A wrapping system for an agricultural baler, comprising: a material roll configured to hold a roll of wrapping material; a duckbill assembly configured to draw wrapping material from the material roll and comprising a duckbill motor; a bale size sensor configured to output bale size signals; and a controller operatively coupled to the duckbill motor and the bale size sensor, the controller being configured to: determine a starting size of a bale based on at least one received bale size signal from the bale size sensor; output an initiation signal to the duckbill motor to initiate a wrap cycle; determine, based on at least one received bale size signal from the bale size sensor, if a current size of the bale is less than the starting size of the bale by a defined amount after outputting the initiation signal; and output a successful wrap signal responsively to determining that the current size is less than the starting size by the defined amount; characterized by: the wrapping system further comprising a brake associated with the material roll and configured to apply a braking force to the material roll to stop rotation thereof; and the controller further being configured to output a warning signal to the brake to stop rotation of the material roll if the current size of the bale after the wrap cycle has ended is not less than the starting size by the defined amount. a material roll configured to hold a roll of wrapping material; a duckbill assembly configured to draw wrapping material from the material roll and comprising a duckbill motor; a bale size sensor configured to output bale size signals; and a controller operatively coupled to the duckbill motor and the bale size sensor, the controller being configured to: determine a starting size of a bale based on at least one received bale size signal from the bale size sensor; output an initiation signal to the duckbill motor to initiate a wrap cycle; determine, based on at least one received bale size signal from the bale size sensor, if a current size of the bale is less than the starting size of the bale by a defined amount after outputting the initiation signal; and output a successful wrap signal responsively to determining that the current size is less than the starting size by the defined amount; determine a starting size of a bale based on at least one received bale size signal from the bale size sensor; output an initiation signal to the duckbill motor to initiate a wrap cycle; determine, based on at least one received bale size signal from the bale size sensor, if a current size of the bale is less than the starting size of the bale by a defined amount after outputting the initiation signal; and output a successful wrap signal responsively to determining that the current size is less than the starting size by the defined amount; characterized by: the wrapping system further comprising a brake associated with the material roll and configured to apply a braking force to the material roll to stop rotation thereof; and the controller further being configured to output a warning signal to the brake to stop rotation of the material roll if the current size of the bale after the wrap cycle has ended is not less than the starting size by the defined amount. the wrapping system further comprising a brake associated with the material roll and configured to apply a braking force to the material roll to stop rotation thereof; and the controller further being configured to output a warning signal to the brake to stop rotation of the material roll if the current size of the bale after the wrap cycle has ended is not less than the starting size by the defined amount.
