Heh. I should have known better. We just got back from a week on Block Island (separate post to follow) and I had a lot of catching up to do. Like changing the smelly cat litter, doing laundry, shopping to restock the empty refrigerator, and mowing the lawn. With all the activities today, I didn't start mowing until dusk. Everything went fine until I began mowing in the back of the house and I apparently ran over something BAD. I say apparently because I could barely see, even with my tractor headlights. The mower made a horrible sound, hung up, and began digging into the earth. I inspected the blades and found that one was now angled about 60 degrees downward. Oh well, the crappy Sears tractor never cut very evenly anyway. Maybe instead of replacing the blades I'll just buy a real tractor--a John Deere.
