I have a old Deere planter and the disc openers are rusted and won't spin
I have sprayed them with Pb blaster, and heated it, no luck.
Any help would be appreciated.
Mack hopefully you see this, you always seem to have answers for my questions. I can't thank you enough

If they have bushings, press them apart, clean them up, oil and put back togather. If they have bearings, best to replace bearings. A rusted bearing cleaned up and oiled has a short life. MACK

Depending how rusted the bearing is I have had luck with some IH disc harrow bearings. Drill a very small whole in the seal and add grease,fill whole silicone gasket maker. Pulled with a crawler so never over 4.5 MPR. Planter bears should be much smaller and cheaper so new may be a much better deal to just put new on.
