A system for calibrating tool depth as an agricultural implement is moved across a field may include an implement frame and a ground-engaging tool supported on the implement frame, with the ground-engaging tool configured to penetrate soil present within the field to a penetration depth. Additionally, the system may also include a frame position sensor configured to capture data indicative of a distance between the implement frame and a surface of the field. Furthermore, a controller of the disclosed system may be configured to determine a penetration depth value of the ground-engaging tool based on a received input. Moreover, the controller may be configured to determine a correction factor based on the data captured by the frame position sensor. In addition, the controller may be configured to adjust the determined penetration depth value based on the determined correction factor to calibrate the penetration depth value.

A method of controlling the downpressure on an air seeder that has a plurality of seed assemblies and a plurality of fertilizer assemblies each applying an adjustable downforce, wherein the method includes keeping a total downforce applied by all of the plurality of seed assemblies and all of the plurality of fertilizer assemblies less than a maximum downforce. The method may also include keeping the downforce applied by each of the fertilizer assemblies less than the downforce applied by each of the seed assemblies.

Systems and methods are provided for determining a soil roughness measure. A transducer transmits an ultrasonic signal towards a soil surface and receives a first echo signal of the ultrasonic signal and a second echo signal of the ultrasonic signal. A first distance between the transducer and a first point on the soil surface is calculated based on the first echo signal of the ultrasonic signal. A second distance between the transducer and a second point on the soil surface is calculated based on the second echo signal of the ultrasonic signal. A soil roughness measure of the soil surface is determined based on a difference between the first distance and the second distance.

A system for detecting the levelness of ground engaging tools of a tillage implement including an agricultural implement including a frame and tool assemblies supported relative to the frame. The tool assemblies each include a toolbar coupled to the frame and one or more ground engaging tools coupled to the toolbar. The system further includes sensors coupled to two of the tool assemblies and configured to capture data indicative of a load acting on the one or more ground engaging tools of the tool assemblies. Additionally, the system includes a controller configured to monitor the data received from the sensors and compare at least one monitored value associated with the load acting on the ground engaging tool(s) of each of the tool assemblies. Moreover, the controller is further configured to identify the ground engaging tool(s) are not level when the monitored value(s) differ by a predetermined threshold value.

A litter distribution apparatus provides for even distribution of a bedding material to an animal containment area for animal husbandry operations. The distribution apparatus has vertically adjustable skid legs that support the apparatus at a desired elevation as it is drawn across a ground surface of the containment area. A frame and litter containment skirt allow for the accumulation of the bedding material and even disposition along the ground surface based on the selected elevation of the skid legs. The skid legs may be vertically adjustable via an actuator.

A method for adjusting a seed depth associated with depositing a seed within a furrow in a field during a planting operation of an agricultural implement determining, by a computing device, a target seed depth based on a moisture content of the soil within the field. The method also includes sensing, by the computing device, a seed depth parameter indicative of a seed depth of the seed relative to a ground surface of the field. The method further includes comparing, by the computing device, the seed depth parameter to a target seed depth parameter that describes the target seed depth. In addition, the method includes initiating, by the computing device, a control action configured to adjust the seed depth parameter towards the target seed depth parameter.
