Abstract: A method for constructing a seawall section includes coupling an end of a substantially-waterproof barrier member to a footing. A concrete form is mounted to the footing such that a top end of the form is higher than an exposed upper surface of the footing. The concrete form defines at least part of a fill volume. Another end of the barrier member is coupled to the concrete form such that the barrier member extends over a side of the concrete form opposite the fill volume. Concrete is then poured into the fill volume and cured to form the seawall section. Prior to the curing, a body of water at the footing may be higher than the upper surface of the footing. However, the barrier member prevents water from entering the fill volume through the concrete form.

Abstract: A method to prevent drift in an agricultural implement. Drift is when one side of an agricultural implement is further behind or further ahead of the other side of the agricultural implement in a direction of travel. Drift can be controlled by increasing a downforce on the side that is further ahead, decreasing force on the side that is further behind, or a combination of both. The force can be a moment of force.

Abstract: An agricultural implement has implement settings for soil engaging tools that are controlled based on measured temporal and long-term soil properties in a field. A controller receives data from various soil and optical sensors and provides decision support for adjusting the implement settings. The soil sensors include a square or modified square electrical array that includes two independent, isolated disk coulters running side-by-side followed by two independent, isolated soil engaging runners. One runner has an optical sensor for organic matter, and the other runner has a temperature and moisture sensor. Above-ground optical sensors can be used to measure soil and plant material ahead of and behind the soil engaging tool. The controller can provide real time alerts to an operator that adjustments to the implement settings are needed, or the adjustments can be made automatically based on operator set thresholds, factory settings, or historical individual or global grower adjustments.

Abstract: One or more techniques and/or systems are disclosed for proving operation of a vehicle towing an implement. A hitch assembly can be used to adjust or distribute a vertical downward force that an attached implement applies to the frame of a vehicle towing the implement. A sensor assembly can identify the torque that is being applied to the front and rear axles. The torque data can be used to generate adjustments to the vertical load actuator, which can to adjust an amount of load applied to the front and/or rear axles. In this way, vertical load may be efficiently distributed between the front and rear axles automatically.

Abstract: A tillage implement has a frame with a center section and first and second outer wing sections hingedly attached to respective outer ends of the center section. Controlling a pressure in a secondary side of a hydraulic circuit enables adjustment of the downward pressure precharge provided by hydraulic cylinders based on a desired stiffness of the implement. Flow from a hydraulic supply through a pressure-reducing valve puts the downward pressure precharge on gauge wheels. Once this desired downward pressure precharge has been achieved, flow from the hydraulic supply is shut off and a check valve holds the pressure such that the hydraulic cylinders hold the gauge wheels in the desired position.
