Abstract: A system and a method for tracking agricultural commodities, such as crop inventories, is based on measuring a flow of crop through an equipment unit during a period of time, and determining the flow of crop through the unit to be a transfer event. More particularly, there is measured a quantity of crop in a first equipment unit; followed by a detection of a presence of one or more additional equipment units proximate the first equipment unit; and by a determination of at least one crop transfer event between the first equipment and at least one of the additional equipment units based on a change in the quantity of crop in the first equipment unit and the detection of presence.

Abstract: An agricultural implement has a depth control system in which a position sensor directly measures linear translation of a hydraulic cylinder that lifts and lowers a work unit on an implement frame to set and adjust the depth of the work unit without the use of a rockshaft. The position sensor may be positioned adjacent to or integrally formed with the hydraulic cylinder, and provides a voltage to a controller remote from the implement. The controller automatically adjusts the flow of hydraulic fluid to and from the hydraulic cylinder to maintain the depth of each work unit at an operator-selected level and can be used to calibrate the actual position of multiple work units relative to the frame and to one another.
