Parts for JD 71 Planters

[bobhightower 1963]

I have a two row set of JD 71 planters, I need to replace the bearings on the seed opener disc
where can I get the parts and how do you get to the bearings

You can get these items from a John Deere dealer or a Yetter dealer. Yetter mfg owns the flex planter design and still sells it as a new unit. You are going to cut off the rivets, replace the bearing, and rivet back together (with the right bolt maybe could get away with that). I would price out complete discs before getting to carried away.
