I bought a old Kewaunee transport disk at a auction. It was in transport position, wheels down. I trailered it home about 75 miles over Michigan backroads. After I got it home, I started to grease it, the old thing had about a million zerks. It was still on the trailer, and I climbed into it to grease the zerks there. After 3 tubes of grease, I was standing inside the disk, when it suddenly went down. The only thing holding the thing in transport position was rust. A little grease fixed that!! As it dropped, one of the 20 in blades hit the toe of my boot, glanced off the steel toe insert, and cut into the oak deck about a inch. It cut right thru the edge of the sole, ripped off a chunk of leather. I could see my white sock!! I wiggled my toe, it wiggled back. No injury, but I went right out and bought a new pair of steel to Redwings the next day!! If I'd had my gym shoes on, I'd lost a toe or worse.
