So how about this:
At end of season I do a pretty thick wax job to keep my base from drying out.
Then I leave it unscraped.
Scraping is a pain, any reason at the start of the new season not to just go ride it and let the machine groomed granular scrape off the excess instead of doing it myself?
First day out the snow is usually pretty crappy anyways.
If that worked, why would you ever scrape...
