Abstract
A harvesting machine with an automatic steering mechanism consists of a self-propelled machine with a cutterbar mounted in the driving direction. The harvesting machine also has generally-known locating devices to scan the crop edge, in particular, the border between the mowed and unmowed crops. The location devices produce signals that are processed by a controller and, via devices well-known in the art, are utilized by the automatic steering mechanism. The crop edge is scanned in at least two variable distances in front of the cutterbar. The controller processes at least two locating signals received in variable scanning distances in front of the cutterbar. The locating signals are used by devices well-known in the art for the automatic steering mechanism.
