Abstract
An apparatus and method for determining uniformity of a tilled surface of a seedbed prepared by a tillage tool of an agricultural tillage implement utilize a seedbed uniformity sensing arrangement including a sensing element having a sensor body adapted for vertically articulating attachment to the implement behind the tillage tool and defining a soil-contact surface configured to bear against the tilled surface. The sensing element includes a vertical position sensor including a strain gauge fixedly attached to the sensor body for generating a surface uniformity signal in response to bending loads imposed on the sensor body by vertical movement of the soil-contact surface as it rides along on the tilled surface. The surface uniformity signal is processed to provide an indication of the general uniformity of the tilled surface, and a surface control signal that is used for controlling operational parameters of the tillage implement.
