The system of claim 1 , further comprising a secondary fill-level sensor configured to provide an indication of when the harvested crops are at an initial fill-level within the storage volume, the computing system being configured to activate one of the first fill-level sensor or the second fill-level sensor based on the data received from the secondary fill-level sensor.

6. The system of claim 5 , wherein the secondary fill-level sensor is positioned within the storage volume of the crop transport receptacle at a predetermined offset distance relative to a bottom wall of the crop transport receptacle.

7. The system of claim 5 , wherein the secondary fill-level sensor comprises a switch-based fill-level sensor.

8. The system of claim 1 , at least one of the first fill-level sensor or the second fill-level sensor comprises one of a radar sensor, an ultrasound sensor, a sonar sensor, or a LIDAR sensor.

9. A system for monitoring crop fill-levels of transport receptacles, the system comprising:

a crop transport receptacle defining a storage volume configured to receive harvested crops;

a secondary fill-level sensor supported relative to the storage volume such that the secondary fill-level sensor is configured to detect when the harvested crops have reached an initial fill-level within the storage volume; and

a computing system communicatively coupled to both the primary fill-level sensor and the secondary fill-level sensor, the computing system being configured to determine whether the harvested crops have reached the initial fill-level based on data received from the secondary fill-level sensor, the computing system being further configured to, upon determining that the harvested crops have reached the initial fill-level, activate the primary fill-level sensor to allow a fill-level value associated with a fill level of the storage volume to be determined based on data received from the primary fill-level sensor.

10. The system of claim 9 , wherein the primary fill-level sensor comprises a reflection-based fill-level sensor.

11. The system of claim 10 , wherein the reflection-based fill-level sensor comprises one of a radar sensor, an ultrasound sensor, a sonar sensor, or a LIDAR sensor.
