I have been wanting a core aerator for quite sometime. I have been thinking about making my own but I found a Woods PL60 that I may be able to get at a decent price. Would my BX handle it fine? It has 96 spoons. If they are dull can I sharpen them to get some more life out of them? Everything Attachments has 10 spoons for $45. I would have $450 if I had to replace the spoons and if those are the correct size.
