The locating device for an agricultural machine controlled by an automatic steering system includes a first locating device component (OV1) directed at a first portion of a field on which agricultural material is not present, but adjacent an edge (GK) of the agricultural material and producing a first locating signal (OS1), a second locating device component (OV2) directed at a second portion of the field containing the material and adjacent, but not including, the edge of it and producing a second locating signal (OS2), a third locating device component (OV3) directed at a third portion of the field including the edge of the material and producing a third locating signal (OS3), a device for transmitting the first, second and third locating signals (OS1, OS2, OS3) to a regulating device (ST) for generating at least one hydraulic steering signal (SHL,SHR) from a standardized locating signal (NOS) to control the steerable wheels (HR) according to a predetermined locating criterion and a device for generating the standardized locating signal (NOS) by determining a preset range parameter from the first and second locating signals (OS1,OS2), determining a null point value as an average value of the first and second locating signals (OS1,OS2) and deriving the standardized locating signal (NOS) from the third locating signal (OS3) and the null point value.
