Weighing systems and methods for dynamic loads are provided. A plurality of sensors are configured to provide force information based on a weight of a bin and a weight of a material in the bin. An IMU is coupled to the bin and configured to provide gyroscope information and accelerometer information based on orientation and movement of the bin respectively. A controller is communicatively coupled to the plurality of sensors and to the IMU. The controller is configured to receive the force information from the plurality of sensors and the gyroscope information and the accelerometer information from the IMU. The controller is configured to compensate the force information based on slope of the bin to provide slope-compensated force information, filter the slope-compensated force information using a Kalman filter to provide filtered force information, and estimate the weight of the material in the bin based on the filtered force information.

A harvester including a frame supported by a drive assembly for movement along a support surface, a head unit coupled to the harvester and configured to selectively harvest crop material, a camera coupled to the frame and configured to generate one or more images of a field of view, and a controller in operable communication with the camera and the head unit, where the controller is configured to determine one or more crop attributes based at least in part on the one or more images produced by the camera.

ADJUSTABLE STUFFER CHUTE
20200375115 · 2020-12-03 ·

A baler (10) has a stuffer chute assembly (22) with upper and lower curved walls (44, 46) forming a stuffer chamber (24). A rear portion (54) of the upper wall (44) extends downwardly and forwardly from a baling chamber (12) and a forward portion (50) extends above an inlet opening to the stuffer chamber (24). The upper wall (44) has a plurality of laterally spaced-apart wrappers (52, 56), with adjacent wrappers forming slots (70, 72) extending generally from said crop receiving inlet opening to an outlet opening (48) for cooperation with tines (40) of a feeding mechanism (36). The wrappers (52, 56) are movable relative to the lower wall (46) at a forward end (60) and at a rearward end (66) of the upper wall (44) so as to change a cross-sectional dimension of the stuffer chamber (24). The baler (10) has a forward wall adjusting mechanism (80) for setting a forward end (60) of the upper wall (44) in a predetermined position, and a rear wall adjusting mechanism (110) for setting a rear end (66) of the upper wall (44).
