Yesterday I took down a yard that had not been mowed in 2 years, as you can imagine it was more or less a wild field of 4 to 7 feet high. I walked through the yard and picked up 4 rugs, some boards, and a dog house.
While mowing a relatively short area, 18 to 24 inch high area I was going over and over a spot and kept noticing something hard my wheels where bumping over. After making 5 or 6 passes and finally getting to see the ground I noticed what I had been running over...
A full blown 4' long pitch fork. It had 4 prongs with 3/4" steel teeth... Gulp. Luckily it had been pushed down into the ground and didn't stick up anywhere. I picked it up and laid it on the front porch. I had my deck up high on 4", so it wasn't getting into anything too bad the entire yard. I saw 2 or 3 racquetballs, a frog, and a couple Frisbees. I did manage to vaporize a 6" PVC elbow that magically appeared, it was crunchy sounding.
