     Stay with me on this... During peak road construction time, a lot of mud ends up on paved roads. In our area, the road builders will use a big broom mounted on a road grader to remove that mud, which is usually dried as hard as concrete. The broom has stiff wire bristles with pea-sized, hard rubber knobs on the ends. This broom basically grinds the top half inch or so of hard mud off the pavement. 

     Would something like this work to remove the rubbered-down portion of a dirt racetrack surface? If so, would that eliminate the rubber-down issue, or would it come right back during the feature race?

Wouldn't matter,  It would be slick again in two laps.   Have to till it and water and pack it     Those brushes also come in different forms.  From a road sweeper type bristle to a wire type that will remove the top layer of asphalt.

Why do you think that? Isn't it the top layer of rubber-coated mud that's hard and slick? Once you peel that layer off, it seems like the next layer would be softer and rubber free. 

The dry mud kn top also dries the layer ubder it. If you remove one dry layer and expose a slightly wetter layer it is only a short period of time before the 2nd layer is dry and slick also. You need to add water.

The grooming equipment I have seen us essentially what you describe but with times like a rototiller.

Also, where does the dry top layer go? If it is not removed and comes in contact with wetter dirt the wetter dirt becomes dryer. You need water.

Even though I may not know you, I 
care what most of you think!
