Brush Hog: A heavily built rotary mower that attaches to the back of a farm tractor via a three point hitch. Good for wacking through dense plant growth. Who knew? I learned how to cut down everything in my path with the brush hog behind me. Ahead....I had a great view. Tractors measure hours, not miles. I put double digit hours on the tractor while brush hogging. Thank goodness for MP3 players and pod casts.
