  • Patent number: 11988132
    Abstract: A fan control system for a variable pitch fan of a work vehicle includes a blade pitch module that adjust a pitch of a plurality of blades of the variable pitch fan to generate airflow in a first direction. A reversing module selectively commands a fan reversal that includes instructing the blade pitch module to temporarily adjust the pitch of the plurality of blades to generate airflow in a second direction. A first timer module, in response to the reversing module commanding the fan reversal, resets and increments a first timer and compares the first timer to a first threshold. A first reversal prevention module, in response to the first timer being less than the first threshold, prevents the reversing module from commanding a fan reversal by indicating that a first type of fan reversal is not permitted.

  • Patent number: 11980135
    Abstract: A method of harvesting crop material includes capturing an image of a plurality of regions 28 of a field 50. The respective image of the regions 28 is analyzed to determine data related to constituent species of the crop material located within each of the regions 28. The data is associated with a region identifier 48 assigned to the respective one of the regions 28, and saved in a memory 42 of a computing device 30. The crop material in the field 50 is then harvested and formed into a bale. The harvested crop material formed into the bale is gathered from a subset 46 of the regions 28. A region identifier 48 of each of the regions 28 included in the subset 46 of the regions 28 is associated with the bale identifier 38, such that the data related to constituent species of the crop material included in the bale is associated with the bale and may be obtained by querying the computing device 30.

  • Patent number: 11980130
    Abstract: Methods and systems for operating a detasseler machine to optimize detasseling efficiency. Front-facing image data is captured by a camera positioned with a field of view in front of the detasseler machine as the detasseler machine operates in a crop field. A new set of machine operating parameters for the detasseler machine is periodically determined based on the a set of crop parameters indicated by the front-facing image data and control signals are transmitted to one or more actuators to operate the detasseler machine according to the determined set of machine operating parameters. In some implementations, rear-facing image data used to quantify missed tassels left by the detasseler machine and the machine operating parameters are further adjusted to reduce the missed tassel metric. The mechanism for determining the set of machine operating parameters is then retrained based on the adjusted machine operating parameters.

  • Patent number: 11983009
    Abstract: One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.
