Yeah, thats the majority of what I've seen, a tractor with a rake.
I've also seen a tractor pulling a self contained scalping screen on one beach. It had its own motor, hydraulics etc. The sand went in the bottom, kinda like a pan, and was fed out the back. Every once in a while it would go empty its load of debris that was shaped and baled like a round hay bale. Kinda neat but the thing was huge.
I was trying to find a picture but don't know the exact name of it. :beatsme
