Make certain the driver knows where the helper is at all times when hitching a tractor to an implement. Do not move between the two objects to complete the hitching until the backing vehicle is completely stopped and the brake is set. Never stand between the tires of an articulating four-wheel drive tractor. Use adequate blocking or lock-out devices when working under equipment. Feed rolls, grinders, and forage harvesters.
Machines are faster and stronger than people.
Never attempt to hand-feed materials into moving feed rollers. Always stop the equipment before attempting to remove an item that has plugged a roller or that has become wrapped around a rotating shaft. Freewheeling parts, rotating or moving parts that continue to move after the power is shut off are particularly dangerous because time delays are necessary before service can begin. Allow sufficient time for freewheeling parts to stop moving. Rocks, stones, sticks, and pieces of chopped or cut crops.
