We have cowcare rope scrapers that scrape onto slats in front of the robots. I'm wanting to put slat mats down to help with white line as cows always seem to bull on the slats. Has anyone successfully got a scraper going from concrete passage up onto slat mats without it jamming or damaging the mats? A metal strip had been mentioned as a ramp, but thought that might come loose in time and cause more problems. Wondered about grinding the concrete down so the last mat finishes flush with the concrete, sounds easier said than done.
