An agricultural implement operating on a field surface with growing crop plants comprises a plurality of divider mechanisms mounted in front of the implement wheels. Each divider mechanism comprises a divider member comprising a diversion member tapering laterally from a front end of the divider member, operative to push the crop plants away from a path of the wheel, and mounted to the implement by a parallel link assembly. An actuator is connected to the parallel link assembly and moves the divider member up and down. A control is operative to activate each actuator, and a sensor system senses a divider height of each divider member above the field surface. The sensor system is connected to the control such that the control is operative to specify a desired divider height for each divider member.

A row unit of an agricultural implement includes an opening system configured to engage soil to form a furrow, sensors configured to detect a soil tightness, soil conditions, operational conditions, or a combination thereof, and a closing system configured to close the furrow. The closing system includes a first closing disc configured to engage the soil and close the furrow and a second closing disc configured to engage the soil and close the furrow. The row unit also includes a controller configured to receive feedback from the sensors and to control a position, an orientation, or both, of the first closing disc, the second closing disc, or both, in response to feedback from the sensors.

A position monitoring system for an agricultural system includes a controller having a memory and a processor. The controller is configured to receive a remote sensor signal from a remote sensor indicative of a state of a reference element on one of a work vehicle or an agricultural implement coupled to the work vehicle, determine an orientation of the agricultural implement relative to the work vehicle based at least in part on the remote sensor signal, and output a control signal to control operation of the agricultural system based at least in part on the orientation of the agricultural implement relative to the work vehicle.

The invention relates to lifting and adjusting devices for agricultural equipment. The attachment system includes a mounting frame with fastening means for its attachment to the vehicle, and an implement bearing frame capable of vertical movement relative to the mounting frame under the action of lifting devices fixed on the sides of the mounting frame; and a framework located in front of the agricultural implement for installing at least one safety device. By all the design features of the invention, the attachment system enhances the operational efficiency of agricultural equipment by reducing the probability of its damage at obstacle collision, improving operator safety, and preserving the environment.

An agricultural implement includes a plurality of ground-engaging tools configured to modify a surface configuration of an agricultural field and a hydraulically-controlled subsystem configured to modify an operating angle of the plurality of ground-engaging tools. The agricultural implement also includes a sensor coupled to the hydraulically-controlled subsystem configured to generate sensor signals indicative of a current operating angle of the plurality of ground-engaging tools. The agricultural implement also includes an implement control system configured to receive the sensor signals from the sensor to determine the current operating angle of the plurality of ground-engaging tools, and, upon determining the current operating angle is to be changed to a new operating angle, generate control signals for the hydraulically-controlled subsystem to modify the operating angle of the plurality of ground-engaging tools from the current operating angle to the new operating angle.

An agricultural implement includes a frame and a ground engaging tool assembly having a shank rotatably coupled to the frame and a ground engaging tool coupled to the shank. In addition, the agricultural implement includes a monitoring system having a sensor mounted to one of the frame or the ground engaging tool assembly and directed toward a target. The target is the other of the frame or the ground engaging tool assembly, and the sensor is configured to emit an output signal toward the target and to receive a return signal indicative of a measured position of the ground engaging tool assembly relative to the frame. The monitoring system also includes a controller configured to determine that the ground engaging tool assembly is in a deflected position in response to determining that a difference between the measured position and a working position is greater than a threshold value.

One or more techniques and/or systems for application of a supplemental downward force to a ground working implement. A mechanical advantage from a lever arm can be utilized to apply supplemental downforce to a ground working implement. A biasing force can be applied to the lever arm by a spring assembly at various locations. Moving the spring assembly along the lever arm can vary the amount of downward force applied by the lever arm to ground working implement. In some implementations, moving the spring assembly to a different end of the lever arm applies an upward force to a coupled ground working implement.
