Automatic Start/Stop Controls For Agricultural Load and Transfer Equipment

Abstract

A scale controller system and method of using the system is disclosed. The scale controller is adapted for use with a grain cart or similar implement that includes a discharge opening and conveyor. The system includes a scale and a plurality of sensors that work together to automate numerous functions that are typically performed manually. For example, the present invention discloses a system that automatically records the amount of material loaded or unloaded by continuously monitoring the load on a scale and the RPMs of a power take-off shaft that drives a conveyor.
