Systems and methods for limiting reel adjustment in an agricultural header

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.

Automated implement level sensing control system of a work machine and method thereof

A method of controlling tilt of an agricultural implement being towed by a tow vehicle along a field includes providing a controller, a first sensor, a second sensor, and an actuator coupled to the implement. The method includes detecting a baseline level of the tow vehicle with the first sensor at a first location in the field, wherein the implement is located at a second location in the field spaced rearward of the first location. The controller determines when the implement will be at the first location in the field, and an implement level of the implement is measured with the second sensor once the implement is at the first location. The implement level is compared to the baseline level with the controller. The controller determines if the difference between the implement level and baseline level is within a tolerance range, and further controls the actuator as needed.

An agricultural machine (10) or, particularly, a mower for an agricultural machine includes a primary frame (13), a mowing unit (14) mounting a cutterbar therein, an adjustable element (17) and a tilt sensor (19). The adjustable element is adjustable in response to a signal from the sensor to re-configure a mowing angle between the cutterbar and/or mowing unit and a ground surface. Such reconfiguration results in adjusting an effective stubble height of the mower. The adjustable element may be positioned between the primary frame (13) and the agricultural machine (10) or between the primary frame (13) and the mowing unit (14). In the latter case the adjustable element (17) provides independent adjustment of a tilt angle of the mowing unit to a primary actuator (A).
