These shafts, and their connecting points, are prime areas for serious entanglement. These shafts can easily amputate a limb or entangle the body with gruesome results, and must be shielded. Operators should always shut off spreaders before scraping the sides, and should never enter a running spreader. Contact with shafts, beaters or augers can be fatal. Scarves, strings on hooded sweatshirts, ragged clothing or other clothing items which can become entangled should never be worn around any machinery.
Road transport can also be hazardous.
A bright clean SMV emblem, mounted on the tractor or spreader, must be visible to motorists.
