An analysis of rotary lawn mower accident statistics showed that measures must be undertaken to reduce or to guard against the hazards of operating these machines. A cantilever rod blade guard was designed, built, developed, and tested. The rotary mower, when equipped with a blade guard, mowed the lawn satisfactorily and yet, when encountering a test object (a dressed chicken), passed over it without inflicting injury to the test object.
