System and method for controlling spreader output from a harvester

A harvester comprising:

• a chopper configured to receive an agricultural material removed from a field by the harvester, and to chop the agricultural material;
• and
• a spreader system comprising first and second rotatable spreaders;
• a control system configured to adjust a position of the spreader system in a perpendicular direction with respect to a rotational axis of the chopper, in a parallel direction with respect to the rotational axis of the chopper, or a combination thereof such that at least one of a lateral position and longitudinal distance between the chopper and the first and second rotatable spreaders is changed, and to evenly distribute the agricultural material onto the field using the first spreader and the second spreader.

A method for distributing agricultural material removed from a field by a harvester, comprising:

• detecting a first force applied to a first panel or vane using a first sensor;
• detecting a second force applied to a second panel or vane using a second sensor;
• comparing the first and second forces;
• and
• adjusting at least one of a lateral and a longitudinal position of a spreader system with respect to the harvester based at least partially on the first and second forces.
