Abstract: A system for scoring and standard analysis of user responses to an assessment test, wherein the system includes a scoring engine having one or more rubric items used to score and assess a candidate’s response to one or more free-text questions. A candidate’s response can be input into the scoring engine and optionally in communication with a machine learning classifier can produce one or more outputs. The outputs can include a score, recommendation, and user feedback among other things. The system can further include one or more machine learning classifier engines.

Abstract: Systems and methods for monitoring seed placement by a planting machine with a plurality of row units. An average seed placement metric is calculated for each individual row unit based on a data stream of sensor data corresponding to a defined calculation window. Each calculated metric is compared to a defined performance threshold and an error alert signal is transmitted based on the comparison. The calculation window can be adjusted by a user and the average seed placement metrics and the error alert signal are updated based on the adjusted calculation window. A graphical user interface also displays the calculated metrics for each individual row unit in a row data table and updates the row data table in response to receiving the user selection of the new calculation window.

Abstract: A windrower with a frame at a front end of the windrower and a cab coupled to the frame. The cab has a plurality of controls disposed in the cab for controlling the windrower. The windrower also has a lift arm with a first end and a second end, the first end being pivotally coupled to the frame, wherein the lift arm includes a transverse bend defined at a location between the first and second ends. A first coupler is coupled to the second end of the lift arm and a second coupler coupled to the lift arm between the first and second ends. The first coupler is configured to couple the frame to a rotary-style head and the second coupler is configure to couple the frame to a draper-style head.
