I was talking to Mark at church about the scrapers on these 7300 planters, and he mentioned that he had replaced his with the carbon tipped flat scrapers. It sounded like a good idea to me, so I went ahead and did the same. I have always had problems with these plastic spinning scrapers falling apart, and every spring I replace most of them. I did a little snooping and found out that JD doesn't even have this style scraper as an option on their new planters.
I think these should work a lot better.
