Yes those are the ones......don't buy them! lol

After about the first 1500 acres they started falling apart and the rest of the season was miserable keeping them together. When they work they do work awesome even at 12+ mph. Every load I had to go around with a wrench and readjust and tighten pretty much every single one. For this year I'm going to run half the units with a knife and yetters new single disk closer and half with these that I will modify so they float.

I suppose they might be ok if you don't drive fast.
