HARRISON, Ark. - After a farmer's arm was ripped off in a tractor accident, he picked up the limb, climbed back on the tractor and went home to get help. "What was I supposed to do? Lie there and die?" James Arlen Mondy's wife quoted him as saying. Doctors tried but were unable to reattach his arm after the Dec. 16 accident. Mondy was knocked off his tractor when it hit a hole and the spinning blades of a brush cutter chopped off his arm at the shoulder. As he made his way home, he stopped to open a gate, drove through, and then dismounted the tractor again to close the gate. He continued on his way and began to feel lightheaded. Luckily, a passing couple saw him and were able to summon help.
