A combine comprising: - a feeder housing for receiving harvested crop; - a separating system for threshing the harvested crop to separate grain from residue; - a grain bin for storing the separated grain; - a bin level sensor for detecting grain in the grain bin; and - a controller that controls the combine, the controller configured to: - generate a usable operating range by discarding a selected range of values from an operating range of the bin level sensor, - receive, from the bin level sensor, a first value indicating a level of grain in the grain bin, the combine being characterized in that the controller is further configured to: - select a shift value based on at least one of the terrain that the combine is traversing, in particular the grade of the terrain, the speed of the combine, the type of combine being operated, the type of grain being harvested or an input from the operator of the combine, - generate a shifted operating range by shifting the usable operating range by the shift value, - generate a second value by shifting the first value by the shift value, and - present the second value to an operator of the combine. - a feeder housing for receiving harvested crop; - a separating system for threshing the harvested crop to separate grain from residue; - a grain bin for storing the separated grain; - a bin level sensor for detecting grain in the grain bin; and - a controller that controls the combine, the controller configured to: - generate a usable operating range by discarding a selected range of values from an operating range of the bin level sensor, - receive, from the bin level sensor, a first value indicating a level of grain in the grain bin, the combine being characterized in that the controller is further configured to: - select a shift value based on at least one of the terrain that the combine is traversing, in particular the grade of the terrain, the speed of the combine, the type of combine being operated, the type of grain being harvested or an input from the operator of the combine, - generate a shifted operating range by shifting the usable operating range by the shift value, - generate a second value by shifting the first value by the shift value, and - present the second value to an operator of the combine. - generate a usable operating range by discarding a selected range of values from an operating range of the bin level sensor, - receive, from the bin level sensor, a first value indicating a level of grain in the grain bin, the combine being characterized in that the controller is further configured to: - select a shift value based on at least one of the terrain that the combine is traversing, in particular the grade of the terrain, the speed of the combine, the type of combine being operated, the type of grain being harvested or an input from the operator of the combine, - generate a shifted operating range by shifting the usable operating range by the shift value, - generate a second value by shifting the first value by the shift value, and - present the second value to an operator of the combine. - select a shift value based on at least one of the terrain that the combine is traversing, in particular the grade of the terrain, the speed of the combine, the type of combine being operated, the type of grain being harvested or an input from the operator of the combine, - generate a shifted operating range by shifting the usable operating range by the shift value, - generate a second value by shifting the first value by the shift value, and - present the second value to an operator of the combine.
