Manure from pigs and cattle is usually spread on fields using a manure spreader. Specialized equipment, such as a soil stabilizer and a mechanical cement spreader is usually required. These include, e.g. the vibration/shaking devices, spreader clamp/spreader cloth version or scraping devices. Cleco-type fasteners are also available with a threaded mechanism to draw the spreader bar up. Metal can be used for bondage ties with handcuffs, metal hobbles and spreader bars. The first successful automated manure spreader was designed by Joseph Kemp in 1875. The Zetros is used as a fertiliser spreader in the South East of South Australia. Instead of a hook, they are equipped with a specialized handling tool called a spreader. Most modern combines are equipped with a straw spreader. Next after the starboard spreader is the port spreader. The ankles or wrists may be brought together or kept apart by a spreader bar. The broadened base of these spreader leaves is translucent, provided with a yellow line. Spreader wads and non-spherical shot are disallowed in some competitions. Propaganda organizations depended on it as the primary spreader of propaganda to women.
