Abstract: 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).
