I picked up a potato seed cutter for $75 at the tractor show over the weekend, had no clue what it was until i got home and found a photo of one...turned out to be a John Deere Hoover Cutter. Just how rare are these? I noticed people had put "rare" in the ad of several that sold. Any info would be appreciated, I'm not sure what year model this one is, the only thing missing is the fingers that come up from the bottom that i'm thinking held the potato in place? This is a barn find, surface rust on it, hardly any paint left, would you guys paint and decal it or leave it as is. I will be replacing the knives and using it come spring. Photo below
