It seems like once every two-three weeks there is a snapped pull cord on something. Going to the hardware store for a replacement cord is a pain. And, yes, we try to be gentle when starting equipment, or at least I do, but there is always a broken cord somewhere. What is a very durable rope material that can be exposed to the elements well that you guys would replace the stock pull cord with? Sometimes the trimmers, blowers, and walk behind do get exposed to the elements, and that could be a problem with the standard pull cords.
