The invention relates to an agricultural working apparatus for use in forage harvesting and to a corresponding method with tines rotating about an axis A with corresponding tine ends. A device for changing the distance between the tine ends and the ground is also provided, as well as a sensor device for measuring a stubble height. An evaluation unit, in particular a decision support system, is provided to which the sensor device supplies measurement signals for the stubble height and which can determine a position of the tine ends as a function of the measured stubble height. A control device controls the device for changing the distance of the tine ends in order to set the determined position of the tine ends.

An improved rake wheel assembly is provided, the rake wheel having a plurality of spring tooth tines which pass through individual mounting holes in an outer hoop, each mounting hole includes a support member which supports a portion of the length of the spring tooth tine to better dissipate forces applied to the body of the spring tooth tine and increase tine durability and longevity.
