Method of adjusting a sensor unit mounted on a field machine and an adjusting device therefor
First Claim
1. A method for guiding a field machine in relation to a working edge of a field, comprising the steps of:
- producing a signal from a sensor unit mounted on the field machine, wherein the sensor unit is automatically adjusted to a reference setting, said signal providing information about the location of the working edge of the field;
conveying said signal to a steering control unit in said field machine;
processing the signal in said control unit to produce a control command; and
controlling the field machine along the working edge of the field in response to the command produced by the steering control unit.

Abstract
An adjusting device for a sensor unit mounted on a field machine, or a harvester or tractor, and an associated method for positioning the field machine and sensor unit for locating a working edge of a field. The sensor unit can be mounted on a cutter bar assembly of a field machine via a supporting arm. The sensor unit may be adjusted horizontally or vertically. The sensor produces a signal that is communicated to a steering control unit to guide the field machine along the working edge of the field. The position or alignment of the sensor unit relative to a working edge of the field may be indicated on a two-dimensional display.

- 7. An adjusting device for a sensor having a first member for receiving the sensor, the sensor being mountable thereon, the first member being pivotably connected to a second member, the second member and the first member being relatively pivotable around a common axis to provide adjustment in a first plane, the second member being movably connected to a third member to provide adjustment in a second plane, the second plane being perpendicular to the first plane, the third member being a supporting member, the first and second members having a selective fastener to selectively release and fix the relative pivoting movement of the first and second members to define a first reference setting when fixed, the second and third members having a selective connector to selectively release and fix a location of the second member relative to the third member to define a second reference setting when fixed, the first and second reference settings defining an alignment for a sensor mounted in the device.
