I had a peice of an old dried out tree limb about 1 inch in diameter and 5 inches long shoot out the front of the brush hog through the rubber flap, and nearly take off part of my left foot 2 years ago while brush hogging on my father in laws old Ford 600 . I heard the brush hog hit something, and then felt a hard swat on the side of my foot.It all happened so fast, I was in to much pain to step on the clutch to stop the tractor, luckily I had the presence of mind to shut the key off and let the tractor coast to a stop. When I looked down at my foot, my leather Red Wing work boot had a tear about 6 inches long where the soul meets the leather, and I could see my blood soaked sock through the boot. I stayed on the tractor and called for my wife, who had heard the crash of the brush hog and the tractor stop, and had already come out on the deck to look out back to check on me. When we removed my boot, my foot had a huge gash on the side of the arch, and my little toe was broken, and its nail had been comepletely torn off. I have made a complete recovery, but will never forget the lesson I learned that day. That old 600 jusd had floor boards hanging off the side of the trans , kinda in outer space, which left my feet totaly exposed to whatever came flying out of the front of the brush hog. From now on, I only brush hog with my Farm Trac, since it like most modern day tractors has an enclosed foot area {fenders and floor boards fit flush with each other}, and I don't brush hog when nobody is around any more.
