Abstract
A control system for a harvester having a residue discharge system operable to eject crop residue according to an adjustable residue discharge parameter, the control system including a processor, a memory, a human-machine interface, and a sensor configured to detect at least one of wind speed, wind direction, or humidity. The control system is configured to receive the signal from the sensor, receive an operator input corresponding to a desired residue management strategy selected from at least a first residue management strategy and a second residue management strategy, and adjust the residue discharge parameter based on the desired residue management strategy and the detected at least one of wind speed, wind direction, or humidity.
Claims11
A harvester, comprising:
- an inlet configured to receive crop;
- a blade configured to cut the crop into billet and extraneous plant matter;
- a cleaning system configured to generally distinguish between billet and extraneous plant matter such that billet is directed to a conveyor configured for discharging billet to a vehicle and extraneous plant matter is ejected through a hood as residue, wherein the hood is movable to control a direction of residue ejection;
- a sensor configured to detect at least one of wind speed, wind direction, or humidity;
- and
- a control system including a processor, a memory, and a human-machine interface, wherein the control system is configured to receive a signal from the sensor, configured to receive an operator input corresponding to a desired residue management strategy selectable from a plurality of mode options including at least 1) a first residue management strategy in which the control system is programmed to keep residue away from a first area including the harvester to control cleanliness of the harvester and 2) a second residue management strategy in which the control system is programmed to direct residue to a second area including ground around the harvester, wherein the control system is programmed to
- generate a current residue profile of ejected crop residue,
- compare the current residue profile with the desired residue management strategy, and
- move the hood based on the comparison and the detected at least one of wind speed, wind direction, or humidity.
A harvester, comprising:
- an inlet configured to receive crop;
- a blade configured to cut the crop into billet and extraneous plant matter;
- a cleaning system configured to generally distinguish between billet and extraneous plant matter such that extraneous plant matter is ejected from the harvester as residue and billet is directed to a conveyor configured to discharge billet to a vehicle, wherein a residue discharge rate is adjustable;
- a sensor configured to detect at least one of wind speed, wind direction, or humidity;
- and
- a control system including a processor, a memory, and a human-machine interface, wherein the control system is configured to receive a signal from the sensor, and configured to receive an operator input corresponding to a residue management strategy, wherein the residue management strategy is selectable from a plurality of mode options including 1) a first residue management strategy in which the control system is programmed to keep residue away from at least a portion of the harvester to control cleanliness of the harvester and 2) a second residue management strategy in which the control system is programmed to direct residue towards an area of ground to control residue spread, wherein the control system is programmed to
- generate a current residue profile of ejected crop residue,
- compare the current residue profile with the desired residue management strategy,
- and
- adjust the residue discharge rate based on the comparison and the detected at least one of wind speed, wind direction, or humidity.
