The double vertical auger fertilizer spreader (manure spreader/manure spreader) is a new type of agricultural machinery product that uses a tractor as a power source to return various types of manure, organic fertilizer, distiller’s grains, frozen fertilizer, hard block fertilizer, and wet manure with a moisture content of no more than 80% to the field. The product has a strong crushing ability and is spread evenly. It can increase soil nutrients, improve soil structure, effectively improve soil fertility and water retention, reduce environmental pollution caused by manure, and is of great significance to the mechanization of returning livestock and poultry manure to the field in agriculture and animal husbandry.
