I picked up a used 63" Millcreek Aerator this Fall at an auction. Used it this Fall to aerate the yard and set it aside until now. I wanted to remove all of the individual discs to inspect then and then reinstall with anti seize grease. There are three individual axles which hold a set of discs. The axles were seized into the holders which were bolted to the frames. I removed the three wheel sets and used heat, PB Plaster and a hammer to loosen the axles from the holders. They are came apart. Tines are all in good shape. The big decision now is if i give the unit a coat of paint. Great project for this weather.
