A work vehicle includes a frame; an implement; a linkage assembly mounting the implement to the frame; a linkage actuator coupled to the linkage assembly and the frame and configured to reposition the linkage assembly relative to the frame; a sensor configured to generate sensor position data associated with at least one of the linkage assembly and the linkage actuator representing a linkage position; an operator interface configured to receive operator input from an operator associated with the linkage actuator representing a velocity request; and an electronic control system having processing and memory architecture operatively coupled to the sensor, operator interface, and linkage actuator. The electronic control system is configured to generate an actuator command for the linkage actuator based on the velocity request and the linkage position that, upon execution, results in a constant velocity of the implement for the operator input regardless of the linkage position.

A work vehicle includes a link mechanism to be equipped with a work implement, a drive mechanism to drive the link mechanism to ascend and descend the work implement, and a control lever is to be operated to ascend and descend the work implement. The work vehicle includes a first displacement transmission mechanism, an additional operational mechanism, and a second displacement transmission mechanism. The first displacement transmission mechanism links the drive mechanism and the control lever to transmit a displacement of the control lever to the drive mechanism. The additional operational mechanism is configured to operate the control lever at a location apart from a position of the control lever. The second displacement transmission mechanism mechanically links the additional operational mechanism and the control lever without interposing the first displacement transmission mechanism to shift the control lever in accordance with an operation of the additional operational mechanism.

A work vehicle includes a lifting mechanism to control at least one of a height and a posture of a work machine connected to the work vehicle. The lifting mechanism is able to control at least one of the height and the posture by using a hydraulic drive. The work vehicle includes an oil-temperature acquirer to acquire an oil temperature to be used for the hydraulic drive, a maximum oil amount setter to set a maximum oil amount according to the oil temperature acquired by the oil-temperature acquirer, the maximum oil amount being a maximum value of a supply amount of oil used to drive the hydraulic drive, and a hydraulic drive controller to control the hydraulic drive below the maximum oil amount set by the maximum oil amount setter.

An agricultural system includes an arm that supports a cutter bar assembly and is coupled to a fluid-filled biasing member such that the fluid-filled biasing member imparts a torque onto the arm. The agricultural system further includes an actuator and a controller. The actuator is coupled to the fluid-filled biasing member and is configured to move the fluid-filled biasing member relative to the actuator to change the torque imparted by the fluid-filled biasing member onto the arm. The controller is configured to determine a target position of the arm associated with a leveled configuration of the cutter bar assembly, receive an input to set the cutter bar assembly in the leveled configuration, and output a signal to instruct the actuator to set the fluid-filled biasing member relative to the actuator based on the target position upon receiving the input to set the cutter bar assembly in the leveled configuration.

A system for limiting plugging within an agricultural implement. The system includes a ground engaging tool configured to be supported by the agricultural implement. An actuator is coupled to the ground engaging tool. The actuator is operable to apply a down pressure on the ground engaging tool. A soil moisture sensor is positioned forward of the ground engaging tool. The soil moisture sensor is configured to measure a soil moisture forward of the ground engaging tool. A controller is communicatively coupled to the soil moisture sensor. The controller is configured to receive, from the soil moisture sensor, a signal that corresponds to the soil moisture forward of the ground engaging tool. The controller is further configured to adjust the down pressure on the ground engaging tool applied by the actuator based at least in part on the signal from the soil moisture sensor.

An agricultural system includes a frame, a cutter bar assembly configured to move relative to the frame during an operation of the agricultural system, a reel assembly configured to guide crops to the cutter bar assembly during the operation of the agricultural system, and a controller. The controller is configured to receive feedback indicative of a profile of the cutter bar assembly, set a position boundary of the reel assembly based on the feedback, and block movement of the reel assembly to a position beyond the position boundary of the reel assembly.

A support system for an agricultural header includes a first actuator configured to couple to a frame of the agricultural header and to a first element of the agricultural header. The support system also includes a second actuator configured to couple to the frame of the agricultural header and to a second element of the agricultural header. Furthermore, the support system includes a third actuator configured to couple to the frame of the agricultural header and to the second element of the agricultural header. The support system also includes a fluid supply system configured to provide pressurized fluid to the first actuator and to the second actuator. The third actuator is fluidly isolated from the fluid supply system, the first actuator, and the second actuator.
