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.
In a nutrient material spreader comprising a main frame supported on ground engaging wheels, a tank mounted on said frame for receiving material to be distributed, a conveyor, a conveyor drive motor for driving the conveyor so that the conveyor conveys material received in said tank to a discharge area, an opening in said tank in the vicinity of said discharge area, and at least one slinger driven by a slinger motor and mounted outside said tank for receiving material discharged through said opening and dispersing the material on a field as the tank is transported over the field, the improvement comprising:
In a nutrient material spreader comprising a main frame supported on ground engaging wheels, a tank mounted on said frame for receiving material to be distributed, a conveyor assembly including an auger rotatably mounted in said tank for conveying material received in said tank to a discharge area, an opening in said tank in the vicinity of said discharge area, distribution means mounted outside said tank, including means in the vicinity of said opening for receiving material discharged through said opening and distributing it as the tank is transported over a field, the improvement comprising:
In a nutrient spreader having a conveyor driven by a motor for conveying nutrient material to a slinger which disperses the nutrient material onto a field, a control system for controlling dispersal of nutrient material onto the field so that an optimum amount of nutrient is spread over each cell of the field, said control system comprising:
In a manure spreader having a main frame supported for transport on ground engaging wheels, a tank mounted on said frame for receiving manure to be distributed, a conveyor assembly mounted in said tank and driven by a motor for conveying manure received in said tank to a discharge area, an opening in said tank in the vicinity of said discharge area, distribution means mounted outside said tank in the vicinity of said opening for receiving manure discharged through said opening and distributing it as the tank is transported over a field at variable speed, the improvement comprising:
