There's just not enough thickness to put a blade to it, that will likely just peel it off the the brine dirt base. I think the only way you could do anything with it that might work would be a really big power trowel but you'd have to hit it when it's still wet. The fact that it's so thin now means the grooming window is so small between too wet & too dry. If you take a good look at it now you can also see the marks of the drain water direction as it went down the gurgler to the plant, they run across the course. By the marks in the pit area it appeared SCTA used some type of harrow to try & knock it down.

Will likely, or maybe, at least try it off course.
I think several Terrazzo grinders set up in a triangle on a platform might work. Not the actual grinders but blades
set up as in lawn mowers but longer, with stones attached. Or maybe just the blades from the grinders would be best as their all ready set up to change stones. Set up on a wheeled platform that can be raised or lowered. grinder linked with belts and powered by a good salvage yard pre-computer motor. Several feet long to hit the high spots and just wide enough to transport with out a permit.
Grinding the high spots filling in the holes an compacting the salt after scraping with their tire compactor.
Terrazzo grinder is a machine with grinding stones used to polish a marble slurry. Used for many commercial floors.
Something different needs to be done. Look at all the turn outs, give ups, spins and crashes in the results.
