Ty,

Probably not completely worn out but figured I was that far in changing them sort of made since. That way new blades and guards could wear together. Local CNH dealer has little combo wear tool that measures seed disk wear for JD/Kinzie, CIH and Great Plains. I could have got buy for another year but I had 2 openers that had lost the plastic dust cap on one side and the bearings were about shot in those.

I like to replace things while I am in there so just went ahead and did both.

I need to email you sometime after planting and get some follow up opinions on the B&R welding knife rolls.
