water will congregate lengthwise which seems to help prevent potholes in areas with less than optimal slope.
Not only do break-away tips prevent shank damage but they also prevent damage to the shank support tubes.
