Abstract
A material spreader comprising a mobile tank for receiving and discharging waste material, such as manure. The spreader includes a conveying assembly comprising one or more augers rotatably mounted in the tank for conveying material received in the tank to a discharge area. An opening in the vicinity of the discharge area permits material to be dispensed to a slinger assembly mounted outside the tank adjacent the opening. Material is distributed by the slinger in a controlled pattern as the tank is transported over a field. A control system is provided for selectively controlling the rate and pattern of the material being distributed, based on characteristics of the material. A field is divided into cells and data relating to the nutrient demand of each cell is collected and stored in tables in a memory. A GPS receiver detects the location of the spreader as it moves over a field. Nutrient demand data, specific to the cell in which the spreader is located, is the read from the memory to control the rate at which nutrient material is dispersed from the spreader.
