Let's see now. Objects I've run over include but is not limited to: 1 plastic sewer cap (the mower won), 2 cast iron sewer caps (the mower won one and the cap won the other), bricks a whole bunch of times (they are real good for getting any stuck grass out from under the deck), tons of those darn plastic strips they tie newspapers with, a dog run wire, assorted wrenches of various sizes, a large copper plumbing fixture and a 1" diameter 4' long piece of rope which stopped the mower cold.
