The Brush Hog case that I mentioned elsewhere had a protective plate removed (it was apparently commonly removed by farmers) and attached to an older tractor.

The Brush Hog case that I mentioned elsewhere had a protective plate removed (it was apparently commonly removed by farmers) and attached to an older tractor. When the operator (not the owner who made the change) was mutilated from the mower, Brush Hog was liable because it wasn't harder to remove that safety plate.
