Abstract: In one embodiment, an electronic system comprises a display device to display data and processing logic coupled to the display device. The processing logic is configured to determine a duty cycle of at least one sensor for sensing flow of a product or particle through a product or particle line of an agricultural implement and to determine an amount of product or particles flowing through a line of the agricultural implement based on the duty cycle of the at least one sensor.

Abstract: An agricultural trench depth sensing system and method includes a light source (2002), a receiver (2003) and a sensor (2004). The light source directs light downwardly toward a trench previously opened in a soil surface. The receiver is disposed at an angle relative to the light source to receive reflected light. A sensor connected to the receiver senses a pattern of the reflected light. A monitoring system in communication with the sensor, generates a data frame containing triangulated line coordinates and intensity values of the reflected light indicative of a measured depth of the trench. The generated data frame may be associated with GPS coordinates for generating spatial maps and may be used to control operating parameters. The generated data frames may also identify relative soil moisture versus trench depth, or presence of dry topsoil or residue in the trench, or to identify seeds, seed spacing and seed depth.

Abstract: Systems, methods and apparatus for imaging and characterizing a soil surface and a trench in the soil surface formed by an agricultural implement. The sensors are disposed on the agricultural implement in data communication with a processor to generate the soil surface and trench images which may be displayed to the operator. In one embodiment, the sensors include one or more time of flight cameras for determining a depth of the trench and other characteristics of the surrounding soil surface and the trench, including detection of seeds, soil or other debris in the trench and moisture lines within the trench. The system may control operating parameters of the implement based on the generated images.

Abstract: A method of calibrating a yield sensor of a harvesting machine. The yield sensor generates a grain force signal as clean grain piles are thrown by the elevator flights against the sensor surface of the yield sensor. A grain height sensor is disposed to detect a height of the clean grain pile on each passing elevator flight. Each grain height signal is associated with a corresponding grain force signal by applying a time shift to account for a time delay between the time the grain height signal is generated and the time at which the impact signal is generated. The grain force signal is corrected by multiplying the grain force signal by a correction factor. The correction factor is the sum of the grain height signals divided by the sum of the grain force signals over a predetermined period.

Abstract: A soil apparatus (e.g., seed firmer) having a locking system is described herein. In one embodiment, the soil apparatus includes a lower base portion for engaging in soil of an agricultural field, an upper base portion, and a neck portion having protrusions to insert into the lower base portion of a base and then lock when a region of the upper base portion is inserted into the lower base portion and this region of the upper base portion presses the protrusions to lock the neck portion to the upper base portion.

Abstract: A ground-engaging component disposed at least partially within a planting trench formed by a planter row unit in a soil surface. The ground engaging component is capable of pivoting laterally side-to-side about a pivot axis as the ground engaging component advances in a forward direction of travel. The ground engaging component may include at least one wing extending laterally outward to form a side trench in a sidewall of the planting trench as the planter row unit advances in the forward direction of travel. The at least one wing may include a fluid outlet in fluid communication with a fluid source to deposit fluid into the side trench.
