The conveying device is configured to convey material into or from the storage bin. A weighing device measures the weight of the storage bin and outputs a signal representing the weight to a controller. The controller is configured to disable the conveying device when the weight reaches a preset limit. ## Claims ### Claim 1 A system for controlling the amount of material moved by a conveying device of a farm implement, the farm implement having a storage bin for storing material, a conveying device having an input at a first end and a discharge at a second end, said system comprising: a weighing device configured to measure the weight of said bin and to output a signal representing said weight; a controller electronically coupled with said weighing device and configured to receive said signal representing said weight and to transmit a disable signal when said weight reaches a preset weight; and a conveyor control valve electronically coupled to said controller and configured to receive said disable signal from said controller and to disable said conveying device upon receiving said disable signal. ### Claim 2 (depends on 1) The system of claim 1, further comprising an input device configured to allow an operator to enter at least one weight limit and said preset weight is set to said at least one weight limit. ### Claim 3 (depends on 1) The system of claim 1, further comprising a user control switch configured to allow an operator to manually activate and disable said conveying device. ### Claim 4 (depends on 1) The system of claim 1, wherein said weighing device includes a scale display indicator that displays the weight of said storage bin and outputs an alarm when the weight of the material in the storage bin reaches a preset limit. ### Claim 5 (depends on 1) The system of claim 1, wherein said conveying device is a motor driven belt conveyor. ### Claim 6 (depends on 1) The system of claim 1, wherein said storage bin includes a discharge. ### Claim 7 (depends on 6) The system of claim 6, wherein said conveying device input is positioned to receive material from said storage bin discharge. ### Claim 8 (depends on 1) The system of claim 1, wherein said conveying device discharge is positioned over said storage bin. ### Claim 9 (depends on 1) The system of claim 1, wherein said conveyor control valve comprises a throttle actuator. ### Claim 10 A method for controlling the amount of material output from a conveying device, comprising steps of: storing material in a storage bin; with a conveying device, conveying material into or from said storage bin; with an electronic scale, monitoring the weight of said storage bin; providing one or more preset weight limits; sending a signal, with the electronic scale, representing the weight of said storage bin to a controller; determining if said weight of said storage bin meets or exceeds said preset weight limit; and with the controller, electronically controlling said conveyor to disable said conveyor when it is determined that said weight meets said preset weight limit. ### Claim 11 (depends on 10) The method of claim 10, further comprising steps of: with an input device, entering at least one weight limit; and setting said at least one weight limit as the one or more preset weight limits. ### Claim 12 (depends on 10) The method of claim 10, further comprising a step of providing a means for an operator to manually activate and disable said conveying device. ### Claim 13 (depends on 10) The method of claim 10, further comprising steps of: displaying the weight of a storage bin; and outputting an alarm signal when the weight of the material in the storage bin reaches a preset limit. ### Claim 14 (depends on 10) The method of claim 10, further comprising steps of: sending the alarm signal to said controller; and with the controller, disabling said conveying device upon receiving the alarm signal. ### Claim 15 (depends on 14) The method of claim 14, further comprising a step of discharging material from said storage bin. ### Claim 16 (depends on 10) The method of claim 10 further comprising a step of receiving the material discharged from said storage bin discharge at an input of said conveying device. ### Claim 17 (depends on 16) The method of claim 16 further comprising a step of discharging material from said conveying device into said storage bin. ### Claim 18 (depends on 10) The method of claim 10 further comprising a step of controlling said conveying device with a conveyor control valve electronically coupled to said controller and configured to receive a signal from said controller and disable said conveying device upon receiving the signal.
