Automatic mass-flow sensor calibration for a yield monitor

1. A method of calibrating a mass-flow sensor on a yield monitor of a combine, comprising the steps of:

harvesting grain using the combine;

transferring the harvested grain to a location where its actual weight can be determined;

providing a wireless communication device on the combine;

transmitting a signal having information relating to the actual weight of the harvested grain to the wireless communication device on the combine;

determining a threshold value associated with a time increment at the wireless communication device on the combine;

determining if the signal that is transmitted to the wireless communication device is sent within the threshold value; and

calibrating the mass-flow sensor using the information.

2. The method of claim 1 , wherein the harvested grain is transferred using a grain carrier.

3. The method of claim 1 , further comprising the steps of:

providing a grain carrier for transferring the harvested grain;

and weighing the grain on the grain carrier.

4. The method of claim 3 , further comprising the step of providing a remote wireless communication device on the grain carrier for transmitting the information to the combine.

5. The method of claim 1 , further comprising the steps of:

providing a truck for transferring the harvested grain; and

weighing the grain on the truck.

6. The method of claim 5 , further comprising the step of providing a remote wireless communication device on the truck for transmitting the information to the combine.

7. The method of claim 1 , wherein the information is transmitted to the wireless communication device on the combine automatically.
